abstract: PURPOSE We evaluated the value of resistance training on measures of physical performance in disabled older women with coronary heart disease ( CHD ) . METHODS The study intervention consisted of a 6-month program of resistance training in a r and omized controlled trial format . Training intensity was at 80 % of the single-repetition maximal lift . Control patients performed light yoga and breathing exercises . Study participants included 42 women with CHD , all > or= 65 yr of age and community dwelling . Subjects were screened by question naire to have low self-reported physical function . The primary study measurements related to the performance of 16 household activities of the Continuous Scale Physical Functional Performance test ( CSPFP ) . These ranged from dressing , to kitchen and cleaning activities , to carrying groceries and walking onto a bus with luggage , and a 6-min walk . Activities were measured in time to complete a task , weight carried during a task , or distance walked . Other measures included body composition , measures of aerobic fitness and strength , and question naire-based measures of physical function and depression score . RESULTS Study groups were similar at baseline by age , aerobic capacity , strength , body composition , and in performing the CSPFP . After conditioning , 13 of 16 measured activities were performed more rapidly , or with increased weight carried , compared with the control group ( all P < 0.05 ) . Maximal power for activities that involved weight-bearing over a distance , increased by 40 % ( P < 0.05 ) . CONCLUSIONS Disabled older women with CHD who participate in an intense resistance-training program improve physical capacity over a wide range of household physical activities . Benefits extend beyond strength-related activities , as endurance , balance , coordination , and flexibility all improved . Strength training should be considered an important component in the rehabilitation of older women with CHD & NA ; Physical therapists seeking to use evidence to guide their practice may have limited time to read research reports . One way to reduce the time required to identify and read about the research that is relevant to a particular clinical question is to read a systematic review that summarizes multiple studies . This paper explains the process that is used to conduct systematic review s , which includes the establishment of a protocol , comprehensive search ing , appraisal of the quality of the included studies , data extraction and meta analysis , and consideration of the clinical and research implication s of the findings . We also consider how the reader of a systematic review can determine whether the review is likely to provide an unbiased ( believable ) estimate of the treatment effect . A systematic review of r and omized trials of a  cardiopulmonary physical therapy intervention is used as an example . The issue of appraisal of quality is then discussed further , with a demonstration of how one vali date d tool for quality appraisal ‐‐the PEDro scale‐‐can be used to evaluate a r and omized trial in cardiopulmonary physical therapy BACKGROUND Falls prevention is an international priority , and residents of long-term aged care fall approximately 3 times more often than community dwellers . There is a relative scarcity of published trials in this setting . OBJECTIVES Our objective was to undertake a r and omized controlled trial to test the effect of published best practice exercise in long-term residential aged care . The trial was design ed to determine if combined high level balance and moderate intensity progressive resistance training ( the Sunbeam Program ) is effective in reducing the rate of falls in residents of aged care facilities . METHOD A cluster r and omized controlled trial of 16 residential aged care facilities and 221 participants was conducted . The broad inclusion criterion was permanent residents of aged care . Exclusions were diagnosed terminal illness , no medical clearance , permanent bed- or wheelchair-bound status , advanced Parkinson 's disease , or insufficient cognition to participate in group exercise . Assessment s were taken at baseline , after intervention , and at 12 months . R and omization was performed by computer-generated sequence to receive either the Sunbeam program or usual care . A cluster refers to an aged care facility . INTERVENTION The program consisted of individually prescribed progressive resistance training plus balance exercise performed in a group setting for 50 hours over a 25-week period , followed by a maintenance period for 6 months . OUTCOME MEASURES The primary outcome measure was the rate of falls ( number of falls and days followed up ) . Secondary outcomes included physical performance ( Short Physical Performance Battery ) , quality of life ( 36-item Short-Form Health Survey ) , functional mobility ( University of Alabama Life Space Assessment ) , fear of falling ( Falls Efficacy Scale International ) , and cognition ( Addenbrooke 's Cognitive Evaluation-revised ) . RESULTS The rate of falls was reduced by 55 % in the exercise  group ( incidence rate ratio = 0.45 , 95 % confidence interval 0.17 - 0.74 ) ; an improvement was also seen in physical performance ( P = .02 ) . There were no serious adverse events . CONCLUSION The Sunbeam Program significantly reduced the rate of falls and improved physical performance in residents of aged care . This finding is important as prior work in this setting has returned inconsistent outcomes , result ing in best practice guidelines being cautious about recommending exercise in this setting . This work provides an opportunity to improve clinical practice and health outcomes for long-term care residents Frailty has emerged as an important risk factor for disability . Age-related declines in physical and physiological function lead to increased risk of loss of independence and poor quality of life . Recent evidence has shown the effectiveness of physical exercise programmes in preventing or reversing frailty . The aim of this study was to evaluate changes in the functioning of frail elderly individuals after undergoing  resistance training  for 3 days a week for 8 weeks . The effectiveness of exercise training was investigated in 48 frail elderly individuals who were r and omly assigned to the following intervention groups : high-intensity ( HI ; n=16 ; age : 69–96 years ) or low-intensity ( LI ; n=16 ; age : 77–93 years ) strength training groups or a control group ( n=16 ; age : 76–93 years ) with no specific exercise programme . Participants were assessed for muscle strength , physical function , activities of daily living , depression and quality of life . The HI group had significantly better results ( P<0.05 ) on the Short Physical Performance Test than the LI group ; however , the LI group did show a significant improvement in those scores , whereas the scores of the control group worsened . Results for the other evaluations were similarly favourable in both exercise groups ( P>0.05 ) . The study showed that LI exercise was as effective as HI exercise for most parameters tested . Exercise training is useful for the prevention or treatment of frailty , as it improves functioning by contributing positively to muscle strength , gait , balance and quality of life The goal of this study was to determinate the effects of physical training in older adults with mobility limitations . Thirty frail women ( 84 ± 6 years ) were r and omly assigned to a training or control group for 12 weeks of upper body physical training ( UBT ) performed sitting on wheelchairs . Trained subjects showed a significant improvement in arms strength ( + 29 % ) , and shoulder flexibility ( + 10 cm ) but did not improve in arms circumference . The activities of daily living ( ADLs ) were improved ( + 77 % ) , cognitive function as defined by the Mini-Mental State Examination ( MMSE ) was maintained in the trained group ( + 3 % ) and declined in the control group ( −21 % ) . These results demonstrate that UBT in dependent older women with mobility limitations can increase strength and improve ADLs Eighty-six elderly people with limited mobility and dependence in at least one activity of daily living were recruited to a home exercise study . The subjects ( mean age 82 years ) were allocated at r and om to either a strength exercise group , a mobility exercise group or a health education group . Subjects were visited for 30 minutes every 3 - 4 weeks by a physiotherapist who gave both verbal and written instruction . Sixty-nine of the original 86 completed the 6-month study , with five drop-outs from the strength group , ten drop-outs from the mobility group , and two drop-outs from the health education group . By the end of the study , there were no significant differences between the groups with regard to changes in outcome variables . The results showed a trend towards improvement in both the exercise groups in both Sit to St and and Timed Get Up and Go tests , but this failed to attain statistical significance . Further work is required to identify the optimal exercise intervention for this subgroup of the elderly population CONTEXT Hip fractures are common in the elderly , and despite st and ard rehabilitation , many patients fail to regain their prefracture ambulatory or functional status . OBJECTIVE To determine whether extended outpatient rehabilitation that includes progressive resistance training improves physical function and reduces disability compared with low-intensity home exercise among physically frail elderly patients with hip fracture . DESIGN , SETTING , AND PATIENTS R and omized controlled trial conducted between August 1998 and May 2003 among 90 community-dwelling women and men aged 65 years or older who had had surgical repair of a proximal femur fracture no more than 16 weeks prior and had completed st and ard physical therapy .  INTERVENTION Participants were r and omly assigned to 6 months of either supervised physical therapy and exercise training ( n = 46 ) or home exercise ( control condition ; n = 44 ) . MAIN OUTCOME MEASURES Primary outcome measures were total scores on a modified Physical Performance Test ( PPT ) , the Functional Status Question naire physical function subscale ( FSQ ) , and activities of daily living scales . Secondary outcome measures were st and ardized measures of skeletal muscle strength , gait , balance , quality of life , and body composition . Participants were evaluated at baseline , 3 months , and 6 months . RESULTS Changes over time in the PPT and FSQ scores favored the physical therapy group ( P = .003 and P = .01 , respectively ) . Mean change ( SD ) in PPT score for physical therapy was + 6.5 ( 5.5 ) points ( 95 % confidence interval [ CI ] , 4.6 - 8.3 ) , and for the control condition was + 2.5 ( 3.7 ) points ( 95 % CI , 1.4 - 3.6 points ) . Mean change ( SD ) in FSQ score for physical therapy was + 5.2 ( 5.4 ) points ( 95 % CI , 3.5 - 6.9 ) and for the control condition was + 2.9 ( 3.8 ) points ( 95 % CI , 1.7 - 4.0 ) . Physical therapy also had significantly greater improvements than the control condition in measures of muscle strength , walking speed , balance , and perceived health but not bone mineral density or fat-free mass . CONCLUSION In community-dwelling frail elderly patients with hip fracture , 6 months of extended outpatient rehabilitation that includes progressive resistance training can improve physical function and quality of life and reduce disability compared with low-intensity home exercise This r and omized controlled trial examined the effects of multicomponent training on muscle power output , muscle mass , and muscle tissue attenuation ; the risk of falls ; and functional outcomes in frail nonagenarians . Twenty-four elderly ( 91.9 ± 4.1 years old ) were r and omized into intervention or control group . The intervention group performed a twice-weekly , 12-week multicomponent exercise program composed of muscle power training ( 8–10 repetitions , 40–60 % of the one-repetition maximum ) combined with balance and gait retraining .  Strength and power tests were performed on the upper and lower limbs . Gait velocity was assessed using the 5-m habitual gait and the time-up- and -go ( TUG ) tests with and without dual-task performance . Balance was assessed using the FICSIT-4 tests . The ability to rise from a chair test was assessed , and data on the incidence and risk of falls were assessed using question naires . Functional status was assessed before measurements with the Barthel Index . Midthigh lower extremity muscle mass and muscle fat infiltration were assessed using computed tomography . The intervention group showed significantly improved TUG with single and dual tasks , rise from a chair and balance performance ( P < 0.01 ) , and a reduced incidence of falls . In addition , the intervention group showed enhanced muscle power and strength ( P < 0.01 ) . Moreover , there were significant increases in the total and high-density muscle cross-sectional area in the intervention group . The control group significantly reduced strength and functional outcomes . Routine multicomponent exercise intervention should be prescribed to nonagenarians because overall physical outcomes are improved in this population Objectives To determine whether a lifestyle integrated approach to balance and strength training is effective in reducing the rate of falls  in older , high risk people living at home . Design Three arm , r and omised parallel trial ; assessment s at baseline and after six and 12 months . R and omisation done by computer generated r and om blocks , stratified by sex and fall history and concealed by an independent secure website . Setting Residents in metropolitan Sydney , Australia . Participants Participants aged 70 years or older who had two or more falls or one injurious fall in past 12 months , recruited from Veteran ’s Affairs data bases and general practice data bases . Exclusion criteria were moderate to severe cognitive problems , inability to ambulate independently , neurological conditions that severely influenced gait and mobility , resident in a nursing home or hostel , or any unstable or terminal illness that would affect ability to do exercises . Interventions Three home based interventions : Lifestyle integrated Functional Exercise ( LiFE ) approach ( n=107 ; taught principles of balance and strength training and integrated selected activities into everyday routines ) , structured programme ( n=105 ; exercises for balance and lower limb strength , done three times a week ) , sham control programme ( n=105 ; gentle exercise ) . LiFE and structured groups received five sessions with two booster visits and two phone calls ; controls received three home visits and six phone calls . Assessment s made at baseline and after six and 12 months . Main outcome measures Primary measure : rate of falls over 12 months , collected by self report . Secondary measures : static and dynamic balance ; ankle , knee and hip strength ; balance self efficacy ; daily living activities ; participation ; habitual physical activity ; quality of life ; energy expenditure ; body mass index ; and fat free mass . Results After 12 months ’ follow-up , we recorded 172 , 193 , and 224 falls in the LiFE , structured exercise , and control groups , respectively . The overall incidence of falls in the LiFE programme was 1.66 per person years , compared with 1.90 in the structured programme and 2.28 in the control group . We saw a significant reduction of 31 % in the rate of falls for the LiFE programme compared with controls ( incidence rate ratio 0.69 ( 95 % confidence interval 0.48 to 0.99 ) ) ; the corresponding difference between the structured group and controls was non-significant ( 0.81 ( 0.56 to 1.17 ) ) . Static balance on an eight level hierarchy scale , ankle strength , function , and participation were significantly better in the LiFE group than in controls . LiFE and structured groups had a significant and moderate improvement in dynamic balance , compared with controls . Conclusions The LiFE programme provides an alternative to traditional exercise to consider for fall prevention . Functional based exercise should be a focus for interventions to protect older , high risk people from falling and to improve and maintain functional capacity . Trial registration Australia and New Zeal and Clinical Trials Registry 12606000025538 BACKGROUND The purpose of this efficacy study was to measure the dose-response effect of a free weight-based resistance training program by comparing the effects of two training intensities ( low-moderate and high ) of the knee extensor ( KE ) muscles on muscle function , functional limitations , and self-reported disability . METHODS The authors conducted a single-blinded , r and omized , placebo-controlled trial . Twenty-two institutionalized elders ( mean age , 81.5 years ) were assigned to either high-intensity strength training ( HI ; n = 8) , low-moderate intensity strength training ( LI ; n = 6 ) , or weight-free placebo-control training ( PC ; n = 8) . The HI group trained at 80 % of their 1-repetition maximum and the LI group trained at 40 % . All groups performed 3 sets of 8 repetitions , 3 times per week for 10 weeks . Outcome measures included KE maximal strength , KE endurance , and functional performance as assessed by 6-minute walking , chair-rising , and stair-climbing tests , and by self-reported disability . RESULTS KE strength and endurance , stair-climbing power , and chair-rising time improved significantly in the HI and LI groups compared with the PC group . Six-minute walking distance improved significantly in the HI group but not in the LI group compared with the PC group . Changes observed in HI were significantly different from those observed in the LI group for KE strength and endurance and the 6-minute walking test , with a trend in the same direction for chair-rising and stair-climbing . Changes in strength were significantly related to changes in functional outcomes , explaining 37 % to 61 % of the variance . CONCLUSIONS These results show strong dose-response relationships between resistance training intensity and strength gains , and between strength gains and functional improvements after resistance training . Low-moderate intensity resistance training of the KE muscles may not be sufficiently robust from a physiologic perspective to achieve optimal improvement of functional performance . Supervised HI , free weight-based training for frail elders appears to be as safe as lower intensity training but is more effective physiologically and functionally BACKGROUND The study tested the effect of strength and endurance training on gait , balance , physical health status , fall risk , and  health services use in older adults . METHODS The study was a single-blinded , r and omized controlled trial with intention-to-treat analysis . Adults ( n = 105 ) age 68 - 85 with at least mild deficits in strength and balance were selected from a r and om sample of enrollees in a health maintenance organization . The intervention was supervised exercise ( 1-h sessions , three per week , for 24 - 26 weeks ) , followed by self-supervised exercise . Exercise groups included strength training using weight machines ( n = 25 ) , endurance training using bicycles ( n = 25 ) , and strength and endurance training ( n = 25 ) . Study outcomes included gait tests , balance tests , physical health status measures , self-reported falls ( up to 25 months of follow-up ) , and inpatient and outpatient use and costs . RESULTS There were no effects of exercise on gait , balance , or physical health status . Exercise had a protective effect on risk of falling ( relative hazard = .53 , 95 % CI = .30-.91 ) . Between 7 and 18 months after r and omization , control subjects had more outpatient clinic visits ( p < .06 ) and were more likely to sustain hospital costs over $ 5000 ( p < .05 ) . CONCLUSIONS Exercise may have beneficial effects on fall rates and health care use in some subgroups of older adults . In community-living adults with mainly mild impairments in gait , balance , and physical health status , short-term exercise may not have a restorative effect on these impairments The purpose of the study was to determine whether resistance training ( RT ) or a combination of resistance and aerobic training ( CT ) result ed in the most improvement in measures of functional ability in functionally limited elders . Elderly adults who exhibited some limits in functional ability were r and omly assigned to either a CT , RT , or control ( C ) group . Both RT and CT exercised three times per week for 16 weeks . At Weeks 0 and 17 , participants completed six measures of strength and six functional tests . A 3 ( group ) x 3 ( time ) ANOVA with repeated measures on the time factor was used to analyze the results . CT and RT scored significantly better than C at Week 17 for biceps curl , elbow extension , chair st and , and time up the stairs . These findings demonstrate that RT and CT are both effective at increasing measures of strength and functional ability in elderly adults who begin exercise with functional limitations Background : It has been unclear which training mode is most effective and feasible for improving physical performance in the risk group of prefrail community-dwelling older adults . Objective : The purpose of the present study was to compare the effects of strength training ( ST ) versus power training ( PT ) on functional performance in prefrail older adults . This study was registered at clinical trials.gov as NCT00783159 . Methods : 69 community-dwelling older adults ( > 65 years ) who were prefrail according to the definition of Fried were included in a 12-week exercise program . The participants were r and omized into an ST group , a PT group and a control group . All participants were supplemented with vitamin D3 orally before entering the intervention period . The primary outcome was the global score on the Short Physical Performance Battery ( SPPB ) . Secondary outcomes were muscle power , appendicular lean mass ( aLM ) measured by dual energy X-ray absorptiometry and self-reported functional deficits ( Short Form of the Late-Life Function and Disability Instrument , SF-LLFDI ) . Results : Regarding changes in the SPPB score during the intervention , significant heterogeneity between the groups was observed ( p = 0.023 ) . In pair-wise comparisons , participants in both training groups significantly ( PT : p = 0.012 , ST : 0.009 ) increased their SPPB score ( PT : Δmean = 0.8 , ST : Δmean = 1.0 ) compared to the control group , with no statistical difference among training groups ( p = 0.301 ) . No statistical differences were found in changes in aLM ( p = 0.769 ) , muscle power ( p = 0.308 ) and SF-LLFDI ( p = 0.623 ) between the groups . Muscle power significantly increased ( p = 0.017 ) under vitamin D3 intake . Conclusions : In prefrail community-dwelling adults , PT is not superior to ST , although both training modes result ed in significant improvements in physical performance . With regard to dropout rates , ST appears to be advantageous compared to PT . The high prevalence of vitamin D3 deficiency and the slight improvement of physical performance under vitamin D3 supplementation among study participants underline the relevance of this approach in physical exercise interventions OBJECTIVES Although deficits in skeletal muscle strength , gait , balance , and oxygen uptake are potentially reversible causes of frailty , the efficacy of exercise in reversing frailty in community-dwelling older adults has not been proven . The aim of this study was to determine the effects of intensive exercise training ( ET ) on measures of physical frailty in older community-dwelling men and women . DESIGN R and omized controlled trial . SETTING Medical school research center . PARTICIPANTS One hundred fifteen sedentary men and women ( mean age + /- st and ard deviation = 83 + /- 4 ) with mild to moderate physical frailty , as defined by two of the following three criteria : Modified Physical Performance Test ( modified PPT ) score between 18 and 32 , peak oxygen uptake ( VO2 peak ) between 10 and 18 mL/kg/min , and self-report of difficulty or assistance with one basic activity of daily living ( ADL ) , or two instrumental ADLs . INTERVENTION Participants were r and omly assigned to a control group that performed a 9-month low-intensity home exercise program ( control ) or an exercise-training program ( ET ) . The control intervention primarily consisted of flexibility exercises . ET began with 3 months of flexibility , light-resistance , and balance training . During the next 3 months , resistance training was added , and , during the next 3 months , endurance training was added . MEASUREMENTS Modified PPT score , VO2 peak , performance of ADLs as measured by the Older Americans Re sources and Services instrument , and the Functional Status Question naire ( FSQ ) . RESULTS ET result ed in significantly greater improvements than home exercise in three of the four primary outcome measures . Adjusted 95 % confidence bounds on the magnitude of improvement in the ET group compared with the control group were 1.0 to 5.2 points for the modified PPT score , 0.9 to 3.6 mL/kg/min for VO2 peak , and 1.6 to 4.9 points for the FSQ score . CONCLUSIONS Our results show that intensive ET can improve measures of physical function and pre clinical disability in older adults who have impairments in physical performance and oxygen uptake and are not taking hormone replacement therapy better than a low-intensity home exercise program The purpose of the study was to compare the effects of three different types of group-based exercise programs ( resistance training , agility training and general stretching ) on back pain and health-related quality of life in older ( aged 75–85 years ) community-dwelling women with low bone mass ( i.e. , osteopenia or osteoporosis ) . The design was a 25-week r and omized controlled trial . Participating were 98 community-dwelling women with low bone mass between the ages of 75 to 85 years old . We assessed back pain and its related disability and health-related quality of life . All three types of group-based exercise programs significantly reduced back pain and its related disabilities , but only resistance and agility training significantly improved health-related quality of life in community-dwelling older women with low bone mass . Baseline physical activity level and class attendance were significant predictors of change in health-related quality of life . Change in back pain and its related disabilities after 25 weeks of exercise intervention was significantly correlated with change in health-related quality of life and changes in the domains of pain and physical function . Resistance and agility training significantly enhanced health-related quality of life and may have done so by increasing social interactions and support , enhancing self-efficacy of physical abilities and modifying the experience of back pain . These data provide valuable insight into the specifics of exercise prescription for older women with low bone mass . Future studies may wish to use individualized quality of life measures to further delineate the effects of different types of exercise on quality of life in older adults with low bone mass BACKGROUND AND PURPOSE Assessment of the quality of r and omized controlled trials ( RCTs ) is common practice in systematic review s. However , the reliability of data obtained with most quality assessment scales has not been established . This report describes 2 studies design ed to investigate the reliability of data obtained with the Physiotherapy Evidence Data base ( PEDro ) scale developed to rate the quality of RCTs evaluating physical therapist interventions . METHOD In the first study , 11 raters independently rated 25 RCTs r and omly selected from the PEDro data base . In the second study , 2 raters rated 120 RCTs r and omly selected from the PEDro data base , and disagreements were resolved by a third rater ; this generated a set of individual rater and consensus ratings . The process was repeated by independent raters to create a second set of individual and consensus ratings . Reliability of ratings of PEDro scale items was calculated using multirater kappas , and reliability of the total ( summed ) score was calculated using intraclass correlation coefficients ( ICC [ 1,1 ] ) . RESULTS The kappa value for each of the 11 items ranged from.36 to.80 for individual assessors and from.50 to.79 for consensus ratings generated by groups of 2 or 3 raters . The ICC for the total score was.56 ( 95 % confidence interval=.47-.65 ) for ratings by individuals , and the ICC for consensus ratings was.68 ( 95 % confidence interval=.57-.76 ) . DISCUSSION AND CONCLUSION The reliability of ratings of PEDro scale items varied from " fair " to " substantial , " and the reliability of the total PEDro score was " fair " to " good . Elderly participants experiencing difficulty in chair rising and with a maximum knee-extensor torque below 87.5 N . m were r and omized  to different versions of a strength-training program for the knee-extensors : to a high-guidance group ( HG ; two group sessions supervised by a physical therapist and one unsupervised home session per week , n = 17 ) , a medium-guidance group ( MG ; one supervised group session and two unsupervised home sessions per week , n = 16 ) , or a control group ( C ; no exercise , n = 16 ) . Maximal isometric knee strength increased more in HG than in C ( p = .03 ) and with increasing guidance ( p = .03 ) . The effect was mainly the result of participants with low initial strength . Walking speed increased more for HG than for C ( p = .02 ) and than for MG ( p = .06 ) . No statistically significant improvements were seen on other functional tests . In summary , the study shows a trend toward better results with more supervision , but more and larger studies are needed to confirm this OBJECTIVES To determine the effectiveness of vitamin D and home-based quadriceps resistance exercise on reducing falls and improving the physical health of frail older people after hospital discharge . DESIGN Multicenter , r and omized , controlled trial with a factorial design . SETTING Five hospitals in Auckl and , New Zeal and , and Sydney , Australia . PARTICIPANTS Two hundred forty-three frail older people . INTERVENTIONS Patients were r and omized to receive a single dose of vitamin D ( calciferol , 300,000 IU ) or placebo tablets and 10 weeks of high-intensity home-based quadriceps resistance exercise or frequency-matched visits . MEASUREMENTS The primary endpoints were physical health according to the short-form health survey at 3 months and falls over 6 months . Physical performance and self-rated function were secondary endpoints . Assessment s took place in the participants ' homes at 3 and 6 months after r and omization and were performed by blinded assessors . RESULTS There was no effect of either intervention on physical health or falls , but patients in the exercise group were at increased risk of musculoskeletal injury ( risk ratio = 3.6 , 95 % confidence interval = 1.5 - 8.0 ) . Vitamin D supplementation did not improve physical performance , even in those who were vitamin D deficient ( < 12 ng/mL ) at baseline . CONCLUSION Neither vitamin D supplementation nor a home-based program of high-intensity quadriceps resistance exercise improved rehabilitation outcomes in frail older people after hospitalization . There was no effect of vitamin D on physical performance , and the exercises increased the risk of musculoskeletal injury . These findings do not support the routine use of these interventions at these dosages in the rehabilitation of frail older people Background and aims : An acute illness may place older frail people at increased risk of losing independence in functional abilities . Physical exercise may reduce the risk by improving muscle strength and balance . However , the effects of physical training on functional abilities have not been studied among frail , very old people recovering from an acute illness . The aim of this study was to determine the effects of a group-based exercise program on their ability to carry out self-care ( ADL ) and instrumental activities ( IADL ) relevant to daily life after discharge from hospital . Methods : This r and omized controlled trial examined 68 community-dwelling women aged 75 years or older ( mean age 83.0 , SD 3.9 ) who were hospitalized due to an acute illness , and were mobility-impaired at admission . Participants were recruited from the geriatric ward of a primary -care health-center hospital , and were r and omized into group-based strength training ( n=34 ) and control ( n=34 ) groups . The 10-week group-based intervention included strength training and functional exercises . The control group received instructions for a home exercise training program , including functional exercises but no further encouragement to exercise . The level of independence in ADL and IADL was evaluated , using a 13-item scale with stepwise grading from fully independent to fully dependent . Measurements took place immediately before and after the intervention , and three and nine months later . Results : The intervention did not have any significant main effect ( p=0.407 ) , nor was there any significant interaction between follow-up time and intervention ( p=0.854 ) . Conclusions : The multi-component outpatient strength training program did not improve autonomy in expert-evaluated ADL/IADL functions A systematic review of r and omised controlled trials was undertaken to evaluate the effectiveness of  workplace interventions  to prevent low back pain .  Potential trials were located by a computerised search supplemented with citation tracking . The method ological quality of the trials was assessed on 11 criteria and the level of evidence for each intervention was determined , based upon the amount , consistency and quality of evidence from the trials . The review located 13 trials that were generally of moderate quality . The trials suggest that work place exercise is effective , braces and education are ineffective , and workplace modification plus education is of unknown value in preventing low back pain BACKGROUND / OBJECTIVES To test the effects of Strong for Life ( SFL ) on the physical performance and self-rated health of older adults receiving Home and Community-Based Services ( HCBS ) . DESIGN R and omized , two-group trial with pre-post measures . SETTING In-home exercise program . PARTICIPANTS Clients aged 65 - 95 ( n=42 ) and their Home Care Aide ( HCA ) ( n=32 ) were r and omly assigned to a usual care and SFL intervention or usual care control group . INTERVENTION Clients were instructed in SFL by their HCA and completed SFL 3 times per week for 12-weeks . MEASUREMENTS Outcomes included grip and quadriceps strength , Timed Up and Go , gait speed , Self-Efficacy for Exercise , pain , and PROMIS-global health measured at baseline and immediately following the intervention . Clients completed opened ended survey items on SFL program evaluation . RESULTS Effect sizes were moderate for grip strength ( d= .38 ) , pain ( d= .34 ) , and PROMIS-global health ( d= .27 ) . Small effect sizes were found for all other measures . Median quadriceps and TUG scores differentially improved among intervention participants versus controls . No adverse health events and high program satisfaction were reported . Frailty prevalence in the control group increased between baseline and post-test while frailty prevalence in the intervention group decreased during the same time period . CONCLUSION Strong for Life has the potential to improve the strength , mobility , health , and frailty of older adults receiving HCBS . This study provides initial evidence of the impact of SFL for older adults receiving HCBS , as well as the safety of the intervention evidence d by the lack of reported adverse events BACKGROUND AND PURPOSE The majority of patients after a hip fracture do not return to prefracture functional status . Depression has been shown to affect recovery . Although exercise can reduce impairments , access issues limit elderly people from participating in facility-based programs . The primary purpose of this study was to determine the effects and feasibility of a home exercise program of moderate- or high-intensity exercise . A secondary purpose was to explore the relationship of depression and physical recovery . SUBJECTS Thirty-three elderly people ( 24 women , 9 men ; mean = 78.6 years of age , SD = 6.8 , range = 64 - 89 ) who had completed a regimen of physical therapy following hip fracture participated in the study . Subjects were r and omly assigned to a resistance training group , an aerobic training group , or a control group . METHODS Subjects were tested before and upon completion of the exercise trial . Isometric lower-extremity force , 6-minute-walk distance , free gait speed , mental status , and physical function were measured . Each exercise session was supervised by a physical therapist , and subjects received 20 visits over 12 weeks . The control group received biweekly mailings . The resistance training group performed 3 sets of 8 repetitions at the 8-repetition maximum intensity using a portable progressive resistance exercise machine . The aerobic training group performed activities that increased heart rate 65 % to 75 % of their age-predicted maximum for 20 continuous minutes . RESULTS Resistance and aerobic training were performed without apparent adverse effects , and adherence was 98 % . All groups improved in distance walked , force produced , gait speed , and physical function . Isometric force improved to a greater extent in the intervention groups than in the control group . Depressive symptoms interacted with treatment group in explaining the outcomes of 6-minute-walk distance and gait speed . DISCUSSION AND CONCLUSION High-intensity exercise performed in the home is feasible for people with hip fracture . Larger sample sizes may be necessary to determine whether the exercise regimen is effective in reducing impairments and improving function . Depression may play a role in the level of improvement attained OBJECTIVES To evaluate the short-term effects of three different resistance training programs , conducted at low intensity , on physical performance , muscle cross-sectional area ( CSA ) and the capacity to perform daily tasks in older adults living in a geriatric nursing home . DESIGN R and omized controlled trial , with a 4-month intervention period . SETTING A geriatric nursing home in Valencia , Spain . PARTICIPANTS Eighty-nine adults aged 75 to 96 who were independent in their daily activities . INTERVENTION After a baseline assessment , the participants were r and omly assigned to the control group or one of the three intervention groups : volitional contraction ( VC ; n=22 ) , neuromuscular electrical stimulation ( NMES ; n=22 ) , or neuromuscular electrical stimulation superimposed onto voluntary contractions ( NMES+ ; n=22 ) . The intervention focused on knee extension exercises and its intensity was set at 40 % of one-repetition maximum ( 1RM ) . MEASUREMENTS The primary outcome measure was mobility . Secondary outcomes were rectus femoris CSA , balance , aerobic endurance , upper-body strength and the capacity to perform daily tasks . All data were collected at baseline and after the 4-month intervention period . RESULTS The two-way ANOVA analysis showed a significant group × time interaction effect for the mobility ( P=.022 ) , rectus femoris CSA ( P=.001 ) , and the capacity to perform daily tasks ( P=.05 ) . The within-group analysis found a more prominent effect in the NMES+ group . Significant improvements were seen in rectus femoris CSA and the capacity to perform daily tasks in all intervention groups . Mobility only improved in the NMES+ group ( P=.026 ) . CONCLUSION From a short-term perspective , NMES+ exercise training , performed at low intensity , can improve physical performance , muscle CSA , and the capacity to perform daily activities , and to partially mitigate age-related consequences in older adults BACKGROUND Strength loss is strongly associated with functional decline and is reversible with exercise . The effect of increased strength on function has not been clearly established . The purpose of this study was to determine whether strength gain is associated with improvement in physical performance and disability . METHODS One hundred functionally impaired community-dwelling men and women ( 77.6 + /- 7.6 yrs ) were tested at baseline and outcome for lower extremity strength , physical performance , and disability . After r and om group assignment , exercise participants received strengthening exercises in their homes three times a week for 10 weeks while control subjects continued their normal activities . Using multiple regression techniques , the relationship between strength gain and improvement in physical performance and disability was assessed , controlling for age , depression , and baseline strength . RESULTS A significant impact of strength gain on mobility skills ( p = .0009 ) was found . The impact of strength gain on chair rise performance was significant in participants who were more impaired ( p = .04 ) . Strength gain was associated with gain in gait speed ( p = .02 ) and in falls efficacy ( p = .05 ) , but not with other balance , endurance , or disability measures . CONCLUSIONS Lower extremity strength gain is associated with gains in chair rise performance , gait speed , and in mobility tasks such as gait , transfers , stooping , and stair climbing , but not with improved endurance , balance , or disability . Strength gain is also associated with improvement in confidence in mobility . Factors that may influence the ability of strength gain to affect function are initial level of frailty and specificity of exercise . These results support the idea that strength training is an intervention that can potentially improve physical health status in many frail elders OBJECTIVE To evaluate the effectiveness of three different training protocol s on physical function of older adults living in long-term care facilities . Emphasis was placed on feasibility in real-life situations . METHODS Subjects ( N=224 ) were r and omised to 6 months of twice weekly ( 1 ) resistance training ; ( 2 ) all-round functional-skills training ; ( 3 ) a combination of both ; or ( 4 ) a control program .  Fitness and performance measures and self-reported disability were measured at baseline and after 24 weeks intervention . RESULTS Attendance to the strength training was 76 % , to the functional-skills training 70 % and to the combined training 73 % . In those who attended at least 75 % of all classes ( n=97 ) the functional-skills and combined training program improved several fitness and performance measures compared to the control group . CONCLUSION Twice weekly functional-skills training , or a combination of resistance and functional-skills training can improve several fitness and performance measures of institutionalised older people . PRACTICE IMPLICATION S An important finding from our study was that less than twice a week exercise training is not enough for functional improvement , while it proved difficult for the elderly subjects to exercise twice weekly . Education on the health benefits of regular exercise , and a larger availability of classes in long-term care facilities may improve attendance
target: Conclusions This review provides evidence that RT has a moderate positive effect on self-reported disability/function  in old people with or at risk for disability .
  The effects are strongly associated with effects on objective measures of lower body functional capacity
background: Background Self-reported disability has a strong negative impact on older people ’s  quality of life and is often associated with the need for assistance and health care services .
  Resistance training ( RT ) has been repeatedly shown to improve muscle function ( e.g. strength ) and functional capacity ( e.g. gait speed , chair-rise ) in older adults with functional limitations .
  Nevertheless , it is unclear whether such objective ly assessed improvements translate into a reduction in self-reported disability .
  Objectives To assess : i ) whether and to what extent RT interventions have an effect on self-reported disability in older adults ( ≥65 years ) with functional limitations or disability ; and ii ) whether the effects on self-reported disability are associated with changes in objective measures of muscle strength and functional capacity across studies .
