To compare 2 exercise modalities, aerobic fitness training and stretching exercises, in patients with fibromyalgia (FM) in relation to function, pain, quality of life, depression, and anxiety, and to correlate the cardiorespiratory fitness gain with symptom improvement.
                Seventy-six women with FM between 18 and 60 years old were randomized to either an aerobic program or stretching program, for 20 weeks. They were evaluated at the beginning of the program and after 10 and 20 weeks in relation to the improvement of aerobic fitness, flexibility, function, Fibromyalgia Impact Questionnaire (FIQ), Short-form Health Survey (SF-36), and depression and anxiety levels. Ventilatory anaerobic threshold (VT) and maximum oxygen uptake (VO2max) were determined by expired gas analyses.
                Aerobic exercise was superior to stretching in relation to VO2 max, VT, function, depression, pain, and the emotional aspects and mental health domains of SF-36. Patients in the stretching group showed no improvement in depression, "role emotional," and "mental health." No association was noted between improvement in aerobic fitness as measured by VT and the improvement of pain, function, or scores in FIQ and SF-36.
                Our results confirm that aerobic exercise is beneficial to patients with FM, but the cardiorespiratory fitness gain is not related to improvement of FM symptoms. To examine the effectiveness of a supervised aerobic exercise program, a self-management education program, and the combination of exercise and education for women with fibromyalgia (FM).
                One hundred fifty-two women were randomized into one of 4 groups: exercise-only, education-only, exercise and education, or control. The duration of the study was 12 weeks. All subjects were analyzed at 3 times: before study, immediately upon completion, and 3 months after completion of the intervention program on measures of disability, self-efficacy, fitness, tender point count, and tender point tenderness. Of the 152 women, complete data were available for 95 and 69 who complied with the protocol. In order to determine the group time interaction, a 2 way analysis of variance with repeated measures was used for each measure.
                The only significant group time interaction was reported with the compliance analysis for the Self-Efficacy Coping with Other Symptoms subscale and the Six Minute Walk. If the program was followed, the combination of a supervised exercise program and group education provided persons with FM with a better sense of control over their symptoms. Fitness improved in the 2 groups undergoing supervised aerobic exercise programs. However, the improvement in fitness was maintained at followup in the exercise-only group and not the combined group. Conclusion. Subjects receiving the combination of exercise and education and who complied with the treatment protocol improved their perceived ability to cope with other symptoms. In addition, a supervised exercise program increased walking distance at post-test, an increase that was maintained at followup in the exercise-only group. Results demonstrate the challenges with conducting exercise and education studies in persons with FM. To investigate the effects of 21 weeks' progressive strength training on neuromuscular function and subjectively perceived symptoms in premenopausal women with fibromyalgia (FM).
                Twenty one women with FM were randomly assigned to experimental (FM(T)) or control (FM(C)) groups. Twelve healthy women served as training controls (H(T)). The FM(T) and H(T) groups carried out progressive strength training twice a week for 21 weeks. The major outcome measures were muscle strength and electromyographic (EMG) recordings. Secondary outcome measures were pain, sleep, fatigue, physical function capacity (Stanford Health Assessment Questionnaire), and mood (short version of Beck's depression index).
                Female FM(T) subjects increased their maximal and explosive strength and EMG activity to the same extent as the H(T) group. Moreover, the progressive strength training showed immediate benefits on subjectively perceived fatigue, depression, and neck pain of training patients with FM.
                The strength training data indicate comparable trainability of the neuromuscular system of women with FM and healthy women. Progressive strength training can safely be used in the treatment of FM to decrease the impact of the syndrome on the neuromuscular system, perceived symptoms, and functional capacity. These results confirm the opinion that FM syndrome has a central rather than a peripheral or muscular basis. To investigate the effects of strength training on neuromuscular functions in elderly females with fibromyalgia (FM).
                Thirteen females with fibromyalgia [group FMt; mean age (s.d.) 60.2 (2.5) years] and 11 healthy controls [group HCt; 64.2 (2.7) yr] carried out supervised strength training twice a week for 21 weeks. Thirteen FM patients [group FMc; 59.1 (3.5) yr] served as non-training controls. Maximal isometric force and electromyographic (EMG) activity of the right quadriceps femoris in knee extension and flexion actions, maximal 10-m walking speed, and 10-step stair-climbing time were measured. Tender points were assessed by palpation, subjectively perceived symptoms with a visual analogue scale, and the self-reported physical function capacity by Health Assessment Questionnaire (HAQ).
                The mean (s.d.) increases in maximal extension force during the training period in groups FMt and in HCt were 32 (33)% (P < 0.001) and 24 (12)% (P < 0.001) respectively and those of flexion were 13 (20)% (P < 0.05) and 24 (17)% (P < 0.01). Explosive force of the extensors increased in both FMt and in HCt. The integrated EMGs of the vastus lateralis and medialis muscles increased in both FMt and HCt. Muscle forces and EMGs in group FMc remained at the basal level. Walking speed, stair-climbing time and the HAQ index improved in group FMt. The changes in the number of tender points and in perceived symptoms were in favour of the training group FMt.
                The data support the hypothesis that elderly female FM patients have normal neuromuscular function. Supervised strength training also suits elderly FM patients, has positive effects on perceived symptoms and improves functional capacity without complications. To assess the utility of an exercise program, which included aerobic, flexibility and strengthening elements, in the treatment of fibromyalgia (FM). FM is a chronic musculoskeletal condition characterized by diffuse musculoskeletal pain and aching. It has been suggested that aerobic exercise is helpful in its treatment.
                We studied 60 patients who met American College of Rheumatology criteria for FM and had no significant comorbidities. Measurements performed on each patient at the pre and poststudy assessment included the number of tender points (TP), total myalgic scores (TM), aerobic fitness (AF), flexibility and isokinetic strength. After initial evaluation patients were randomly assigned to either an exercise or a relaxation group. Each group met 3 times per week for 6 weeks for 1 h of supervised exercise or relaxation. All patients data were stored in a computerized database and statistical analysis was performed on all pre and poststudy assessments.
                Thirty-eight patients (18 exercise and 20 relaxation) completed the study. Analysis of our data showed no significant difference between the groups in their prestudy assessment. Poststudy assessments, however, showed a significant improvement between the exercise and relaxation groups in TP (p < 0.05), TM (p < 0.05), and AF (p < 0.05). Similar improvements were also found when the pre and poststudy assessment of the exercise group were compared.
                Exercise is helpful in the management of FM in the short term. It also shows that FM patients can undertake an exercise program which includes aerobic, flexibility, and strength training exercises without adverse effects. The long term utility of this type of exercise requires further evaluation. Cancer-related fatigue is the most disabling symptom experienced by breast cancer patients following the cancer treatment. The positive effects of physical activity in the rehabilitation of breast cancer patients are documented in several studies. In a randomized controlled study the effects of a structured physical training program on fatigue and health-related quality of life were evaluated.
                63 breast cancer patients with cancer-related chronic fatigue were randomized at the beginning of the inpatient rehabilitation. The control group received the standard complex rehabilitation program, the intervention group a structured physical training program and additional muscle strength and aerobic exercises. The effects of the treatment were evaluated by questionnaires at the start of rehabilitation (t1), end of rehabilitation (t2), and 3 months after t2 (t3). Isometric muscle strength and aerobic capacity were evaluated at t1 and t2.
                There was an improvement of muscle strength at the end of rehabilitation for both groups. The increase from t1 to t2 was significantly higher for the training group. The scores for global quality of life, physical well-being, and functionality increased from t1 to t2, but further improvement in the follow-up (t3) was only observed in the training group. The cancer-related fatigue was significantly reduced in the training group from t1 to t3, however, not in the control group.
                Structured physical training programs initiated during inpatient rehabilitation and continuously practiced in the time thereafter can improve symptoms of chronic fatigue and quality of life in breast cancer patients. To compare the therapeutic effects of physical fitness training or biofeedback training with the results of usual care in patients with fibromyalgia (FM).
                One hundred forty-three female patients with FM (American College of Rheumatology criteria) were randomized into 3 groups: a fitness program (n = 58), biofeedback training (n = 56), or controls (n = 29). Half the patients in the active treatment groups also received an educational program aimed at improving compliance. Assessments were done at baseline and after 24 weeks. The primary outcome was pain [visual analog scale (VAS)]. Other endpoints were the number of tender points, total myalgic score (dolorimetry), physical fitness, functional ability (Arthritis Impact Measurement Scale and Sickness Impact Profile), psychological distress (Symptom Checklist-90-Revised), patient global assessment (5 point scale), and general fatigue (VAS).
                Baseline scores were similar in all 3 groups. Altogether 25 (17.5%) patients dropped out; they were similarly distributed over all groups: 14 patients after randomization and 11 (8%) during the study. A true high impact level for fitness training was not attained by any patient. After treatment, no significant differences in change scores of any outcome were found between the groups (ANOVA, p > 0.05). All outcome measures showed large variations intra- and interindividually. The educational program did not result in higher compliance with training sessions (62% vs 71%). Analysis of the subgroup of subjects with a high attendance rate (> 67%) also showed no improvement.
                In terms of training intensity and maximal heart rates, the high impact fitness intervention had a low impact benefit. Therefore effectiveness of high impact physical fitness training cannot be demonstrated. Thus compared to usual care, the fitness training (i.e., low impact) and biofeedback training had no clear beneficial effects on objective or subjective patient outcomes in patients with FM. An experiment was conducted to determine whether aerobic exercise training or relaxation training would be effective for reducing the deleterious effects of life stress on physical and psychologic health. Over 1000 college students were surveyed, and 55 of those who reported experiencing a high number of negative life events over the preceding year were assigned to an aerobic exercise training condition, a relaxation training condition, or a no-treatment control condition. Physical and psychologic health were assessed with self-report measures before, halfway through, immediately following, and 8 weeks after the 11-week training (and control) period. Heart rate data collected during a treadmill test indicated that the aerobic exercise training was effective for improving cardiovascular fitness. Psychologic measures indicated that the exercise training condition was more effective than the other two conditions for reducing depression during the first 5 weeks of training. No differences were found among the conditions on self-report measures of physical health. These findings suggest that aerobic exercise training may be useful for reducing the severity and duration of depressive reactions following stressful life change. To test the efficacy of a graded aerobic exercise programme in the chronic fatigue syndrome.
                Randomised controlled trial with control treatment crossover after the first follow up examination.
                Chronic fatigue clinic in a general hospital department of psychiatry.
                66 patients with the chronic fatigue syndrome who had neither a psychiatric disorder nor appreciable sleep disturbance.
                Random allocation to 12 weeks of either graded aerobic exercise or flexibility exercises and relaxation therapy. Patients who completed the flexibility programme were invited to cross over to the exercise programme afterwards.
                The self rated clinical global impression change score, "very much better" or "much better" being considered as clinically important.
                Four patients receiving exercise and three receiving flexibility treatment dropped out before completion. 15 of 29 patients rated themselves as better after completing exercise treatment compared with eight of 30 patients who completed flexibility treatment. Analysis by intention to treat gave similar results (17/33 v 9/33 patients better). Fatigue, functional capacity, and fitness were significantly better after exercise than after flexibility treatment. 12 of 22 patients who crossed over to exercise after flexibility treatment rated themselves as better after completing exercise treatment 32 of 47 patients rated themselves as better three months after completing supervised exercise treatment 35 of 47 patients rated themselves as better one year after completing supervised exercise treatment.
                These findings support the use of appropriately prescribed graded aerobic exercise in the management of patients with the chronic fatigue syndrome. To examine the impact of fitness training with recently brain-injured inpatients on exercise capacity and functional and psychologic outcome measures.
                A randomized controlled trial of exercise versus relaxation training for 3 months. Blind assessments were conducted before and after the end of a 12-week training program, as well as at follow-up assessment 12 weeks posttraining.
                Four regional neurologic inpatient rehabilitation units.
                Of 157 patients recruited 24 +/- 14 weeks after single-incident brain injury, 142 patients were assessed at week 12, and 128 patients at follow-up.
                Patients were randomized between cycle ergometer aerobic training and a relaxation training control condition, which was theoretically inert with respect to cardiovascular fitness.
                Validation of exercise training (peak work rate, peak heart rate, body mass index); mobility and physical function (modified Ashworth scale, Berg balance scale, Rivermead Mobility Index, 10-m walk velocity); disability and dependency (Barthel index, FIMtrade mark instrument, Nottingham Extended Activities of Daily Living); and psychologic function (fatigue questionnaire, Hospital Anxiety and Depression Scale).
                Significant improvements in exercise capacity (p <.05) in the exercise training group (n = 70) relative to the control group (n = 72) were not matched by greater improvements in functional independence, mobility, or psychologic function, at either 12 weeks or follow-up.
                The benefits of improved cardiovascular fitness did not appear to extend to measurable change in function or psychologic state. Fibromyalgia (FM), a rheumatological disorder of unknown origin, is characterized by both physical and psychological symptoms. Although inconclusive results have been reported for most treatment modalities, exercise appears to have universal support for decreasing the myriad of symptoms associated with FM. Weaknesses in the literature, however, prevent conclusive statements regarding exercise prescription and concomitant impact on FM symptomology.
                The current pilot study attempted to examine the effect of a 24-wk walking program at predetermined intensities on FM.
                Initial design was a randomized control trial with high- and low-intensity exercise groups, and a control group. Subsequent nonrandomized control trials were based on actual exercise behavior.
                No differences between initial groups were identified. By collapsing groups, heart rate (HR) decreased (P < 0.05) weeks 0-12. Functional impairments were reduced 54% weeks 0-24, with exercise having a large impact (omega2 = 0.30) on this decrease. By reassigning groups, impact of FM on current health status decreased in the low-intensity group (P < 0.05) and increased in the high-intensity group (P < 0.02) weeks 0-24. Omega squared indicated strong influence of exercise on pain (omega2 = 0.51), with greater pain in the high-intensity group.
                A larger number of subjects and direct supervision of the training program to increase compliance is necessary to clarify the effects of a walking program on the manifestations of FM. Results indicate that intensity of the walking program is an important consideration. Individuals with FM can adhere to low-intensity walking programs two to three times per week, possibly reducing FM impact on daily activities. This pilot study examined whether exercise as an adjunctive rehabilitation therapy could benefit women who have early stage breast cancer and are currently receiving chemotherapy/radiotherapy. The study was designed as a randomised controlled trial (RCT). Physical functioning, fatigue and Quality of Life (QoL) outcomes were evaluated pre and post a 12-week intervention. The results showed that after 12 weeks the women who participated in the exercise programme (n = 12) displayed significantly higher levels of physical functioning and reported higher QoL scores than the controls (n = 10). Changes in fatigue and satisfaction with life favoured the intervention group but did not reach significance. These results are encouraging and suggest that a structured group exercise programme during adjuvant treatment is a safe, well tolerated and effective way of providing physical and psychological health benefits to women during treatment for early stage breast cancer. Since this was a pilot study the numbers did not allow appropriately powered analyses of some variables of interest and favoured relatively young and socio-economically advantaged women. Future studies need to address these issues and determine if these short-term benefits can be sustained. The cardiovascular and behavioral adaptations associated with a 4-month program of aerobic exercise training were examined in 101 older men and women (mean age = 67 years). Subjects were randomly assigned to an Aerobic Exercise group, a Yoga and Flexibility control group, or a Waiting List control group. Prior to and following the 4-month program, subjects underwent comprehensive physiological and psychological evaluations. Physiological measures included measurement of blood pressure, lipids, bone density, and cardiorespiratory fitness including direct measurements of peak oxygen consumption (VO2) and anaerobic threshold. Psychological measures included measures of mood, psychiatric symptoms, and neuropsychological functioning. This study demonstrated that 4 months of aerobic exercise training produced an overall 11.6% improvement in peak VO2 and a 13% increase in anaerobic threshold. In contrast, the Yoga and Waiting List control groups experienced no change in cardiorespiratory fitness. Other favorable physiological changes observed among aerobic exercise participants included lower cholesterol levels, diastolic blood pressure levels, and for subjects at risk for bone fracture, a trend toward an increase in bone mineral content. Although few significant psychological changes could be attributed to aerobic exercise training, participants in the two active treatment groups perceived themselves as improving on a number of psychological and behavioral dimensions. To determine the effectiveness of self-management education and physical training in decreasing fibromyalgia (FMS) symptoms and increasing physical and psychological well being.
                A pretest-posttest control group design was used. Ninety-nine women with FMS were randomly assigned to 1 of 3 groups; 86 completed the study. The education only group received a 6-week self-management course. The education plus physical training group received the course and 6 h of training designed to assist them to exercise independently. The control group got treatment after 3 months.
                The experimental programs had a significant positive impact on quality of life and self-efficacy. Helplessness, number of days feeling bad, physical dysfunction, and pain in the tender points decreased significantly in one or both of the treated groups when retested 6 weeks after the end of the program. Longterm followup of 67 treated subjects showed significant positive changes on the Fibromyalgia Impact Questionnaire primarily in the physical training group. Among all subjects, 87% were exercising at least 3 times/week for 20 min or more; 46% said they had increased their exercise level since participating in the program; 70% were practicing relaxation strategies as needed; 46% were working at least half time as opposed to 37% at pretest.
                Self-efficacy of the treated groups was enhanced significantly by the program. Other changes were smaller and more delayed than had been expected. Recommendations for future trials include a longer education program, more vigorous physical training, and longterm followup. Fifty-four multiple sclerosis (MS) patients were randomly assigned to exercise (EX) or nonexercise (NEX) groups. Before and after 15 weeks of aerobic training, aspects of fitness including maximal aerobic capacity (VO2max), isometric strength, body composition, and blood lipids were measured. Daily activities, mood, fatigue, and disease status were measured by the Profile of Mood States (POMS), Sickness Impact Profile (SIP), Fatigue Severity Scale (FSS), and neurological examination. Training consisted of 3 x 40-minute sessions per week of combined arm and leg ergometry. Expanded Disability Status Scale (EDSS) scores were unchanged, except for improved bowel and bladder function in the EX group. Compared with baseline, the EX group demonstrated significant increases in VO2max, upper and lower extremity strength, and significant decreases in skinfolds, triglyceride, and very-low-density lipoprotein (VLDL). For the EX group, POMS depression and anger scores were significantly reduced at weeks 5 and 10, and fatigue was reduced at week 10. The EX group improved significantly on all components of the physical dimension of the SIP and showed significant improvements for social interaction, emotional behavior, home management, total SIP score, and recreation and past times. No changes were observed for EX or NEX groups on the FSS. Exercise training resulted in improved fitness and had a positive impact on factors related to quality of life. Previous observational and interventional studies have suggested that regular physical exercise may be associated with reduced symptoms of depression. However, the extent to which exercise training may reduce depressive symptoms in older patients with major depressive disorder (MDD) has not been systematically evaluated.
                To assess the effectiveness of an aerobic exercise program compared with standard medication (ie, antidepressants) for treatment of MDD in older patients, we conducted a 16-week randomized controlled trial.
                One hundred fifty-six men and women with MDD (age, > or = 50 years) were assigned randomly to a program of aerobic exercise, antidepressants (sertraline hydrochloride), or combined exercise and medication. Subjects underwent comprehensive evaluations of depression, including the presence and severity of MDD using Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria and Hamilton Rating Scale for Depression (HAM-D) and Beck Depression Inventory (BDI) scores before and after treatment. Secondary outcome measures included aerobic capacity, life satisfaction, self-esteem, anxiety, and dysfunctional cognitions.
                After 16 weeks of treatment, the groups did not differ statistically on HAM-D or BDI scores (P = .67); adjustment for baseline levels of depression yielded an essentially identical result. Growth curve models revealed that all groups exhibited statistically and clinically significant reductions on HAM-D and BDI scores. However, patients receiving medication alone exhibited the fastest initial response; among patients receiving combination therapy, those with less severe depressive symptoms initially showed a more rapid response than those with initially more severe depressive symptoms.
                An exercise training program may be considered an alternative to antidepressants for treatment of depression in older persons. Although antidepressants may facilitate a more rapid initial therapeutic response than exercise, after 16 weeks of treatment exercise was equally effective in reducing depression among patients with MDD. The treatment of patients with fibromyalgia (FM), a high-prevalence chronic pain condition with a high impact on both patients and society, poses a great challenge to clinicians due to a lack of effective treatments. In view of the large individual variability in outcome, selecting patients at risk of long-term dysfunction and offering tailored treatment may be promising for beneficial treatment effects.
                High-risk patients were selected and classified into 2 groups (pain-persistence and pain-avoidance groups) and subsequently randomized in groups to either a treatment condition (TC) or a waiting list control condition (WLC). Treatment consisted of 16 sessions of cognitive-behavioral therapy (CBT) and exercise training in groups, tailored to the patient's specific cognitive-behavioral pattern, delivered within 10 weeks. Physical and psychological functioning and impact of FM were assessed at baseline, posttreatment, and 6-month followup. Treatment effects were evaluated using a linear mixed model.
                The treatment effects were significant for all primary outcomes, showing significant differences in physical (pain, fatigue, and functional disability) and psychological (negative mood and anxiety) functioning, and impact of FM for the TC in comparison with the WLC. Effect sizes in the TC were overall large, and reliable change indices indicated a clinically relevant improvement among the TC.
                The presented results demonstrate for the first time that tailored CBT and exercise training for high-risk patients with FM is effective in improving short- and long-term physical and psychological functioning, indicating that tailoring treatment is likely to promote beneficial outcomes in FM and reduce the burden for patients and society. To assess the benefit and harm of exercise training in adults with clinical depression.
                The DEMO trial is a randomized pragmatic trial for patients with unipolar depression conducted from January 2005 through July 2007. Patients were referred from general practitioners or psychiatrists and were eligible if they fulfilled the International Classification of Diseases, Tenth Revision, criteria for unipolar depression and were aged between 18 and 55 years. Patients (N = 165) were allocated to supervised strength, aerobic, or relaxation training during a 4-month period. The primary outcome measure was the 17-item Hamilton Rating Scale for Depression (HAM-D(17)), the secondary outcome measure was the percentage of days absent from work during the last 10 working days, and the tertiary outcome measure was effect on cognitive abilities.
                At 4 months, the strength measured by 1 repetition maximum for chest press increased by a mean (95% CI) of 4.0 kg (0.8 to 7.2; p = .014) in the strength training group versus the relaxation group, and maximal oxygen uptake increased by 2.7 mL/kg/min (1.2 to 4.3; p = .001) in the aerobic group versus the relaxation group. At 4 months, the mean change in HAM-D(17) score was -1.3 (-3.7 to 1.2; p = .3) and 0.4 (-2.0 to 2.9; p = .3) for the strength and aerobic groups versus the relaxation group. At 12 months, the mean differences in HAM-D(17) score were -0.2 (-2.7 to 2.3; p = .8) and 0.6 (-1.9 to 3.1; p = .6) for the strength and aerobic groups versus the relaxation group. At 12 months, the mean differences in absence from work were -12.1% (-21.1% to -3.1%; p = .009) and -2.7% (-11.7% to 6.2%; p = .5) for the strength and aerobic groups versus the relaxation group. No statistically significant effect on cognitive abilities was found.
                Our findings do not support a biologically mediated effect of exercise on symptom severity in depressed patients, but they do support a beneficial effect of strength training on work capacity.

                Copyright 2009 Physicians Postgraduate Press, Inc. To determine the effectiveness of a muscle strengthening program compared to a stretching program in women with fibromyalgia (FM).
                Sixty-eight women with FM were randomly assigned to a 12 week, twice weekly exercise program consisting of either muscle strengthening or stretching. Outcome measures included muscle strength (main outcome variable), flexibility, weight, body fat, tender point count, and disease and symptom severity scales.
                No statistically significant differences between groups were found on independent t tests. Paired t tests revealed twice the number of significant improvements in the strengthening group compared to the stretching group. Effect size scores indicated that the magnitude of change was generally greater in the strengthening group than the stretching group.
                Patients with FM can engage in a specially tailored muscle strengthening program and experience an improvement in overall disease activity, without a significant exercise induced flare in pain. Flexibility training alone also results in overall improvements, albeit of a lesser degree. To compare a supervised 12-week aerobic exercise class with unsupervised home aerobic exercises in the treatment of patients with fibromyalgia.
                This was a 48-week randomized single (observer) blind study in a teaching hospital rheumatology and physiotherapy department. The subjects were 74 patients who fulfilled the American College of Rheumatology criteria for fibromyalgia. Results and conclusions. A 12-week exercise class programme with home exercises demonstrated no benefit over a single physiotherapy session with home exercises in the treatment of pain in patients with fibromyalgia. Neither group (nor the groups combined) showed an improvement in pain compared with baseline. There was some significant benefit in psychological well-being in the exercise class group and perhaps a slowing of functional deterioration in this group. The aim of this study was to compare aerobic and resistance training in children with cystic fibrosis (CF) admitted to hospital with an intercurrent pulmonary infection with a control group. The subjects were randomized into three groups on the first day of admission. The fat-free mass (FFM) was calculated, using the skin fold thickness from four sites (biceps, triceps, subscapular, and iliac crest). Pulmonary function tests were performed within 36 hr of admission and repeated on discharge from the hospital, and again at 1 month after discharge. All subjects performed an incremental treadmill exercise test, using a modified Bruce protocol. Lower limb strength was measured using a Cybex dynamometer. An assessment of quality of life was made using the Quality of Well Being Scale, as previously reported. Activity levels were measured using a 7-day activity diary, and subjects also wore an accelerometer on their hips. There were no significant differences between the three groups in terms of disease severity, and length of stay in hospital. Subjects in all three groups received intravenous antibiotics and nutritional supplementation as determined by the physician. Children randomized to the aerobic training group participated in aerobic activities for five sessions, each of 30-min duration, a week. The children randomized to the resistance training group exercised both upper and lower limbs against a graded resistance machine. Subjects in the control group received standard chest physiotherapy. Our study demonstrated that children who received aerobic training had significantly better peak aerobic capacity, activity levels, and quality of life than children who received the resistance training program. Children who received resistance training had better weight gain (total mass, as well as fat-free mass), lung function, and leg strength than children who received aerobic training. A combination of aerobic and resistance training may be the best training program, and future studies to assess optimal training programs for CF patients are indicated.
                Copyright 2002 Wiley-Liss, Inc. Multiple sclerosis (MS) patients of an inpatient rehabilitation program have been randomly assigned to an exercise training (MS-ET) or nontraining group (MS-NI). Before and after 4 weeks of aerobic exercise training, a graded maximal exercise test with measurement of gas exchange and a lung function test was administered to all 26 patients fulfilling the inclusion criteria. Activity level, fatigue and health perception were measured by means of questionnaires. Twenty-six healthy persons served as control group and were matched in respect of age, gender and activity level. Training intervention consisted of 5x30 min sessions per week of bicycle exercise with individualised intensity. Compared with baseline, the MS training group demonstrated a significant rightward placement of the aerobic threshold (AT) (VO2+13%; work rate [WR])+11%), an improvement of health perception (vitality+46%; social interaction+36%), an increase of activity level (+17%) and a tendency to less fatigue. No changes were observed for the MS-NI group and the control groups. Maximal aerobic capacity and lung function were not changed by either training or nontraining in all four groups. Overall compliance to the training program was quite low (65%), whereas incidence of symptom exacerbation by physical activity has been lower than expected (6%). Self-directed and supervised exercise were compared with usual care in a clinical trial designed to evaluate the effect of structured exercise on physical functioning and other dimensions of health-related quality of life in women with stages I and II breast cancer.
                One hundred twenty-three women with stages I and II breast cancer completed baseline evaluations of generic and disease- and site-specific health-related quality of life, aerobic capacity, and body weight. Participants were randomly allocated to one of three intervention groups: usual care (control group), self-directed exercise, or supervised exercise. Quality of life, aerobic capacity, and body weight measures were repeated at 26 weeks. The primary outcome was the change in the Short Form-36 physical functioning scale between baseline and 26 weeks.
                Physical functioning in the control group decreased by 4.1 points, whereas it increased by 5.7 points and 2.2 points in the self-directed and supervised exercise groups, respectively (P =.04). Post hoc analysis showed a moderately large (and clinically important) difference between the self-directed and control groups (9.8 points; P =.01) and a more modest difference between the supervised and control groups (6.3 points; P =.09). No significant differences between groups were observed for changes in quality of life scores. In a secondary analysis of participants stratified by type of adjuvant therapy, supervised exercise improved aerobic capacity (+3.5 mL/kg/min; P =.01) and reduced body weight (-4.8 kg; P <.05) compared with usual care only in participants not receiving chemotherapy.
                Physical exercise can blunt some of the negative side effects of breast cancer treatment, including reduced physical functioning. Self-directed exercise is an effective way to improve physical functioning compared with usual care. In participants not receiving chemotherapy, supervised exercise may increase aerobic capacity and reduce body weight compared with usual care. The purpose of this study was to evaluate the effects of a 9-week supervised multicomponent exercise program on functional fitness and body composition in independent older adults. Forty-two adults age 60-86 years were randomly assigned to an exercise or a control group and were evaluated before and after training. The training program consisted of 3 sessions of walking, strengthening, and flexibility exercises per week. The multicomponent training program resulted in significant (p < .005) improvements on the chair stand, arm curl, 6-min walk, and up-and-go tests. The findings of this study indicate that a 9-week training program increased upper and lower body strength, aerobic endurance, and agility/dynamic balance in older adults. The most affected components of functional fitness were lower body strength and aerobic endurance. There was no effect of the 9-week training on body composition. To evaluate the effect of aerobic and variable resistance exercise training on fractionated reaction time (RT) and speed of movement (SM) in elderly individuals, premotor time (PMT), motor time (MT), total RT, and SM were measured in 49 healthy, untrained men and women, 70 to 79 years of age, before and after 6 months of training. Subjects were randomized into either a walk/jog (n = 17), a strength training (n = 20), or a control group (n = 12). Improvements in aerobic capacity were only weakly related to reduced total RT (r = 0.30, p less than .05). Analysis of covariance revealed that there were no differences (p greater than .05) among the three groups after training with respect to PMT, MT, total RT, and SM. These findings indicate that 6 months of aerobic and strength training did not induce significant changes in RT or SM in this group. The purpose of this pilot was to determine whether a strength and flexibility program in frail long-term care facility (LTC) residents would result in improved function.
                A prospective, randomized, controlled, semicrossover trial was designed with participants assigned either to group exercise (EX) or recreational therapy (C). In the EX group, the intervention continued for 1 year. In the C group, recreation continued for 6 months; these controls were then crossed over to the same exercise intervention as the EX group and followed for an additional 6 months. Functional outcomes were measured at baseline and 3, 6, 9, and 12 months for both groups.
                A LTC facility, which included both assisted living (AL) and nursing home (NH) residents.
                Twenty frail residents (5 from NH, 15 from AL) aged 75 to 99 years at one LTC facility.
                After random group assignment, the EX group met 1 hour three times per week. An exercise physiologist and LTC staff conducted sessions which included seated range of motion (ROM) exercises and strength training using simple equipment such as elastic resistance bands (therabands) and soft weights. The C group met three times per week and participated in activities such as painting during the first 6 months, before crossing over to exercise.
                Objective measures of physical and cognitive function were obtained at baseline and 3, 6, 9, and 12 months using the timed get-up-and-go test (TUG), Berg balance scale, physical performance test (PPT), and mini-mental status exam (MMSE). Because we were interested in the impact of exercise on multiple endpoints and to protect the type I error rate, a global hypothesis test was used.
                There was a significant overall impact across the four measures of the exercise intervention (P = 0.013). Exercise benefit as indicated by the difference between exercise and control conditions showed exercise decreased TUG by 18 seconds, which represents an effect size (in standard deviation units) of 0.50, increased PPT scores by 1.3, with effect size = 0.40, increased Berg scores by 4.8, with effect size of 0.32, and increased MMSE by 3.1, with effect size = 0.54. Except for the Berg, 90% confidence intervals on these exercise effects excluded 0.
                Frail elderly in a LTC facility were able to participate and benefit from a strength training program. The program was delivered with low-cost equipment by an exercise physiologist and LTC staff. The advantage of such a program is that it provides recreational and therapeutic benefits. To evaluate the effects of 6 months of pool exercise combined with a 6 session education program for patients with fibromyalgia syndrome (FM).
                The study population comprised 58 patients, randomized to a treatment or a control group. Patients were instructed to match the pool exercises to their threshold of pain and fatigue. The education focused on strategies for coping with symptoms and encouragement of physical activity. The primary outcome measurements were the total score of the Fibromyalgia Impact Questionnaire (FIQ) and the 6 min walk test, recorded at study start and after 6 mo. Several other tests and instruments assessing functional limitations, severity of symptoms, disabilities, and quality of life were also applied.
                Significant differences between the treatment group and the control group were found for the FIQ total score (p = 0.017) and the 6 min walk test (p < 0.0001). Significant differences were also found for physical function, grip strength, pain severity, social functioning, psychological distress, and quality of life.
                The results suggest that a 6 month program of exercises in a temperate pool combined with education will improve the consequences of FM.
There is 'gold' level evidence (www.cochranemsk.org) that supervised aerobic exercise training has beneficial effects on physical capacity and FM symptoms. Strength training may also have benefits on some FM symptoms. Further studies on muscle strengthening and flexibility are needed. Research on the long-term benefit of exercise for FM is needed.
