Resistance exercise training : The effects of resisted exercise on ageing muscles are the same as for young muscles: improved muscle strength
increased muscle power - power is a product of both strength and speed. Optimal power reflects how quickly you can exert force to produce the desired movement
improved muscle composition
Evidence: Population studies
Resistance or weight training has been demonstrated to produce increases in muscle strength and power, and also mobility function, in older people living in the following settings: independently in the community
in nursing homes
hospitalised elderly people
A Systematic Review of Randomized Controlled Trials suggested that a low dose of creatine monohydrate along with resisted exercises may improve upper and lower extremities strength in healthy older adults . A randomized control trial in 72 prefrail adults (65 yrs and above) with mild-to-moderate fall risk found significant improvement in fall risk, proprioception, muscle strength, reaction time, postural sway and health-related quality of life with the Multi-system Physical Exercise (MPE) which consisted of proprioceptive, muscle strengthening, reaction time, and balance training exercises . Gender differences
Increased muscle quality from resistance training is a common finding in older adults, and in men there appears to be no difference in young versus old, but there is a study that suggests that older women have a blunted response relative to younger women. Frequency of resistance training
Studies have demonstrated that resistance training regimes performed once, twice or even three times a week all result in strength improvements. Length of training programme
There are many studies which clearly demonstrate that older people who participate in resistance train
