Objectiveto determine the effects of power training with high movement velocity compared with conventional resistance training with low movement velocity for older community-dwelling people.Designsystematic review of randomised controlled trials.Data Sourcesthe Cochrane Central Register of Controlled TRIALS, PubMed (Medline), EMBASE, CINAHL, PEDro and Scholar-Google.Trialsall randomised or quasi-randomised trials investigating power training with high movement velocity versus conventional resistance training with low movement velocity in elderly persons over the age of 60 years. The primary outcomes were measures of functional outcomes; secondary outcomes were balance, gait, strength, power, muscle volume and adverse effects.Resultseleven trials were identified involving 377 subjects. The pooled effect size for the follow-up values of the functional outcomes was 0.32 in favour of the power training (95% CI 0.06 to 0.57) and 0.38 (95% CI -0.51 to 1.28) for the change value. The pooled effect from three studies for self-reported function was 0.16 in favour of power training (95% CI -0.17 to 0.49).Conclusionpower training is feasible for elderly persons and has a small advantage over strength training for functional outcomes. No firm conclusion can be made for safety.
