El ejercicio físico y su efectividad sobre la condición física en personas mayores frágiles. Revisión sistemática de ensayos clínicos aleatorizados

Performing exercise to maintain a good physical condition is crucial to improve and prevent frailty in older adults. The aim of this review was to assess the beneficial effects of physical exercise on fitness in frail older adults. A thorough literature search of randomised clinical trials (RCT) in the last 15 years was performed on different electronic databases. The methodological assessment of studies was obtained using the PEDro scale. Ten RCT were included, providing a final sample of 1,130 individuals. Scores on the PEDro scale ranged from 5 to 8/10. Multicomponent training programs seem to be the best strategy to improve fitness outcomes. Further studies should be performed in order to optimise the design of supervised exercise programs, and further research is needed in hospital and institutionalised settings.
