Summary

The present study is a crossover randomized controlled trial that aims to investigate the effects of concurrent exercise training over usual care on physical performance, muscle strength, and myokines concentrations in frail older adults living in nursing homes.The main questions it aims to answer is: Can a 12-week exercise intervention provide beneficial effects on physical performance, muscle strength and myokines among the most frail participants? Researchers will compare this intervention to usual care. Nursing homes (comprising participants) will be randomly assigned to a sequence of interventions (AB or BA), being A -exercise and B usual care. Participants will be assessed before and after each intervention.

Detailed description

The present study is a crossover randomized controlled trial that aims to investigate the effectiveness of a concurrent exercise training over usual care on physical performance, muscle strength, and myokines concentrations in frail older adults living in nursing homes. Nursing homes will be randomly assigned to receive a sequence of interventions (AB or BA), being A -exercise and B usual care. Participants will receive a 12-weeks of either exercise intervention or usual care. A 4-week washout period will be conducted between interventions. Participants will assessed before and after each intervention.

Type	Name	Description
BEHAVIORAL	Exercise training	The exercise intervention will take place at the nursing homes and consists of 12 weeks of supervised concurrent exercise training, performed thrice weekly on nonconsecutive days to avoid overtraining and fatigue. Each session will last 50-60 min and consist of a warm-up, resistance plus aerobic training, and a 5-min cool-down period. The resistance training will comprise 2-3 sets of 10 to 15 repetitions with a load equivalent to 40 to 70% of the 1-repetition maximum (1RM) for upper (i.e., bicep curl) and lower body exercises (i.e., seated knee extension). The sit-to-stand exercise will be performed as fast as possible according to each participant's capacity without external load. The recovery between sets is between 1 and 2 min. Afterwards, participants will perform walking exercises with changes in pace and direction. The duration of the aerobic training will progress from 5-10 min duration in the first weeks to 10-15 min. The sessions will end with stretching exercises.The exercise
