TrackFrailty Project

Participants in the control group will undergo sham training twice weekly for 30 weeks, consisting of stretching exercises supervised by two exercise physiologists.

In the first 10-week cycle, the less-volume group will perform around 1500 repetitions per intervention. Participants will perform 1-3 sets of 4-7 repetitions per exercise with intensities ranging from 5% to 10% of body weight and 1-10 kg. Strength exercises will include chair squats, seated medicine ball throws, seated knee extensions, seated shoulder presses, standing calf raises, standing biceps curls, seated lateral raises, and chair stand + 4-meter walk. In the second and third 10-week training cycles, volume will increase by 20% with respect to the previous cycles. Two exercise physiologists will supervise training sessions.

In the first 10-week cycle, the more-volume group will perform around 2000 repetitions per intervention. Participants will perform 1-3 sets of 6-10 repetitions per exercise with intensities ranging from 5% to 10% of body weight and 1-10 kg. Strength exercises will include chair squats, seated medicine ball throws, seated knee extensions, seated shoulder presses, standing calf raises, standing biceps curls, seated lateral raises, and chair stand + 4-meter walk. In the second and third 10-week training cycles, volume will increase by 20% with respect to the previous cycles. Two exercise physiologists will supervise training sessions.
