PRT versus control and versus power exercise
1.PRT
Type of Ex: 4UL/4LL & squats
Equipment: Keiser Inc.
Intensity: 50% ‐> 70% of 1RM by week 8, 80% of 1RM the last 8 weeks
Frequency: Ex3
Reps/Sets: 6‐8/3
Duration: 16 weeks
Setting: not reported (Gym?)
Supervision: not reported
Adherence: not reported
2. Control Group: maintain usual activity and attend 3 educational presentations over the study period
3. Power Ex Group: N=11, mean age = 72.3 years (SD = 6.7), the same exercise as the PRT group but did jump squats instead of squats, 6‐8 repetition at 40% of 1RM, move as fast as possible |
