简要总结
This study will investigate the impact of two unique progression models for power training in a sample of healthy older adults. The objective is to identify the most practical methodology for implementing power training, which is considered a critical marker of functional capacity in older populations.

研究组 & 干预措施
RPE-Based Power Training
The RPE system will be based on movement speed with an unloaded condition producing maximal speed (RPE=10) and a 1RM producing minimal speed (RPE = 1). If RPE is above 5, loads will be increased by 5% for upper body exercises and 2.5% for lower body exercises. If the RPE = between 4 and 5 the load will remain unchanged. If RPE falls below 4, loads will be lowered using the same percentages.
干预措施: RPE-Based Power Training (Behavioral)
Power Plateau-Based Power Training
Following two training sessions, the average power for each exercise will be calculated. When average power increases by a minimum of 5% from session one to session two, the load will remain unchanged to continue to reap power improvements. When the average power does not increase by at least 5% from session one to two, the load will be increased by the same protocol described above. Loads will only decrease when subjects cannot complete all repetitions with adequate form.
干预措施: Power Plateau-Based Power Training (Behavioral)
结局指标
主要结局
Change in neuromuscular performance as measured by 1-repetition maximum (1RM)
时间窗: Baseline, 12 weeks
Maximal load that can be lifted in one repetition (1RM) will be assessed in both leg press and chest press exercises. The loads on the testing equipment will be increased across 5 to 7 testing repetitions. The persons 1RM will be the highest load the person can move through the range of motion of the exercise. There are no minimum or maximum scores for this test. The higher the 1RM the stronger the person is. The unit of measurement is kilograms.
Change in neuromuscular performance as measured by Watts
时间窗: Baseline, 12 weeks
This test measures the power a person can produce at maximal speed using loads of 20%, 40%, 60%, 80%, and 90% of 1RM for the chest press and leg press. Power shows how fast a person can do work. Unit of measure is Watts.
次要结局
- Change in the Speed of the Ten-Meter Walk Test.(Baseline, 12 weeks)
- Change in Time for the Five Times Sit-to-Stand Test.(Baseline, 12 weeks)
- Change in Distance of the Seated Medicine Ball Throw.(Baseline, 12 weeks)
- Change in the time required to complete the timed Up-and-Go Test.(Baseline, 12 weeks)
