简要总结
The aims of this study were to:
- Compare the effects of low-dose Maximal Intent and Controlled Tempo Resistance Training on untrained healthy older adults' quality-of-life, functional capacity, and strength.
- Qualitatively explore perceptions of Maximal Intent and Controlled Tempo Resistance Training in older adults.
Older adults are defined as being 60 or more years of age.

研究组 & 干预措施
Maximal-intent Resistance Training - 3x5 (MI3x5)
The max-intent group were instructed and encouraged to deliberately commit to exerting maximal effort and force during the concentric phase of the leg press with the intention of achieving the greatest velocity possible. This group completed 3 sets of 5 repetitions at 60% one-repetition maximum.
干预措施: Leg Press Resistance Training (3x5) (Other)
Maximal-intent Resistance Training - 5x5 (MI5x5)
The max-intent group were instructed and encouraged to deliberately commit to exerting maximal effort and force during the concentric phase of the leg press with the intention of achieving the greatest velocity possible. This group completed 5 sets of 5 repetitions at 60% one-repetition maximum.
干预措施: Leg Press Resistance Training (5x5) (Other)
Controlled-tempo Resistance Training - 3x5 (CT3x5)
The controlled-tempo group followed a metronome for both eccentric and concentric phases of the leg press with the intention of maintaining a steady three-second concentric and three-second eccentric. This group completed 3 sets of 5 repetitions at 60% one-repetition maximum.
