About this trial
The objective of the current study is to determine whether lifting lighter loads close to failure improves strength training adaptations and function in older adults. The main questions it aims to answer are:
1. The effect of light loads on physical function 2. The effect of light loads on muscle mass, power, and strength
Researchers will compare a light-load, high-repetition program to a standard strength training program. Participants will perform supervised strength training twice per week for 20 weeks.
