Endpoints
muscle fatigue
The endpoints of this study were maximal strength and muscle power, which were measured using the bilateral leg press exercise (Exercycle S.L., BH Group, Vitoria, Spain). The 1RM test involved progressively increasing the load until the participant could no longer lift any additional weight while maintaining proper technique and full range of motion. The 1RM value was determined as the maximum load that the participant could move through a complete range of motion. The participants' 1RM was determined through four to five attempts with a 3‐min recovery period between attempts. During testing, participants were verbally encouraged to always produce their maximum strength.After obtaining the 1RM values in the leg press, the participants performed the same exercise with two different loads to assess peak power and mean propulsive power: ≤30% of 1RM and between 45 and 55% of 1RM. We assessed the loads ≤30% of 1RM because these loads are more associated with low strength demand functional tasks such as gait ability, and the loads between 45% and 55% of 1RM because they are more associated with high strength demand functional tasks, such as rising from a chair.The ability to maintain muscle power output during a set of 10 repetitions of leg press at maximal volitional intensity at loads ranging between 45% and 55% of 1RM was also used as an endpoint to measure changes in muscle fatigue.
