The Influence of Movement Velocity Biofeedback on Muscle Activation and Self Perception in Older Adults With Sarcopenia

Participants will perform a short, standardized warm-up (1 set of 10 repetitions of 20% of the participant's estimated 1-repetition maximum). Following the warm-up, participants will perform 30 repetitions using 50% of their estimated 1-repetition maximum on a leg press machine. Participants will receive visual feedback from a linear position transducer for each repetition, indicating the speed of the last repetition/movement.

Arm Description: Participants will perform a short, standardized warm-up (1 set of 10 repetitions of 20% of the participant's estimated 1RM). Following the warm-up, participants will perform 30 repetitions using 50% of their estimated 1-repetition maximum on a leg press machine. Participants will NOT receive visual feedback for each repetition. This is the control condition.
