Interventions

  • Experimental: External Focus — BEHAVIORAL
    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.
  • Other: Internal Focus — BEHAVIORAL
    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.

Study Details

The overall objective for this clinical trial is to provide evidence for internal and external cueing for physical therapists and other rehabilitation clinicians to optimize resistance training within rehabilitation for older adults. The main questions it aims to answer are: * What is the impact of external focus (providing velocity of movement for each repetition) compared to internal focus (i.e., no cues, control group) on physical percent velocity loss and neuromuscular activation in older adults with sarcopenia? * Does internal and external focus influence motivation and perceptual workload following resistance training in older adults with sarcopenia? Researchers will compare external focus to internal focus to see if external focus impacts percent velocity loss, motivation, and perceived workload. Participants will: * Visit the lab once per week for 3 weeks * Perform exercise testing using a leg press * Answer questionnaires regarding perceived workload and motivation before and after exercise
