Trial Summary

What is the purpose of this trial?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

Eligibility Criteria

This trial is for older adults with sarcopenia, which is a condition involving muscle loss. Participants should be able to visit the lab weekly for three weeks and perform leg press exercises. Specific inclusion or exclusion criteria are not provided.

Inclusion Criteria

I can take care of myself without help.

Exclusion Criteria

I have Parkinson's, Multiple Sclerosis, or issues with circulation or swelling.

Participant Groups

The study tests whether giving feedback on movement velocity (external focus) during resistance training affects muscle activation and self-perception differently than no cues (internal focus). It measures physical performance, motivation, and workload perception in participants.
