Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Participants will perform repetitive squatting until volitional exhaustion while their muscular activity is recorded. They will do so on two different test sessions with an interval of one week in between.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Fatigue
To induce muscular fatigue, participants will perform a repetitive bodyweight squat until 1) the squat cannot be performed over the full range of motion for 2 consecutive repetitions and 2) physical exertion occurs (10-point Borg scale).
Surface Electromyography
The primary lower limb muscles to be monitored include the gluteus medius, rectus femoris, vastus lateralis (quadriceps ), biceps femoris (hamstrings), tibialis anterior, and gastrocnemius medialis (calves). This setup fully utilizes a 16-channel sEMG system by monitoring each muscle group bilaterally to capture comprehensive data on muscle activity and fatigue.
