Healthy, physically active adults (18-40 y; Tegner ≥5) will perform three repetitions per exercise with metronome-paced phases (≈3 s concentric, 3 s isometric, 3 s eccentric), 5-s rest between repetitions and 2-min between exercises; load will be individualized to reach OMNI RPE 6-8. Surface EMG (TeleMyo DTS; Noraxon) will be recorded from the latissimus dorsi (medial and lateral) and selected synergists (teres major, infraspinatus, posterior deltoid, triceps); electrode placement will follow SENIAM recommendations. Signals will be band-pass filtered (20-500 Hz), rectified, RMS-smoothed with a 100-ms window, and normalized to %MVIC using standardized MVC tests; exercise\u002FMVC order will be randomized to limit bias. The primary outcome is mean normalized EMG amplitude per exercise; secondary outcomes include peak amplitude and categorical activation levels (low ≤20% MVIC, moderate 21-40%, high 41-60%, very high \\>60%). The study involves minimal risk (possible mild skin irritation under electrodes and transient post-exercise fatigue).",[69],"Muscle Activation",[71,72,73],"Latissimus Dorsi","Shoulder","Electromyography","2025-12-22",{"date":76,"type":77},"2025-12-29","ACTUAL",{"date":79,"type":77},"2025-10-12",{"date":81,"type":65},"2026-02-25",{"name":5,"class":6},1]
