Summary

Wearable electromyography reproduced activation onset and overall stroke-waveform shape one week later.

Fifteen competitive rowers completed two all-out 2,000-meter trials seven days apart while a wireless system recorded seven muscles. Activation onset was highly repeatable across every muscle, and each athlete's ensemble stroke waveform remained strongly similar between sessions. Offset, peak position and active duration were less uniformly reliable, while amplitude and active duration showed a reproducible U-shaped pattern through the trial. The small cohort supports personalized monitoring feasibility, not population-wide training prescriptions.
