Electromyography is a neuromuscular assessment technique that involved investigating, monitoring, and evaluating bio-potential produced inside in the muscular tissue during voluntary and non-voluntary action. Electromyographical parameter such as maximum surface electromyographical parameter, Root means square amplitude by science supports training programme. In this regards the aim of the study was to evaluate the short-term acute effects of the kinetic chain exercise protocol on Surface Electromyographical Signal Amplitudes in dominant and non-dominant forearm muscles across different recovery intervals (30 seconds, 2 minutes, and 5 minutes). Twenty- seven untrained young adult males were requited for the study. Performed five forearm-focused KCEs. sEMG data were recorded pre-exercise and at 30 seconds, 2 minutes, and 5 minutes of post-exercise. Maximum and RMS amplitudes were analyzed using one-way ANOVA with Bonferroni method. Maximum EMG amplitude significantly decreased in the dominant forearm at 30 seconds (p = 0.004). RMS amplitudes decreased significantly in the non- dominant forearm at 30 seconds (p = 0.01) and 2 minutes (p = 0.04). Values returned near baseline by 5 minutes.
KCE induced a transient suppression of neuromuscular activity, particularly within the first 2 minutes’ post-exercise, with limb-specific variations. The dominant forearm exhibited greater immediate EMG suppression, while the non-dominant forearm showed stronger RMS amplitude reductions. These findings highlight the importance of timing and limb dominance in post-exercise neuromuscular assessments and suggest potential considerations for rehabilitation and performance monitoring.
