Abstract
The purpose of this study was to apply surface EMG decomposition to identify changes in neuromuscular control of lower limb muscles during fatiguing exercise. Trained participants (n=15) completed a repeat sprints cycling fatigue protocol. Motor unit firing rates and motor unit recruitment timings were identified for six muscles. A moderate to strong correlation between firing rates and recruitment timings were identified for individual participant data (r = -0.46 to r = -1.00). No significant group effects were reported when each muscle was examined independently (repeat measures ANOVA; slope, intercept; F < 1.84, p > 0.119). However, changes in regression parameters were indentified for individual participant data. Surface EMG decomposition provides a novel approach for identifying individual changes in neuromuscular control of lower limb muscles during fatiguing exercise.
