Effect of Task Failure on Intermuscular Coherence Measures in Synergistic Muscles

Figure 2

Changes in the muscle module at task failure. The synergistic activation of the RF, VL, and VM in the knee extension task is exploited using the muscle synergy framework. Muscle weighting coefficients are reported for each muscle and each condition (baseline versus task failure) for both (a) LIE and (b) HIE. (c) The compound synergy activation is reported for both LIE and HIE at baseline and task failure. Significance is reported for the comparison baseline versus task failure. , . RF: rectus femoris; VL: vastus lateralis; VM: vastus medialis; LIE: low-intensity exercise; HIE: high-intensity exercise. All bar plots are presented as the mean ± standard deviation.
