Correlation between Vastus Lateralis and Vastus Medialis MUAPamp before (PRE) fatigue and ΔSampEn. Data are presented as individual values. Grey band represents the 95% confidence intervals. “rs” represents the Spearman correlation coefficient and “R2” represents the amount of variation of the dependent variable that can be explained by the independent variable.
