Muscle Coactivation during Stability Exercises in Rhythmic Gymnastics: A Two-Case Study

<div>Typical course of a–p GRF (a), m–l GRF (b), and EMG signal (c) support leg during flat foot standing in back split without hand support. Positive values represent components of the posterior and lateral GRF; negative values are components of the anterior and medial GRF.</div>
