The countermovement jump (CMJ) and isometric hip abduction (IABS), adduction (IADS), and posterior chain (IPCS) strength tests are commonly used to profile neuromuscular performance and fatigue characteristics in elite-level academy football players. 1 – 7 Compulsory inclusion of CMJ testing in

fascial chains may have significant clinical implications in PF. Specific to the posterior chain recent evidence demonstrates the link between remote myofascial structures and PF. These studies demonstrate that poor extensibility of gastrocnemius and hamstrings muscles may be associated with PF. 15 , 16

In fact, in a recent study, the reduction in sprinting capacity of Rugby sevens players following an intense session was largely correlated with the amount of supramaximal running distance during the session. 7
Acute Effects of Gastrocnemius/Soleus Self-Myofascial Release Versus Dynamic Stretching on Closed-Chain Dorsiflexion

effective in creating increased ankle DF ROM, the addition of a dynamic DD stretch to a self-myofascial release session did produce a greater overall absolute change. It appears that the weight-bearing nature of DD increases overall tension throughout the posterior chain of the body, producing additive
