Abstract Summary
The stretch-shortening cycle is a naturally occurring muscle-tendon function that serves to potently enhance performance, and when implemented until exhaustion results in neuromuscular fatigue that differs from that induced solely by isolated contractions. Comparable with previous reports with soleus, we found changes in medial gastrocnemius muscle architecture after exhaustion. Although further investigation is needed, these alterations seem to result from a unique interaction at musculoskeletal and neural levels.
