Factores determinantes del rendimiento cuando el Counter Movement Jump se realiza en fatiga aguda

This work analysed the changes that occur in kinetic-temporal parameters and the electromyographic activity of lower limb muscles during the performance of maximum Counter Movement Jumps (CMJ) done with and without muscular fatigue, to explain the changes in performance in both situations. The vertical strength of fifty jumps performed by ten male sportsmen before and after a fatigue protocol was registered. Records of surface electromyography were obtained for six lower limb muscles; in addition, activation level and intermuscular coordination were analysed. For analysis purposes, negative an...
