Neuromuscular fatigue after maximal stretch-shortening cycle exercise.
To examine some possible sites of fatigue during short-lasting maximally intensive stretch-shortening cycle exercise, drop jumps on an inclined sledge apparatus were analyzed. Twelve healthy volunteers performed jumps until they were unable to maintain jumping height > 90% of their maximum. After the workout, the increases in the blood lactate concentration and serum creatine kinase activation ...
متن کاملStretch-shortening Cycle in the Upper Extremities
Miyaguchi, K and Demura, S. Gender difference in ability using the stretch-shortening cycle in the upper extremities. J Strength Cond Res 23(1): 231–236, 2009—A gender difference in ability using the stretch-shortening cycle (SSC ability) in the upper extremities has not been studied in detail. This study aimed to devise an index to evaluate SSC ability during powerful elbow flexion and to exam...
متن کاملPopped Sarcomeres Regain Filament Overlap in a Stretch-shortening Cycle
INTRODUCTION The effects of stretch-induced damage, such as loss of force and appearance of localized sarcomere damage, are often explained by the popping sarcomere hypothesis [1]. This hypothesis contends that sarcomeres operating on the descending limb of the force-length relationship (FLR) are unstable. During a stretch, they are thought to undergo rapid lengthening until filament overlap is...

متن کاملEffects of different dropping intensities on fascicle and tendinous tissue behavior during stretch-shortening cycle exercise.
This study examined whether the elasticity of the tendinous tissues plays an important role in human locomotion by improving the power output and efficiency of skeletal muscle. Ten subjects performed one-leg drop jumps (DJ) from different dropping heights with a constant rebound height. The fascicle length of the vastus lateralis muscle was measured by using real-time ultrasonography during DJ....
