Muscle damage induced by stretch-shortening cycle exercise
Medicine & Science in Sports & Exercise, 1998Strenuous stretch-shortening cycle exercise was used as a model to study the leakage of proteins from skeletal muscle.The analysis included serum levels of creatine kinase (S-CK), myoglobin (S-Mb), and carbonic anhydrase (S-CA III). Blood samples from power- (N=11) and endurance-trained (N=10) athletes were collected before, 0, and 2 h after the ...

Leg stiffness modulation during exhaustive stretch‐shortening cycle exercise
Scandinavian Journal of Medicine & Science in Sports, 2006The present study examined the effects of muscle activity modulation on leg stiffness during an exhaustive stretch‐shortening cycle (SSC) exercise in eight male subjects. Reaction force, electromyography (EMG) of the soleus (Sol), gastrocnemius (Ga) and vastus lateralis (VL) muscles and sledge seat position were recorded during the SSC exercise ...

Effects of Stretching on Performances Involving Stretch-Shortening Cycles
Sports Medicine, 2013Alongside its role in athletic conditioning, stretching has commonly been integrated in warm-up routines prior to athletic performance. Numerous studies have reported detrimental acute effects on strength following stretching. Consequently, athletes have been recommended to discontinue stretching as part of warm-ups.

Stretch-Shortening Cycle in Roller Ski Skating: Effects of Technique
International Journal of Sports Medicine, 1998The purposes of this study were 1) to examine the occurrence of the stretch-shortening cycle (SSC) in the three principal techniques of ski skating and 2) to test the hypothesis that differences in SSC behaviour may explain the choice of a technique when the grade is altered. Ten highly skilled male cross-country skiers roller skied at 5.3+/-0.1 m x s(-

Reduced stretch-reflex sensitivity after exhausting stretch-shortening cycle exercise
European Journal of Applied Physiology and Occupational Physiology, 1996The stretch-shortening cycle (SSC) is an effective and natural form of muscle function but, when repeated with sufficient intensity or duration, it may lead to muscle damage and functional defects. A reduced tolerance to impact has been reported, which may be partly attributed to a reduced stretch-reflex potentiation.

Lower Leg Morphology and Stretch-Shortening Cycle Performance of Dancers
Journal of Applied Biomechanics, 2018Greater levels of bone ultimate fracture load, bone stress–strain index, muscle cross-sectional area, and maximal voluntary isometric plantarflexion (MVIP) strength of the lower leg may be adaptations from chronic exposure to stretch-shortening cycle (SSC) actions.

Motor development and gender effects on stretch-shortening cycle performance
Journal of Science and Medicine in Sport, 2001A substantial part of human movement such as jumping, hopping, leaping and other bounding movements are improved by making a counter-movement. These activities are often described as stretch shortening cycle (SSC) movements. The aim of this study was to determine whether the SSC affects performance in vertical jump in children to the same extent as it ...

Load-dependent movement regulation of lateral stretch shortening cycle jumps
European Journal of Applied Physiology, 2010The classical stretch shortening cycle (SSC) describes sagittal joint flexion-extensions in motions like running or hopping. However, lateral movements are integral components of team sports and are associated with frontal plane joint displacements.

EMG signal amplitude normalization technique in stretch-shortening cycle movements
Journal of Electromyography and Kinesiology, 1993Analysis of functional movements using surface electromyography (EMG) often involves recording both eccentric and concentric muscle activity during a stretch-shorten cycle (SSC). The techniques used for amplitude normalization are varied and are independent of the type of muscle activity involved.

History-dependent properties in a stretch-shortening cycle
2021The present work deals with the stretch-shortening cycle (SSC), a combined muscle action consisting of a stretch (eccentric phase) directly followed by a shortening (concentric phase) contraction. The SSC is a component of many everyday and athletic movements and is associated with higher mechanical efficiency compared to a pure shortening contraction.
