CONTEXT Exercise-associated muscle cramps (EAMC) are a common condition experienced by recreational and competitive athletes. Despite their commonality and prevalence, their cause remains unknown. Theories for the cause of EAMC are primarily based on anecdotal and observational studies rather than sound experimental evidence. Without a clear cause, treatments and prevention strategies for EAMC ...

BACKGROUND Static stretching (SS) is a recovery intervention used for the reduction of muscle soreness postexercise. The effects of SS on elite young footballers have received little attention, and therefore the aim of this study was to assess the effects of SS on muscle recovery following competitive soccer matches in elite young footballers. METHODS Ten male participants (16±1 years) were r...

Background: For decades, static stretching has been the standard benchmark for training programs, because it has been shown to increase flexibility compared with other methods of stretching. Objective: The current study investigated and compared the effects of active dynamic stretching and passive static stretching on hamstring tightness. Me...

Stretching is a common activity used by athletes, older adults, rehabilitation patients, and anyone participating in a fitness program. While the benefits of stretching are known, controversy remains about the best type of stretching for a particular goal or outcome. The purpose of this clinical commentary is to discuss the current concepts of muscle stretching interventions and summarize the e...

the purpose of the present study was to investigate whether duration of static stretching could affect the maximal voluntary contraction (mvc) and flexibility of hamstring muscles. 10 male physical education students randomly performed three warm-up protocols on different days. the protocols included: a) five minutes of treadmill run and 45 seconds (3×15 seconds) of static stretching of hamstri...

objective: to compare the effects of aerobic and stretching exercises on severity of primary dysmenorrhea. materials and methods: this randomized clinical trial was conducted on 105 female students who were suffering from primary dysmenorrhea. the participants were divided into aerobic exercise, stretching exercise, and control groups. the two intervention groups did the exercises three times a...

We introduce the notion of key stretching, a mechanism to convert short s-bit keys into longer keys, such that the complexity required to brute-force search a s+ t-bit keyspace is the same as the time required to brute-force search a s-bit key stretched by t bits.

OBJECTIVES The purpose of this study was to examine the effects of the use of a vapocoolant blend of pentafluoropropane and tetrafluoroethane (Gebauer's Spray and Stretch) on hip flexion stretching. METHODS Thirty volunteers were randomly assigned to spray and stretch treatment and stretch only control groups. Each group was assessed pre- and posttest on passive and active hip flexion range o...

background hamstring muscles play an important role in functional activities and relaxation and most people around the world suffer from the shortened muscles. different methods of repairing were suggested and there were disagreements with regard to determination of one technique with high efficiency. objectives this study aimed to introduce more effective method, either a static stretch or hol...

In present study, the dynamics of stretching-stretching and stretching-bending entanglement in H2O are studied with considering the inherent decoherence process. It is shown that the excitation in the bending vibration can lead to the decrease of the generation rate of stretching-stretching entanglement for the non-superposed state and the degeneration of entanglement for the initial entangled ...
