Several studies utilizing adult subjects have indicated that static stretching may reduce subsequent strength and power production, possibly for as long as an hour following the stretch. This observation has not been evaluated in children, nor in athletes accustomed to performing static stretches during strength/ power type training sessions. The purpose of this investigation was to determine i...

[Purpose] The aim of this study was to examine whether plantar flexor static stretching and dynamic stretching using an Aero-Step results in changes in foot pressure during gait in healthy adults. [Subjects] Eighteen normal adults were randomly allocated to either a dynamic stretching using an Aero-Step group (DSUAS) group (n = 8) or a static stretching (SS) group (n = 10). [Methods] The DSUAS ...

PURPOSE The present study addressed the lack of data on the effect of different types of stretching on diurnal variations in vertical jump height - i.e., squat-jump (SJ) and countermovement-jump (CMJ). We hypothesized that dynamic stretching could affect the diurnal variations of jump height by producing a greater increase in short-term maximal performance in the morning than the evening throug...

Int J Exerc Sci 3(4) : 214-224, 2010. This study examined the effects of single set dynamic and static stretching on vertical jump height and hip and knee range of motion in a sample of college age recreational males. Forty-two healthy, physically active males (aged 18-24) voluntarily participated in this investigation and were randomly assigned to one of three groups (1 set of 20 seconds dynam...

Over the past 30 years, sport medicine professionals have promoted stretching as a way to decrease the risk of injury. Two potential mechanisms are often proposed by which stretching could decrease injury: a direct decrease in muscle stiffness via changes in passive visco-elastic properties, or an indirect decrease in muscle stiffness via reflex muscle inhibition and consequent changes in visco...

BACKGROUND Warm-up and stretching are suggested to increase hamstring flexibility and reduce the risk of injury. This study examined the short-term effects of warm-up, static stretching and dynamic stretching on hamstring flexibility in individuals with previous hamstring injury and uninjured controls. METHODS A randomised crossover study design, over 2 separate days. Hamstring flexibility wa...

background: there have been numerous researches on elastomeric ligatures, but clinical conditions in different stages of treatment are not exactly similar to laboratory conditions. the aim of this in vitro study was to simulate clinical conditions and evaluate the effect of three stretching patterns on the amount of force, tensile strength (ts) and extension to ts of the elastomers during 8 wee...
