[email protected] ABSTRACT Introduction: Stretching is a therapeutic technique and may be used as a form of warm-up to increase flexibility or decrease pain throughout the movement, with objective to improve performance and reduce the risk of injury. Objective: ...

The purpose of t his study was to investigate the acute effects of pre-exercise static and dynamic stretching on peak torque of the knee extensors in female athletes and non-athletes. Thirty subjects (15 athletes and 15 nonathletes) completed three tests on an isokinetic dynamometer. After performing a randomly assigned preexercise stretching protocol (no stret ching, static or dynamic) the sub...

The purpose of this study was to compare the acute effects of static stretching; dynamic exercises and high volume upper extremity plyometric activity on tennis serve performance. Twenty-six elite young tennis players (15.1 ± 4.2 years, 167.9 ± 5.8 cm and 61.6 ± 8.1 kg) performed 4 different warm-up (WU) routines in a random order on non-consecutive days. The WU methods consisted of traditional...

The purpose of present study was to examine the effects of short time static and dynamic stretching of muscles on kinematics variability of lower extremity in healthy active males during cycling. 15 physical education and sport sciences male students from Kharazmi University voluntarily participated in this study. Subjects referred to the laboratory during two days, with 48 hours intervals betw...

Background & purpose: Most sports individuals or athletes including tennis players perform stretching during warm-up prior to physical activity in order to prevent injuries and enhance sports performance by improving flexibility. Traditionally static stretching exercises have been a prominent feature of warm up routines. On the other hand, dynamic stretching improves knee joint position sense, ...

The purpose of this study was to compare the effects of static and dynamic stretching on quadriceps muscle activation during maximal soccer instep kicking. The kicking motion of twelve male college soccer players (body height: 174.66 ± 5.01 cm; body mass: 72.83 ± 4.83 kg; age: 18.83 ± 0.75 years) was captured using six synchronized high-speed infra-red cameras whilst electromyography (EMG) sign...

A comparison of assisted and unassisted proprioceptive neuromuscular facilitation techniques and static stretching. J Strength Cond Res 26(5): 1238-1244, 2012-Proprioceptive neuromuscular facilitation (PNF) stretching often requires a partner. Straps are available allowing an individual to perform PNF stretching alone. It is not known if a strap provides similar improvements in the range of mot...

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...

This paper deals with the effect of the intrinsic material length-scale parameter on the stability and natural frequency of a rectangular micro-plate for two different cases; fully clamped and fully simply supported. A variational formulation based on Hamilton’s principle and the modified couple stress theory is used to obtain the nonlinear governing equation of a micro-plate incorporating the ...
