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 Controversy exists on stretching and warm-up in injury prevention. We hypothesized that warm up has a greater effect on Achilles tendon biomechanics than static stretching. This study investigated static stretching and warm-up on Achilles tendon biomechanics in recreational athletes, in vivo. MATERIALS AND METHODS Ten active, healthy subjects, 5 males, 5 females, With a mean age of...

This investigation was conducted to determine the effect of 2 different warm-up treatments over time on driver clubhead speed, distance, accuracy, and consistent ball contact in young male competitive golfers. Two supervised warm-up treatments, an active dynamic warm-up with golf clubs (AD) and a 20-minute total body passive static stretching routine plus an identical AD warm-up (PSS), were app...

Purpose: Main aim of the study is to evaluate effectiveness vision exercise with chin nodding and neck stretching among computer users also intend show effect figure eight only. Methods: This randomized controlled trial was carried out in Islamabad Rawalpindi. Computer syndrome symptoms data will be collected from self-administered questionnaire level instrument questionnaire. 33 participants (...

[Purpose] The purpose of the present study was to examine the effects of ankle joint muscle strengthening and proprioceptive exercises accompanied by functional electrical stimulation on stroke patients' balance ability. [Methods] For six weeks beginning in April 2015, 22 stroke patients receiving physical therapy at K Hospital located in Gyeonggi-do were divided into a functional electrical st...

OBJECTIVES To compare a walking exercise to a stretching exercise during pregnancy in high-risk women who were sedentary and had previously experienced preeclampsia. METHODS A randomized clinical trial of the effects of the two types of physical exercises was conducted between November 2001 and July 2006 in Washtenaw County, Michigan. Both groups engaged in the assigned exercise five times a ...

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...

Purpose: Many patients with Achilles Tendinopathy do not respond to eccentric training. The aim of the present case report is to find out the effect of eccentric concentric training of gastrocnemius and soleus combined with isometric contraction of gastrocnemius and static stretching exercises of gastrocnemius and soleus on pain and disability in a patient experiencing Achilles Tendinopathy. Me...

PURPOSE Previous studies report that static stretching (SS) impairs running economy. Assuming that pacing strategy relies on rate of energy use, this study aimed to determine whether SS would modify pacing strategy and performance in a 3-km running time-trial. METHODS Eleven recreational distance runners performed a) a constant-speed running test without previous SS and a maximal incremental ...

Amiri-Khorasani, M, Abu Osman, NA, and Yusof, A. Acute effect of static and dynamic stretching on hip dynamic range of motion during instep kicking in professional soccer players. J Strength Cond Res 25(6): 1647–1652, 2011—The purpose of this study was to examine the effects of static and dynamic stretching within a pre-exercise warm-up on hip dynamic range of motion (DROM) during instep kickin...
