QUESTION Does the localised application of vibration over the hamstrings improve hamstring extensibility? DESIGN Randomised controlled trial with concealed allocation, intention-to-treat analysis, and assessor blinding. PARTICIPANTS 30 non-athletic females (aged 18-22 yrs) with limited hamstring extensibility bilaterally. INTERVENTION The experimental group received 3 sessions of localise...

Injuries to the hamstring muscles are common in athletes. Track and field, Australian football, American football and soccer are examples of sports where hamstring injuries are the most common. The purpose of this study was to investigate whether there is a correlation between a hamstring injury prognosis and its characteristics of imaging parameters. The literature search was performed in the ...

High hamstring tendinopathy is an uncommon overuse injury seen in running athletes. Patients typically report deep buttock or thigh pain. A detailed physical examination and, occasionally, imaging studies are necessary to confirm the diagnosis. Rehabilitation involves soft-tissue mobilization, frequent stretching, and progressive eccentric hamstring strengthening and core stabilization exercise...

BACKGROUND Minimising the likelihood of injury to the anterior cruciate ligament (ACL) during abrupt deceleration requires proper synchrony of the quadriceps and hamstring muscles. However, it is not known whether simple verbal instructions can alter landing muscle activity to protect the knee. OBJECTIVE To assess the efficacy of verbal instructions to alter landing muscle activity. METHODS...

This study aimed to examine the effects of kinesiology taping (KT) and different TRX suspension workouts on the amplitude of electromyographic (EMG) activity in the core muscles among people with chronic low back pain (LBP). Each participant (total n = 21) was exposed to two KT conditions: no taping and taping, while performing four TRX suspension exercises: (1) hamstring curl, (2) hip abductio...

PURPOSE The potential mechanisms of hamstring strain injuries in athletes are not well understood. The study, therefore, was aimed at understanding hamstring mechanics by studying loading conditions during maximum-effort overground sprinting. METHODS Three-dimensional kinematics and ground reaction force data were collected from eight elite male sprinters sprinting at their maximum effort. Ma...

Background: Hamstring injuries are common in sports that involve rapid, forceful lengthening of the hamstring muscles, such as sprinting, jumping, and kicking. This type injury is more likely to occur team football handball. Objectives: The purpose this study was investigate chronic effects proprioceptive neuromuscular facilitation (PNF) stretching on muscle strength activity muscle. Methods: S...

Children with spastic cerebral palsy (CP) often develop hamstring contractures; however, the mechanism of contracture formation is not known. Contractures represent a resistance of muscle to increased length, but the structural elements responsible for increased stiffness are not known [1]. Previous work showed that single fibers from “contractured” muscle tissue has increased passive stiffness...

BACKGROUND Semitendinosus and gracilis muscles whose tendons are used in surgical reconstruction of the anterior cruciate ligament maintain their contractile ability, and a limited decrease of hamstring muscles force is observed postoperatively despite important changes. The goal was to quantify the influence of the myofascial structures on excursions and moment arms of knee muscles to attempt ...
