The prevalence of sports injuries in martial arts is high. Most Taekwondo injuries also occur in the lower extremities. The aim of this study is to compare the effect of a period of plyometric exercises, with and without stretching exercises, on knee valgus dynamics, flexibility and functional variables of elite female taekwondo athletes at risk of anterior cruciate ligament injuries.  45 elite...

Introduction The gastrocsoleus complex via the Achilles tendon exerts a plantar flexion moment on the foot and ankle. The manifestation of this moment on the forefoot during gait is that of plantar pressure. Stretching is routinely recommended by physicians to provide relief of forefoot pain, heel pain and plantar fasciitis, as well as being advised prior to sporting activities to minimize inju...

[Purpose] The present study assessed the effects of using an unstable inclined board on the active and passive ankle range of motion in patients with ankle stiffness. [Subjects] The study included 10 young female patients with ankle stiffness. [Methods] The patients were divided into the following two groups: a group that performed ankle dorsiflexion stretching exercises using a wooden inclined...

The essential exercises for a home rehabilitation program for tennis or golfer's elbow include stretching and strengthening (figure 1) to improve flexibility and range of motion, and to reduce forces on the affected tendon. Slow, passive stretching exercises and gentle strengthening exercises can be started right away.

[Purpose] To examine how stretching, plyometric, and treadmill exercises influence the dynamic balance necessary for sports activities. [Subjects and Methods] Twenty-two healthy subjects participated in this study. The subjects conducted stretching, plyometric exercises, and treadmill walking for set times over a period of three days. The subjects' dynamic balance was then measured. The measure...

Vibrational sum-frequency generation (SFG) spectroscopy of interfacial water at mineral/aqueous interfaces is extended to the near-IR range containing the low cross section stretch + bend combination bands (νcomb = νOH + δHOH) of liquid water at silica surfaces near 5000-5300 cm(-1), for the first time. The assignments of SFG spectra are supported by FTIR and Raman spectroscopic measurements of...

[Purpose] The purpose of this study was to determine the effects of deep-breathing and proprioceptive neuromuscular facilitation stretching exercises on upper limb lymphedema in stroke patients. [Subjects and Methods] The study consisted of 10 patients with lymphedema that had occurred after stroke. Neurodevelopmental treatment was applied in the same manner as that used for the existing treatm...

[Purpose] This study compared and analyzed use of an existing ankle ramp and a newly developed ankle ramp for stretching exercises. [Subjects] Fourteen subjects were included; they were stroke patients more than 6 months after onset, with no orthopedic or biological problems in the legs, so independent gait was possible. [Methods] The subjects performed stretching exercises for 5 min with an ex...

BACKGROUND Effective treatments for chronic lateral epicondylosis have not been studied adequately. Eccentric overload exercises have been used with success for other chronic tendinopathy, mainly Achilles and patellar. HYPOTHESIS/PURPOSE To compare a wrist extensor eccentric strengthening exercise program with a wrist extensor stretching/modality program for the treatment of chronic lateral e...
