BACKGROUND Traditionally, stretching exercises are considered as basic components of warm up aiming to prepare the musculoskeletal system for performance and to prevent injuries. OBJECTIVES The purpose of this study was to examine the effects of different agonist and antagonist stretching arrangements within a pre-exercise warm-up on hip static (SROM) and dynamic range of motion (DROM). MAT...

[Purpose] The aim of present study was to compare the effectiveness of modified hold-relax stretching and static stretching in improving the hamstring muscle flexibility. [Subjects and Methods] Forty-five male subjects with hamstring tightness were included in this study. The subjects were randomly placed into three groups: the modified hold-relax stretching, static stretching and control group...

Fibroblasts in intact tendons align with stretching direction, but they tend to orient randomly in healing tendons. Therefore, a question arises: Do fibroblast responses to mechanical stretching depend on their orientation? To address this question, human patellar tendon fibroblasts were grown in custom-made silicone dishes that possess microgrooved culture surfaces. The direction of the microg...

[Purpose] This study aimed to clarify the immediate effects of a combined transcutaneous electrical nerve stimulation and stretching protocol. [Subjects] Fifteen healthy young males volunteered to participate in this study. The inclusion criterion was a straight leg raising range of motion of less than 70 degrees. [Methods] Subjects performed two protocols: 1) stretching (S group) of the medial...

Infrared spectra of some deuterio analogues of carboxylic acids in heavy water have been investigated and their spectral behavior in carbonyl stretching frequency region have been interpreted in terms of their structural behavior in aqueous solutions. It has been shown that a linear relationship exists between carbonyl stretching frequency of solvated acids at infinite dilution and their...

Stacking over 2300 P-to-S receiver functions recorded by 33 SAFARI (Seismic Arrays for African Rift Initiation) broadband seismic stations that we installed in the vicinity of Malawi and Luangwa rift zones (MRZ LRZ, respectively) reveals significant variations crustal thickness (32.8–46.3 km) Vp/Vs (1.69–1.85). The resulting stretching factor is about 1.05–1.08 MRZ, which approximately 10–40% l...

introduction: contrast sensitivity is one of the most important psychophysical tests that may be used for the evaluation of refractive state of eye and retinal image quality. yellow vs. blue color contrast sensitivity may be more suitable in this regard. materials and methods: thirty myopic eyes were considered in this study. yellow vs. blue color contrast sensitivity was evaluated under the sa...

OBJECTIVE: To compare the effects of low-load, short-duration stretching with or without high-intensity, pulsed short-wave diathermy on hamstring flexibility. DESIGN AND SETTING: We used a single-blind, repeated-measures design (pretest and posttest for all treatments) that included a placebo. The 3 independent variables were treatment mode, pretest and posttest measurements, and day. Treatment...
