Snapping of the medial hamstrings is a rare condition, with few cases reported throughout the literature. The snapping sensation reportedly occurs when a hamstring tendon passes over the medial tibial condyle, a muscle belly, or another tendon. The semitendinosus tendon is frequently involved, but concomitant involvement of the semitendinosus and gracilis tendons has also been described. Althou...

In recent time, the specialists in field of physical education and health protection have no consensus on need to include stretching exercises as an obligatory type activity for apparently healthy young people. The problem is that most university students tend sedentary lifestyle. According some reports, this can negatively affect flexibility hamstrings and, a result, lead decrease performance....

Recently, a training program that includes perturbation of support surfaces has been shown to allow most active individuals with ACL injury who pass a screening examination to successfully return to high level activities. The purpose of this study was to identify the effect of this rehabilitation program on involved side muscle activation during walking in subjects with acute ACL rupture and to...

BACKGROUND The purpose of this study was to elucidate relationships between quadriceps and hamstrings voluntary muscle fatigue and upper motor lesion impairments in cerebral palsy in order to gain a better understanding of their contribution to the observed fatigue resistance. METHODS Seventeen ambulatory subjects with cerebral palsy (mean age: 17.0, SD=4.8 years) were recruited. Quantitative...

It is well recognised that the hamstrings are susceptible to acute strain injury during high-speed running. However, the particular phase of the sprinting gait cycle at which hamstring injury occurs remains a debated topic. Video footage and athlete anecdotes have contributed to the discussion, but do not provide suffi cient temporal resolution to fully answer the question. In this paper, we br...

Objective: The main goal of the athletes who undergo anterior cruciate ligament reconstruction (ACLR) surgery is a successful return-to-sport. At this stage, identifying muscular deficits becomes important. Hence, in study, three discriminative features based on surface electromyographic signals (sEMG) acquired dynamic protocol are introduced to assess damping ability and interpret activation p...

in this study, the recycling possibility of residual oil fly ash (rofa) towards preparing activated carbon and its application in environmental remediation through adsorbing cu (ii) and pb (ii) ions from aqueous solutions were investigated. activated carbons were prepared using two different physical activation methods such as under steam flow at 950 0c, and combined steam and co2 flow at 850 0...

The role of the biarticular muscles is a topic that has received considerable attention however their function is not well understood. In this paper, we argue that an analysis that is based upon considering the effect of the biarticular muscles on the segments that they span (rather than their effect on joint rotations) can be illuminating. We demonstrate that this understanding is predicated o...
