[Purpose] The present study aimed to determine changes in muscle activity while moving on a treadmill at various speeds. [Subjects] The activities of the left vastus lateralis, vastus medialis, hip adductors, lateral head of gastrocnemius, medial head gastrocnemius, soleus, and tibialis anterior of 10 healthy male university students were analyzed. [Methods] University students walked, jogged, ...

While running on uneven ground, humans are able to negotiate visible but also camouflaged changes in ground level. Previous studies have shown that the leg kinematics before touch down change with ground level. The present study experimentally investigated the contributions of visual perception (visual feedback), proprioceptive feedback and feed-forward patterns to the muscle activity responsib...

Introduction: The study aimed to investigate the onset time and the electromyographic activity level of the selected lower limbs muscles in active and inactive aged women. Methods: in this case-control study, 28 aged women with a mean age of 61.07±0.88 were selected in two groups of inactive (15 people) and active (13 people). The electrical activity of the selected muscles of the lower l...

conclusions the study findings indicate that short-term exercises had no significant effect on the ratio of vmo to vl muscle fiber angles in patients with pfps. results there were no significant differences in the muscle strength and fiber angle of the vmo, vl oblique and longus muscles after training between the control and experimental groups (p > 0.05). patients and methods thirty-five subje...

BACKGROUND Published data regarding the structure of the quadriceps tendon are diverse. Dissection of the quadriceps muscle group revealed that beside the rectus femoris, vastus lateralis, vastus intermedius and vastus medialis a fifth muscle component- named the tensor vastus intermedius consistently fused into quadriceps tendon. It can be hypothesized that all these elements of the extensor a...
