Background: Surfing is a sport that requires alternating high, medium, and low intensity at one time. combines three phases, namely paddling, pop-up, wave-ride. The surf pop-up phase characterized by change from paddling position to standing on the surfboard in dynamic motion. During this transition, surfer must move 75% of his body weight less than second. Pop-up movement unique challenge for ...
BACKGROUND It is important to understand the characteristics of amputee gait to develop more functional prostheses. The aim of this study is to quantitatively evaluate amputee gait by dynamic analysis of the musculoskeletal system during level walking and stair climbing. METHODS Dynamic analysis using gait analysis, electromyography and musculoskeletal modeling for above-knee amputees (n=8) a...
It is thought that time to peak torque and joint angle at parameters provide important data for the functional evaluation of quadriceps hamstring muscles. known studies with these are rare in literature. The aim this study investigate relationship between hamstring/quadriceps (H/Q) ratio, female football players. sample group consisted 20 footballers performing national women's league (3rd Divi...
Background: Low back pain (LBP) is a one of the most common symptoms of vertebral column diseases. Spinal muscles have a outstanding role in maintaining vertebral column function in daily life. But proper function and motion of hip and knee joints also has an important role in performing smooth, fine and nonstressed movements of lumbar spin. Where as accurate and fine motions of hip and knee jo...
Background and purpose: Ultrasonography is a reliable and valid method to assess the strength of neck extensors and measuring the neck muscles dimensions. Cervical muscles strength and dimensions may change in different positions. The aim of this study was to compare the strength of cervical extensor muscles and dimensions of semi-spinalis capitis muscle (SECM) in three different neck positions...
The aim of this study is the effect of one period core stability exercise with and without kinesio taping on biomechanical effective factors in lower cross syndrome on female. 36 female between 30 to 40 were randomly divided in to 3 groups (control, with taping and without taping). each group consist 12 participant. To measure Pelvic slope, Hip and Knee ROM, Isometric strength of flexors and e...
Underground coal miners who work in low-seam mines frequently handle materials in kneeling or squatting postures. To assess quadriceps and hamstring muscle demands in these postures, nine participants performed lateral load transfers in kneeling and squatting postures, during which electromyographic (EMG) data were collected. EMG activity was obtained at five points throughout the transfer for ...
