تأثير برنامج تدريبي باستخدام طريقة تقييد تدفق الدم و دور جين (VEGF)‎ على القوة العضلية للاعبي دفع الجلة

Abstract EN

The blood flow restricted training is showing by internal circulation between the neuro-muscular and cardiorespiratory system, and combination with unique technique with others sports like track and field needs more power, strength and speed movement lead to feel fatigue or muscular exhaustion after a certain period of muscular exertion which represents over load upon neuron muscular system, as a result, some of the muscular tissues begin to rupture slightly, accompanied by in sufficiency in blood flow to the muscle, and in turn in sufficiency in muscular oxygen, at this stage, the vascular endothelial cells start to secrete vascular endothelial growth factor (VEGF) to increased blood flow and oxygen in muscles.

the aim : of the current research was to study the effect of band blood restricted training (8 weeks, 3 times per week) on muscle strength, VEGF gene and shot put for athletes methods : thirteen female athletes (from 19 to 21 years) performed band blood restricted training with external weight at each hand and legs, they underwent an assessment of health state before testing and starting the exercise program controlled in the same training session for trained 2-month, three times a week, for 8 weeks at (50% to 75%), 50 min per session under the supervision of a personal trainer, to determine changes in components of muscle strength, vegf gene and shot put for long distance.

result: the result were obtained from all athletes between pre and post blood flow restricted training for the post measurement for all variables vegf, muscle strength, shot put for athletes .

t-test for paired samples was performed to compare both time points (level of significance p<0.05).

conclusion: two month of regular training program by use of the method blood flow restricted (8 weeks, 3 times per week) improved muscle strength for legs.

back and hand grip, shot put for long distance and VEGF gene for athletes
