摘要
目的运用表面肌电与等速肌力训练仪器,就血流限制训练(BFRT)探讨对摩登舞专项学生下肢主要肌肉力量、肌肉指标等影响的情况进行分析。方法24名摩登舞专项学生随机分为无负重组、负重组及负重加压组,进行肌电、等速肌力测试仪器相关指标的测试,选取的实验动作为深蹲、弓箭蹲。结果1)负重加压组股直肌、股外侧肌、股二头肌均方根振幅值显著增加。2)负重加压组能够显著提升受试者股四头肌60°/S、180°/S角速峰值力矩、峰值功率、最大做功,提升效果显著优于无负重组和负重组。结论12周负重加压组训练对摩登舞专项学生下肢最大肌力和力量发展速率的影响效果优于无负重组和负重组。相对于传统的强度力量训练,应用血流限制训练(BFRT)可以更快地达到力量训练效果。
Objective By using surface electromyography(SEMG)and isokinetic muscle strength training equipment,the effects of blood flow restriction training(BFRT)on the main muscle strength and muscle index of lower limbs of modern dance students were analyzed.Methods 24 students of modern dance were randomly divided into three groups:no-load group,load-load group and pressure-load group.the selected experimental actions were squat and bow and arrow squat.Results The root mean square(RMS)amplitudes of rectus femoris,lateral femoris and Biceps femoris muscle increased significantly in the weight-bearing group.The group of loading pressure can significantly increase the peak torque,peak power and maximum work of quadriceps femoris muscle angular velocity at 60°/s and 180°/s,and the improvement effect is significantly better than that of the group of no loading and the group of no loading pressure.Conclusion The effect of 12-week weight-bearing group training on the maximum muscle strength and strength development rate of lower limbs of modern dance students was better than that of no-weight-bearing group and weight-bearing group.Compared with the traditional strength training,the application of blood flow restriction training(BFRT)can achieve the effect of strength training more quickly.
