跑步搭配下肢加压对网球运动员运动表现的影响研究

探讨以跑步搭配下肢加压的方式进行热身(running exercise combined with KAATSU training,RE-KT)对网球运动员运动表现和生理反应的影响.招募20名大学生男性网球运动员,采用平衡次序分配至两种实验干预,1)跑步(50%最大心率,进行5组,每组120s,组间休息1min)搭配下肢加压(加压部位为股四头肌、腘胂肌群,加压压强为150mmgh)进行热身(RE-KT);2)单纯跑步热身活动(running exercise,RE).结果表明,在心率与运动自觉量表值方面,受试者接受RE-KT实验干预后指标显著高于RE干预后指标(p0.05);在血乳酸、睾酮、生长激素浓度方面,受试者接受RE-KT实验干预后指标显著高于RE干预后指标(p0.05);在爆发力和最大力矩方面,受试者接受RE-KT实验干预后指标显著高于RE干预后指标(p0.05).但在肌耐力方面,受试者接受RE-KT实验干预后指标与接受RE干预后指标差异无统计学意义(p0.05).得出利用跑步搭配下肢加压的方式对网球运动员进行热身能够诱发心率上升、RPE值增加、血乳酸、睾酮、生长激素浓度累积等生理效应,并且能够促进下肢爆发力和最大力矩的表现,但对肌耐力的运动表现没有显著改善作用.

Effects of Running Exercise Combined with of Lower KAATSU Training on Sports Performance of Tennis Athletes

In this paper, researches have been done to investigate the effects of running exercise combined with KAATSU training (RE-KT) on the performance and physiological responses of tennis athletes. Twenty college male tennis players were enrolled and assigned to two experimental interventions in a balanced order:1) running (50% maximal heart rate, 5 in each group, 120s in group with 1min rest) with lower extremity compression parts of the quadriceps, thigh muscles, pressure is 150mmgh) warm-up; 2) pure running warm-up activity (running exercise, RE). Results show that, in the heart rate and exercise-conscious scale, the index of subjects receiving RE-KT intervention was significantly higher than that of RE after intervention (p<0.05). In terms of blood lactate, testosterone and growth hormone concentration, The indexes of -KT after intervention were significantly higher than those of RE after intervention (p<0.05). However, in terms of explosive force and maximum torque, the index of RE subjects receiving RE-KT intervention was significantly higher than that of RE subjects (p<0.05), but in endurance of muscle, After receiving RE intervention there was no significant difference (p>0.05). It is concluded that running warm-up of tennis players by running with leg compression can induce physiological effects such as increase of heart rate, increase of RPE, accumulation of blood lactate, testosterone and growth hormone concentration, and promote the performance of lower limbs explosive force and maximum torque. However, No significant improvement in motor performance of muscular endurance.
