This study aimed to evaluate the effects of low-intensity blood flow restriction (BFR) training and high-intensity resistance training (HI-RT) on the leaping performance of long-jumpers.
Long jump players were divided into two groups; one group (group A) receiving HI-RT (n = 8) and the other group (group B) receiving combined low-intensity BFR training plus HI-RT (n = 8). Muscle power and knee muscle strength was assessed at baseline, 3 weeks and 6 weeks of intervention.
1-RM was found to be significantly different between Group A and Group B at 3 and 6 weeks. Further, IKDQR, IKDHR and IKDQL was significantly improved in group B as compared to group A both at 3 and 6 weeks. There was significant time effect, group effect and time-group interaction in the strength of quadriceps and hamstring of both left and right leg measured through isokinetic device. Post-hoc analysis for 1-RM in group B showed a significant improvement at baseline and 6 weeks and the broad jump was significant at baseline and 3 weeks and at baseline and 6 weeks.
The combined effects of low-intensity BFR training and HI-RT is effective in improving the muscle strength and power of lower limbs in long jumpers.
本研究旨在评估低强度血流限制（BFR）训练和高强度阻力训练（HI-RT）对跳远运动员跳跃成绩的影响。
将跳远运动员分为两组；一组（A组）接受HI-RT训练（n = 8），另一组（B组）接受低强度BFR训练加HI-RT联合训练（n = 8）。在干预的基线、3周和6周时评估肌肉力量和膝关节肌肉力量。
在3周和6周时，发现A组和B组之间的1-RM有显著差异。此外，与A组相比，B组在3周和6周时的IKDQR、IKDHR和IKDQL均有显著改善。通过等速装置测量的左右腿股四头肌和腘绳肌力量存在显著的时间效应、组间效应和时间-组间交互作用。B组1-RM的事后分析显示在基线和6周时有显著改善，立定跳远在基线和3周以及基线和6周时显著。
低强度BFR训练和HI-RT的联合作用可有效提高跳远运动员下肢的肌肉力量和功率。
