BACKGROUND:A challenge for coaches and athletes is to find the best combination of exercises during training. Considering its favorable effects, HIIT has been very popular recently. OBJECTIVE:The goal of this study was to investigate anthropometric features, performance, erythrocyte deformability,plasma viscosity (PV) and oxidative stress in response to acute and long-term (6 weeks) HIIT in adolescent basketball players. METHODS:22 sportsmen between the ages of 14–16 were included. Tabata protocol was applied to the HIIT group in addition to their routine training program 3 days/week, for 6 weeks. Erythrocyte deformability was determined using an ectacytometer (LORCA), PV with a rotational viscometer. Total oxidant status (TOS), total antioxidant status (TAS) were measured by kits. RESULTS:HIIT for 6 weeks induced an improvement in performance tests and waist circumference. 6 weeks of HIIT resulted in a decrement, while the last exercise session yielded an increment in RBC deformability. PV and TOS of HIIT groups were decreased on the 6th week. CONCLUSIONS:Our results demonstrate that, HIIT in addition to the routine exercise program is beneficial for improving performance and blood fluidity as well as decreasing oxidative stress in basketball players. Therefore, HIIT seems as an efficient training strategy for highly-trained individuals.

HIIT 通过改善血液流动性和减少氧化应激，成为篮球运动员的有效训练策略

背景：教练和运动员面临的挑战是在训练期间找到最佳的练习组合。鉴于其良好的效果，HIIT近年来非常受欢迎。目的：本研究的目的是调查青少年篮球运动员对急性和长期（6周）HIIT的人体测量特征、表现、红细胞变形性、血浆粘度（PV）和氧化应激。方法：纳入 22 名 14-16 岁的运动员。除了每周 3 天的常规训练计划外，HIIT 组还应用 Tabata 方案，持续 6 周。红细胞可变形性使用具有旋转粘度计的扭力计(LORCA)、PV来测定。通过试剂盒测量总氧化状态（TOS）、总抗氧化状态（TAS）。结果：6 周的 HIIT 改善了体能测试和腰围。6 周的 HIIT 导致红细胞变形能力下降，而最后一次锻炼则导致红细胞变形能力增加。HIIT组的PV和TOS在第6周下降。结论：我们的结果表明，除了常规锻炼计划外，HIIT 有利于提高篮球运动员的表现和血液流动性以及减少氧化应激。因此，对于训练有素的人来说，HIIT 似乎是一种有效的训练策略。
