This study analyzed the effect of 4 weeks of jumping interval training (JIT), included in endurance training, on neuromuscular and physiological parameters. Eighteen recreational runners, randomized in control and experimental groups, performed 40 min of running at 70% of velocity at peak oxygen uptake, for 3 times per week. Additionally, the experimental group performed the JIT twice per week, which consisted of 4 to 6 bouts of continuous vertical jumps (30 s) with 5-min intervals. Three days before and after the training period, the countermovement (CMJ) and continuous jump (CJ30), isokinetic and isometric evaluation of knee extensors/flexors, progressive maximal exercise, and submaximal constant-load exercise were performed. The JIT provoked improvement in neuromuscular performance, indicated by (i) increased jump height (4.7%; effect size (ES) = 0.99) and power output (≈ 3.7%; ES ≈ 0.82) of CMJ and rate of torque development of knee extensors in isometric contraction (29.5%; ES = 1.02); (ii) anaerobic power and capacity, represented by the mean of jump height (7.4%; ES = 0.8), and peak power output (PPO) (5.6%; ES = 0.73) of the first jumps of CJ30 and the mean of jump height (10.2%, ES = 1.04) and PPO (9.5%, ES = 1.1), considering all jumps of CJ30; and (iii) aerobic power and capacity, represented by peak oxygen uptake (9.1%, ES = 1.28), velocity at peak oxygen uptake (2.7%, ES = 1.11), and velocity corresponding to the onset of blood lactate accumulation (9.7%, ES = 1.23). These results suggest that the JIT included in traditional endurance training induces moderate to large effects on neuromuscular and physiological parameters.
本研究分析了耐力训练中的4周跳跃间歇训练（JIT）对神经肌肉和生理参数的影响。18名休闲跑步者被随机分为对照组和实验组，以最大摄氧量时速度的70%进行40分钟跑步，每周3次。此外，实验组每周进行两次JIT，包括4至6组连续垂直跳跃（30秒），每组间隔5分钟。在训练期前后三天，进行了反向运动跳（CMJ）和连续跳跃（CJ30）、膝关节伸肌/屈肌的等速和等长评估、递增最大运动和次最大恒定负荷运动。JIT使神经肌肉性能得到改善，表现为：（i）CMJ的跳跃高度增加（4.7%；效应量（ES）=0.99）和功率输出（约3.7%；ES≈0.82）以及等长收缩时膝关节伸肌的扭矩发展速率（29.5%；ES=1.02）；（ii）无氧功率和能力，以CJ30第一次跳跃的跳跃高度平均值（7.4%；ES=0.8）和峰值功率输出（PPO）（5.6%；ES=0.73）以及考虑CJ30所有跳跃的跳跃高度平均值（10.2%，ES=1.04）和PPO（9.5%，ES=1.1）来表示；（iii）有氧功率和能力，以最大摄氧量峰值（9.1%，ES=1.28）、最大摄氧量时速度（2.7%，ES=1.11）以及血乳酸积累起始对应的速度（9.7%，ES=1.23）来表示。这些结果表明，传统耐力训练中的JIT对神经肌肉和生理参数产生中度至较大影响。
