Abstract：
BACKGROUND Basketball is a sport with a global impact and recognized major leagues, and is one of the most studied and analyzed sports for improvement at the level of the high-performance athlete. Increasing the jump height of basketball players is an essential factor for high athletic performance. MATERIAL AND METHODS This study aimed to identify the effect of low-intensity training with flow restriction versus the eccentric exercise protocol on amateur athletes. Eighteen amateur basketball players aged 16-45 years were divided into 2 groups: Group A consisted of 9 participants with low-intensity training with flow restriction (40% intensity) with 200 mmHg occlusion applying flow restriction bands in the popliteal area, while Group B consisted of 9 participants who performed an eccentric exercises protocol on the gastrocnemius. An anthropometric evaluation was applied, which consisted of perception of effort, range of movement (ROM), muscle strength intensity, and the power of the jump measured with a jump platform. RESULTS Notable changes were observed in favor of Group A for the right dorsiflexion, with mean difference (MD)=-2.444 (P=0.018); left dorsiflexion with MD=-2.778 (P=0.027) and left foot perimeter variable with MD=-0.667 (P=0.026) at 95% confidence interval (CI); while the vertical jump was in favor of Group B, with MD=-2.899 (P=0.006). CONCLUSIONS Low-intensity training with flow restriction and eccentric exercise protocol were both effective in improving jumping performance. A significant improvement was shown in the jump height and ROM of the 2 study groups.
摘要：
背景技术篮球是一项具有全球影响力和公认的大联盟的运动。并且是在高性能运动员水平上进行改进的研究和分析最多的运动之一。提高篮球运动员的跳跃高度是提高运动员运动成绩的重要因素。材料和方法本研究旨在确定流量限制的低强度训练与偏心运动方案对业余运动员的影响。18名年龄在16-45岁之间的业余篮球运动员分为2组：A组由9名参与者组成，他们进行了低强度训练，并进行了流量限制（40％强度），并在the区施加了200mmHg的阻塞，B组由9名参与者组成，他们在腓肠肌上进行了偏心运动。进行了人体测量评估，包括对努力的感知，运动范围（ROM），肌肉力量强度，用跳跃平台测量跳跃的力量。结果观察到明显的变化有利于A组的右背屈，平均差（MD）=-2.444（P=0.018）；在95％置信区间（CI）下，左背屈时MD=-2.778（P=0.027），左脚周长变量MD=-0.667（P=0.026）；而垂直跳跃有利于B组，MD=-2.899（P=0.006）。结论流量限制和偏心运动方案的低强度训练均可有效改善跳跃表现。2个研究组的跳跃高度和ROM显着改善。
