Abstract：
Present study aimed to compare the effects of SSIT intervention with varying rest distributions on hormonal, physiological, and performance adaptations in soccer players. Thirty-six players were randomly divided into three SSIT groups, each performing 4 sets of 6-10 repetitions of 6-second all-out running with rest intervals at ratios of 1:3, 1:6, and 1:9. Prior to and following the 7-week training period, aerobic fitness indices and anaerobic power were evaluated using a graded exercise test with a gas collection system and a lower-body Wingate test, respectively. Also, sport-specific bio-motor abilities were determined by measuring vertical jump, 20-m sprint, and T-test change of direction speed, Yo-Yo IR1 and maximal kicking distance. Hormonal status was also monitored by evaluating testosterone and cortisol levels. Following the 7-week training period, all SSIT interventions resulted in significant enhancements (p < 0.05) in soccer-related performance, physiological parameters, and hormonal adaptations, exhibiting effect sizes that ranged from small to large. Comparative analysis indicated that the 1:9 SSIT results in greater adaptive responses (p < 0.05) in the vertical jump, peak power, testosterone, and cortisol compared to the 1:3 SSIT group. By contrast, the 1:3 SSIT group induced more adaptive responses (p < 0.05) in the mean power output, maximum oxygen consumption (V̇O2max), and Yo-Yo IR1 compared to the 1:9 SSIT group. Hence, for enhancing physical performance, especially vertical jump height, anaerobic peak power, and hormonal adaptations, the 1:9 SSIT ratio is preferable. Conversely, shorter rest intervals (specifically, the 1:3 SSIT ratio) are better suited for eliciting heightened adaptive responses in mean power output, V̇O2max, and Yo-Yo IR1 over the 7-week training period among young male soccer players.
摘要：
本研究旨在比较SSIT干预与不同休息分布对荷尔蒙的影响，生理,和足球运动员的表现适应。36名选手被随机分为3个SSIT组,每个人都以1:3、1:6和1:9的比率进行4组6-10次重复的6秒全力以赴的跑步。在7周培训之前和之后，使用带有气体收集系统的分级运动测试和下半身Wingate测试评估了有氧适应度指数和无氧能力，分别。此外，运动特定的生物运动能力是通过测量垂直跳跃来确定的，20米冲刺,和T-测试方向的速度变化，Yo-YoIR1和最大踢距离。还通过评估睾酮和皮质醇水平来监测激素状态。经过7周的培训，所有SSIT干预措施均显著提高(p<0.05)与足球相关的表现，生理参数,和荷尔蒙的适应，表现出从小到大的效果大小。比较分析表明，1:9SSIT在垂直跳跃中产生了更大的适应性反应(p<0.05)，峰值功率,睾丸激素，和皮质醇与1：3SSIT组相比。相比之下,1:3SSIT组在平均功率输出上引起更多的适应性反应(p<0.05)，最大耗氧量（V²O2max），和Yo-YoIR1与1：9SSIT组相比。因此，为了提高物理性能，尤其是垂直跳跃高度，无氧峰值功率，和荷尔蒙的适应，1:9的SSIT比率是优选的。相反，较短的休息间隔(具体地说，1：3SSIT比率)更适合在平均功率输出中引起增强的自适应响应，V♪O2max,和Yo-YoIR1在年轻男性足球运动员的7周训练期间。
