Abstract

One study to date has compared inter-repetition rest intervals when employing ‘composite’ training. Thus, the purpose of this study was to compare the acute effects of 2-, 3- and 4-mins ‘composite’ training inter-repetition rest intervals on fast stretch shortening cycle (SSC) and neuromuscular performance. A randomized crossover research design was employed. Drop jump (DJ), 20m sprint (with 5 and 10m splits), countermovement jump (CMJ) and isometric mid-thigh pull (IMTP) tests were performed pre-session, post-session, and 7 days post-session to observe if supercompensation occurred. A 2-min rest interval showed enhancements in fast SSC DJ performance where supercompensation may have occurred in height, velocity, force and power (Cohen’s d = 0.22-0.55). A 3-minute rest interval elicited responses in 5 and 20m sprint performance (Cohen’s d = -0.29 to -0.30) and isometric RFD (Cohen’s d = 0.35-0.60) 7 days post-session. CMJ measures (Cohen’s d = 0.22-0.76) appeared to have experienced supercompensation when employing a 4-minute rest period. Significant (p < 0.05) decreases in performance pre- to post-session were found for certain sprint, CMJ and IMTP variables. The ‘composite’ training inter-repetition rest interval used, appears dependent on the primary goal of a training cycle. However, a 3-min rest interval may be used if there are multiple goals of a training cycle due to enhancements in sprint performance, isometric RFD and CMJ height. ‘Composite’ training is a time-efficient method of enhancing jump, sprint, and maximal strength, which is suitable for practitioners working in sports such as hurling where time is limited.
在 "复合 "训练中,不同的重复间休息时间间隔对快速拉伸-缩短周期和冰壶运动员神经肌肉表现的急性影响:试点研究
迄今为止,只有一项研究对采用 "复合 "训练时的重复间歇进行了比较。因此,本研究旨在比较 2 分钟、3 分钟和 4 分钟 "复合 "训练间歇对快速拉伸缩短周期(SSC)和神经肌肉表现的急性影响。研究采用了随机交叉研究设计。在训练前、训练后和训练后 7 天分别进行了落差跳(DJ)、20 米冲刺(5 米和 10 米间隔)、反向运动跳(CMJ)和等长大腿中部牵拉(IMTP)测试,以观察是否出现了超补偿。2 分钟的休息间歇显示出快速 SSC DJ 性能的提高,在高度、速度、力量和功率方面可能出现了超补偿(Cohen's d = 0.22-0.55)。3 分钟的休息间歇会在训练后 7 天引起 5 米和 20 米短跑成绩(Cohen's d = -0.29 至 -0.30)和等长 RFD(Cohen's d = 0.35-0.60)的反应。在使用 4 分钟休息时间时,CMJ 测量(Cohen's d = 0.22-0.76)似乎出现了超补偿。某些短跑、CMJ 和 IMTP 变量的成绩在训练前和训练后有显著下降(p < 0.05)。所使用的 "综合 "训练间歇似乎取决于训练周期的主要目标。但是,如果一个训练周期有多个目标,则可以使用 3 分钟的休息间歇,因为这样可以提高短跑成绩、等长射频分配和 CMJ 高度。复合 "训练是一种提高跳跃、冲刺和最大力量的省时方法,适合从事时间有限的运动项目(如投掷)的练习者。
