目的:本研究旨在研究短跑间歇训练(SSIT)试验之间的不同休息时间对女子排球运动员生理和表现适应的影响。
方法:二十四名受过训练的大学运动员自愿参加本研究,并被随机分配到3个SSIT组,其工作与休息的比例不同(1:2[5-s运行:10-s休息],1:4[5-s运行:20-s休息],和1:6[5-s工作:30-s休息])。6周培训前后,生理参数(最大摄氧量,第一和第二通气阈值,以及峰值和平均功率输出)和物理性能测量(即,反向运动垂直跳跃,10米冲刺,和T测试方向变化速度)进行评估。
结果:训练期结束后,所有组改善(P=0.001)他们与运动相关的表现和生理参数,范围从中等到非常大的效果大小。对训练效果大小的比较分析表明,1:6SSIT组的反运动垂直跳跃变化明显更大(P=.007),10米冲刺(P=.014),峰值功率输出(P=.019),与1:2SSIT组相比,平均功率输出(P=0.05)。相比之下,与1:6SSIT组相比,1:2SSIT组的最大摄氧量变化显着(P=0.022)。然而,两组间方向变化速度和第一和第二通气阈值的变化相同(P>.05).
结论:执行SSIT时,较长的休息间隔适合物理和厌氧性能,较短的休息时间适合提高女排运动员的心肺健康水平。
OBJECTIVE: This study aimed to examine the impact of different rest periods between short sprint interval training (SSIT) trials on the physiological and performance adaptations of female volleyball players.
METHODS: Twenty-four trained college athletes volunteered to participate in this study and were randomly assigned to 3 SSIT groups with different work-to-rest ratios (1:2 [5-s run:10-s rest], 1:4 [5-s run:20-s rest], and 1:6 [5-s work:30-s rest]). Before and after 6-week training, physiological parameters (maximum oxygen uptake, first and second ventilatory thresholds, and peak and mean power output) and physical performance measures (ie, countermovement vertical jump, 10-m sprint, and T-test change-of-direction speed) were evaluated.
RESULTS: After the training period, all groups improved (P = .001) their sport-related performance and physiological parameters, ranging from moderate to very large effect sizes. Comparative analysis of the magnitude of training effects indicated that the 1:6 SSIT group had in a significantly greater change in countermovement vertical jump (P = .007), 10-m sprint (P = .014), peak power output (P = .019), and mean power output (P = .05) compared with 1:2 SSIT group. By contrast, the 1:2 SSIT group demonstrated significantly (P = .022) greater changes in maximum oxygen uptake than the 1:6 SSIT group. However, the change-of-direction speed and changes in first and second ventilatory thresholds were the same among the groups (P > .05).
CONCLUSIONS: When performing SSIT, longer rest intervals are suitable for physical and anaerobic performance, and shorter rest periods are appropriate for enhancing the cardiorespiratory fitness of female volleyball players\' performance.
