Sprint interval training (SIT) is a potent exercise strategy to enhance athletes' aerobic capacity in a time-efficient manner. The purpose of this study was to examine the effect of a low-volume court-based SIT program on aerobic capacity and sport-specific endurance performance for competitive tennis players. Sixteen competitive collegiate tennis players were randomly assigned to the SIT (court-based repeated-sprint training) and traditional endurance training (ET; 45-min continuous treadmill running) groups for a 6-week intervention (3 sessions/week). The maximal oxygen uptake ( O), minute ventilation at peak exercise (VEmax), ventilatory anaerobic threshold in percentage of O (VT/VO), and elimination rate of blood lactate (BLA) were assessed, whereas the Yo-Yo Intermittent Recovery Test Level 2 (YoYo-IR2) and the tennis-specific HIT&TURN test were conducted at baseline and after the intervention. Both SIT and ET showed significant improvements in O (p < 0.01) with moderate effect sizes (ES = 0.64 and 0.98, respectively), as well as in VE (p < 0.01) with small effect sizes (ES = 0.23 and 0.21, respectively), and VT/VO (p < 0.01) with large effect sizes (ES = 2.37 and 3.85, respectively). The BLA improved significantly in SIT (ES = 1.03; p < 0.05) whereas no significant changes occurred in ET. The magnitude-based decision showed a clear and superior improvement in both YoYo-IR2 (ES = 0.69) and HIT&TURN (ES = 1.72) tests in SIT than ET. Compared with traditional ET, court-based SIT can be a time-efficient strategy to improve aerobic capacity and tennis-specific endurance without requiring specialized equipment for competitive tennis players.
冲刺间歇训练（SIT）是一种有效的训练策略，能够高效地提升运动员的有氧能力。本研究旨在探讨低强度的基于球场的SIT训练计划对竞技网球运动员有氧能力和专项运动耐力表现的影响。16名竞技大学生网球运动员被随机分为SIT组（基于球场的重复冲刺训练）和传统耐力训练（ET组；45分钟持续跑步机跑步），进行为期6周的干预（每周3次训练）。评估了最大摄氧量（ O）、运动峰值时的分钟通气量（VEmax）、 O百分比的通气无氧阈值（VT/VO）以及血乳酸消除率（BLA），同时在基线和干预后进行了Yo-Yo间歇恢复测试2级（YoYo-IR2）和网球专项HIT&TURN测试。SIT组和ET组的 O均有显著改善（p < 0.01），效应量中等（分别为ES = 0.64和0.98），VE也有显著改善（p < 0.01），效应量较小（分别为ES = 0.23和0.21），VT/VO同样有显著改善（p < 0.01），效应量较大（分别为ES = 2.37和3.85）。SIT组的BLA有显著改善（ES = 1.03；p < 0.05），而ET组无显著变化。基于效应量的判定显示，SIT组在YoYo-IR2（ES = 0.69）和HIT&TURN（ES = 1.72）测试中的改善明显优于ET组。与传统ET相比，基于球场的SIT对于竞技网球运动员来说，是一种无需专门设备就能高效提高有氧能力和网球专项耐力的策略。
