Abstract

Purpose: The aim of this study was to investigate the effects of repeated-sprint training in hypoxia (RSH) versus in normoxia (RSN) in female national-level rugby union players.

Methods: In a randomized, controlled, and crossover study, 8 female rugby union players performed 5 sessions of repeated sprints either in normobaric hypoxia (RSH, simulated altitude: 3000 m; FiO2 = 14.5%) or in normoxia (RSN, terrestrial altitude: 165 m; FiO2 = 20.5%). Before (Pre) and after (Post) training, repeated-sprint ability (6 × 10-s "all-out" sprints and 20-s recovery) was evaluated on a cycle ergometer.

Results: From Pre to Post, peak power output was improved in RSH (602 [98] vs 704 [92] W; P = .007) but not in RSN (661 [91] vs 673 [76] W; P = .560). Similarly, mean power output was enhanced in RSH (445 [63] vs 532 [51] W; P = .013) but not in RSN (499 [88] vs 509 [63] W; P = .557). Sprint decrement did not change in either RSH (24.5 [8.9] vs. 24.0% [5.7%]; P = .819) or RSN (22.7 [5.9] vs 24.3% [4.8%]; P = .336).

Conclusion: As few as 5 sessions of RSH were beneficial for improving peak and mean power outputs during repeated-sprint exercise in female national-level rugby union players compared with the same training in normoxia.

低氧条件下重复冲刺训练对国家级橄榄球联盟女运动员的影响。

目的：本研究的目的是探讨在低氧（RSH）和常氧（RSN）条件下重复短跑训练对国家级橄榄球联盟女运动员的影响。方法：在一项随机、对照和交叉研究中，8名女子橄榄球联盟运动员在常压缺氧（RSH，模拟海拔：3000 m， FiO2 = 14.5%）和常压缺氧（RSN，地面海拔：165 m， FiO2 = 20.5%）条件下进行了5次重复短跑。在训练前（Pre）和训练后（Post），用循环力计评估重复冲刺能力（6 × 10-s“全力”冲刺和20-s恢复）。结果：从术前到术后，RSH （602 [98] vs 704 [92] W, P = .007）的峰值功率输出有所改善，但RSN （661 [91] vs 673 [76] W, P = .560）的峰值功率输出没有改善。同样，RSH的平均功率输出增加（445 [63]vs 532 [51] W; P = 0.013），但RSN没有（499 [88]vs 509 [63] W; P = 0.557）。RSH （24.5 [8.9] vs. 24.0% [5.7%]; P = .819）和RSN （22.7 [5.9] vs. 24.3% [4.8%]; P = .336）的Sprint减量均无变化。结论：5次RSH较低氧条件下的相同训练更有利于提高国家级橄榄球联盟女运动员重复冲刺运动中的峰值和平均功率输出。
