This study was aimed to: (1) investigate the effects of physiological functions of sprint interval training (SIT) on the aerobic capacity of elite badminton players; and (2) explore the potential mechanisms of oxygen uptake, transport and recovery within the process. Thirty-two elite badminton players volunteered to participate and were randomly divided into experimental (Male-SIT and Female-SIT group) and control groups (Male-CON and Female-CON) within each gender. During a total of eight weeks, SIT group performed three times of SIT training per week, including two power bike trainings and one multi-ball training, while the CON group undertook two Fartlek runs and one regular multi-ball training. The distance of YO-YO IR2 test (which evaluates player's ability to recover between high intensity intermittent exercises) for Male-SIT and Female-SIT groups increased from 1083.0 ± 205.8 m to 1217.5 ± 190.5 m, and from 725 ± 132.9 m to 840 ± 126.5 m ( < 0.05), respectively, which were significantly higher than both CON groups ( < 0.05). For the Male-SIT group, the ventilatory anaerobic threshold and ventilatory anaerobic threshold in percentage of VOmax significantly increased from 3088.4 ± 450.9 mL/min to 3665.3 ± 263.5 mL/min ( < 0.05),and from 74 ± 10% to 85 ± 3% ( < 0.05) after the intervention, and the increases were significantly higher than the Male-CON group ( < 0.05); for the Female-SIT group, the ventilatory anaerobic threshold and ventilatory anaerobic threshold in percentage of VOmax were significantly elevated from 1940.1 ± 112.8 mL/min to 2176.9 ± 78.6 mL/min, and from 75 ± 4% to 82 ± 4% ( < 0.05) after the intervention, which also were significantly higher than those of the Female-CON group ( < 0.05). Finally, the lactate clearance rate was raised from 13 ± 3% to 21 ± 4% ( < 0.05) and from 21 ± 5% to 27 ± 4% for both Male-SIT and Female-SIT groups when compared to the pre-test, and this increase was significantly higher than the control groups ( < 0.05). As a training method, SIT could substantially improve maximum aerobic capacity and aerobic recovery ability by improving the oxygen uptake and delivery, thus enhancing their rapid repeated sprinting ability.
（1）探讨冲刺间歇训练（SIT）对优秀羽毛球运动员有氧能力的生理功能影响；（2）探讨摄氧量、运输和恢复过程中的潜在机制。32 名优秀羽毛球运动员自愿参加，并按性别分为实验组（男性-SIT 和女性-SIT 组）和对照组（男性-CON 和女性-CON 组）。在总共八周的时间里，SIT 组每周进行三次 SIT 训练，包括两次功率自行车训练和一次多球训练，而 CON 组则进行两次法特莱克跑和一次常规多球训练。男性-SIT 和女性-SIT 组的 YO-YOIR2 测试（评估运动员在高强度间歇运动之间恢复的能力）距离从 1083.0 ± 205.8m 增加到 1217.5 ± 190.5m，从 725 ± 132.9m 增加到 840 ± 126.5m（<0.05），均显著高于 CON 组（<0.05）。对于男性-SIT 组，通气无氧阈和通气无氧阈占 VOmax 的百分比分别从 3088.4 ± 450.9mL/min 增加到 3665.3 ± 263.5mL/min（<0.05），从 74 ± 10%增加到 85 ± 3%（<0.05），干预后均显著高于男性-CON 组（<0.05）；对于女性-SIT 组，通气无氧阈和通气无氧阈占 VOmax 的百分比分别从 1940.1 ± 112.8mL/min 增加到 2176.9 ± 78.6mL/min，从 75 ± 4%增加到 82 ± 4%（<0.05），干预后均显著高于女性-CON 组（<0.05）。最后，男性-SIT 和女性-SIT 组的乳酸清除率分别从 13 ± 3%增加到 21 ± 4%（<0.05）和从 21 ± 5%增加到 27 ± 4%，与预测试相比，这一增长明显高于对照组（<0.05）。作为一种训练方法，SIT 通过提高摄氧量和输送能力，显著提高最大有氧能力和有氧恢复能力，从而提高其快速重复冲刺能力。
