The purpose of this study was to investigate the effect of sprint interval training (SIT) compared to control group (CG). 29 Judoists were assigned to SIT group (n=11, age 20.00±1.10 years) and CG (n=18, age 19.94±1.16 years). There were no significant changes in body fat and aerobic performance (VO2max, HRmax, and HR after Judo match) after 4 and 8 weeks. However, anaerobic peak power and mean power in SIT group was significantly increased by 16% and 17% at 4 weeks and by 17% and 22% at 8 weeks compared to baseline values (p<0.05). At 8 weeks, blood lactate concentration after graded exercise was significantly decreased in SIT group compared to CG after 10 and 15 min of recovery (p< 0.05). After Judo match, triglyceride and epinephrine were significantly increased in CG compared to SIT group (p<0.05) at 4 and 8 weeks. Otherwise, there were no significant changes of total cholesterol, albumin, FFA, and norepinephrine in both groups. We suggested that SIT program for elite Judoists would be effective to increase anaerobic power in a short period during off-season training.
本研究旨在探究冲刺间歇训练（SIT）与对照组（CG）的效果差异。29 名柔道运动员被分配到 SIT 组（n=11，年龄 20.00±1.10 岁）和 CG（n=18，年龄 19.94±1.16 岁）。经过 4 周和 8 周的训练，SIT 组和 CG 的体脂和有氧表现（最大摄氧量、最大心率和柔道比赛后的心率）均无显著变化。然而，SIT 组的无氧峰值功率和平均功率在第 4 周分别提高了 16%和 17%，在第 8 周分别提高了 17%和 22%，与基线值相比具有显著差异（p<0.05）。第 8 周时，SIT 组在恢复 10 分钟和 15 分钟后，分级运动后的血乳酸浓度与 CG 相比显著降低（p<0.05）。4 周和 8 周时，CG 组的甘油三酯和肾上腺素水平与 SIT 组相比显著升高（p<0.05）。然而，两组的总胆固醇、白蛋白、FFA 和去甲肾上腺素均无显著变化。本研究表明，对于精英柔道运动员来说，SIT 方案在淡季训练期间可以在短时间内有效提高无氧能力。
