【摘要】：目的:探讨低氧反复冲刺训练对篮球运动员速度耐力的影响。方法:16名篮球运动员分为低氧组和常氧组,每组各8人。低氧组和常氧组分别在模拟海拔3000米的低氧环境中和常氧环境中用无氧功率自行车进行反复冲刺训练,每周2次,共计4周。反复冲刺训练前后,两组受试者在常氧环境中进行折返跑测试和Wingate无氧功测试,折返跑测试后分别在即刻、3 min、5 min、7 min、9 min等时间点进行血液采集,测量血乳酸值。记录折返跑成绩、Wingate无氧功测试的相对平均功率,并对数据进行统计分析。结果:与训练前相比,4周反复冲刺训练后,低氧组和常氧组的折返跑成绩均显著提高(P0.05),但两组间无显著性差异(P0.05);低氧组的血乳酸清除速率高于常氧组的,且在7分钟时间点有极显著差异(P0.01);低氧组的相对平均功率有显著性提高(P0.05),常氧组的相对平均功率无显著性变化(P0.05),两组间的相对平均功率无显著性差异。结论:反复冲刺训练可以提高篮球运动员的速度耐力,低氧反复冲刺训练可以有效提高篮球运动员机体乳酸清除能力,这种有氧能力的提升有助于运动员在比赛中更好地发挥。
[Abstract]:Objective: to investigate the effect of hypoxic repeated sprint training on speed endurance of basketball players.Methods Sixteen basketball players were divided into hypoxia group and normoxic group with 8 players in each group.The hypoxic and normoxic groups were sprinted twice a week for a total of 4 weeks in hypoxic and normoxic environments at simulated altitude of 3000 m and in normoxic environment respectively.Before and after repeated sprint training, the subjects in both groups were tested for reentry run and Wingate anaerobic work in normoxic environment. The blood samples were collected at 3 minutes and 5 minutes and 7 minutes and 9 min immediately after the test. The blood lactic acid values were measured.The relative average power of Wingate anaerobic power test was recorded and the data were statistically analyzed.Results: after repeated sprint training for 4 weeks, the scores of reverse run in hypoxia group and normoxic group were significantly improved, but there was no significant difference between the two groups, and the clearance rate of blood lactic acid in hypoxia group was higher than that in normoxic group, but there was no significant difference between the two groups, and the blood lactate clearance rate of hypoxia group was higher than that of normoxic group.The relative average power of hypoxia group was significantly higher than that of normoxic group, and there was no significant change in relative average power of normoxic group. There was no significant difference in relative average power between the two groups.Conclusion: repeated sprint training can improve the speed endurance of basketball players, and hypoxic repeated sprint training can effectively improve the lactate clearance ability of basketball players.
