摘要
通过研究羽毛球运动员专项步法运动后心率与血乳酸浓度变化的相关性,可以准确地监控运动员的训练负荷。方法:以我国20名优秀青少年女子羽毛球运动员(单双打项目各10名)为研究对象,在羽毛球单打场地的半场四角分别放置5个羽毛球,让运动员以最快的速度依次推倒所有羽毛球,测定运动后1到5分钟内的心率(HR)和血乳酸(BLa)值。结果:在专项步法测试后的5分钟恢复期内,运动员的心率恢复和乳酸清除都具有明显的快速期(前2分钟)和慢速期(后3分钟)的区分,且单打运动员在快速恢复期内具有更好的心率恢复能力;专项步法测试后心率恢复率和血乳酸消除率与测试成绩具有显著的相关性,且单打运动员具有更强的乳酸生成和消除能力;心率恢复期和血乳酸恢复期之间没有显著相关性,但运动后的血乳酸峰值与5分钟内的心率恢复期呈负相关性(r=-0.72,P<0.01),其中血乳酸峰值与快速恢复期呈负相关(r=-0.65,P<0.01),但与慢速恢复期呈正相关关系(r=0.48,P<0.05)。结论:2分钟内的快速恢复期与局间间歇时间相同,且心率下降乳酸升高,可作为专项耐乳酸训练的间歇时间。恢复期内血乳酸峰值与不同心率恢复时间段具有不同的相关性,根据具体时间的相关性可以利用心率较准确的预测血乳酸峰值,更好地监控运动员的训练负荷。
By studying the correlation between the heart rate and blood lactate concentration after the special footwork of badminton athletes,the training load can be monitored more accurately.Methods:20 outstanding teenagers in China women's badminton players(singles&doubles each 10)as the research object,the four corners were placed in the badminton singles site half 5 badminton,badminton athletes at the fastest speed in turn down all,determination of 1 to 5 minutes after exercise heart rate(HR)and blood lactic acid(BLa)value.Results:1)during the 5-minute recovery period after the special footwork test,both the heart rate recovery and the lactic acid removal had obvious differences between the rapid period(the first 2 minutes)and the slow period(the last 3 minutes),and the singles athletes had better heart rate recovery ability during the rapid recovery period.2)the recovery rate of heart rate and the elimination rate of blood lactic acid have a significant correlation with the test results after the special footwork test,and the singles athletes have a stronger ability to generate and eliminate lactic acid.3)there was no significant correlation between heart rate convalescence and blood lactic acid convalescence,but the peak value of blood lactic acid after exercise was negatively correlated with the 5-minute heart rate convalescence(r=-0.72,P<0.01),which was negatively correlated with the rapid convalescence(r=-0.65,P<0.01),but positively correlated with the slow convalescence(r=0.48,P<0.05).Conclusion:the 2-minute period of rapid convalescence is the same as intersession interval time,during this period the heart rate drops and the lactic acid increases,can be used as the interval time of special anti-lactic acid training.The peak value of blood lactic acid has different correlation with the recovery period of different heart rates,so one index value cannot be used to predict another index value simply.
