竞技健美操运动员递增负荷下HRV的影响因素分析

Analysis on Factors Influencing the HRV under the Incremental Load for Aerobics Athletes

为了探讨递增负荷下竞技健美操运动员心率变异性,采用电子跑台递增负荷的测试方法,用芬兰心率遥测仪(polar RS800)远程遥测对运动员整个运动过程HRV时域、频域进行分析。让所有运动员以6m/s的起始速度,每分钟速度增加2m/s,测试时间6min。结果显示:1)以年龄分组比较显示LF,LF/HF(P<0.05)有差异性,其他变异指标都无差异性;以专业分组比较显示,HRp,SD2(P<0.01)差异性非常显著;SD1,LF(P<0.05)有差异性,其他变异指标无差异性;以心率分组比较中显示,HRp,SD1,SD2(P<0.01)差异性非常显著,其他变异指标都无差异性。2)男运动员之间比较显示,年龄分组所有HRV变异性指标都无差异性。在以专业分组的比较过程中显示,HRp,SD2,RMSSD(P<0.01)差异性非常显著,其他变异指标无差异性。在以心率分组的比较过程中显示,HRp,SD1,SD2(P<0.01)差异性非常显著,RMSSD(P<0.05)有差异性,其他变异指标无差异性。女运动员之间比较显示:HRp,SD2(P<0.01)差异性非常显著,其他变异指标无差异性。以心率分组的结果比较过程中显示,HRp,SD2(P<0.01)差异性非常显著,其他变异指标无差异性。以年龄分组的结果比较中显示,LF/HF(P<0.05)有差异性,其他变异指标无差异性。3)以专业分组比较显示:一级和健将级分组比较无统计学意义;二级分组比较显示,SD1,LF/HF(P<0.05)有差异性,其他变异指标无差异性。以心率分组的结果比较中显示,HRp(P<0.01)差异性非常显著;SD1,SD2,RMSSD(P<0.05)有差异性,其他变异指标无差异性。说明HRV指标可以作为一个监测运动效果的有效指标,并进一步为量化运动训练作出初步的尝试。

In order to explore heart rate variability of aerobics athletes under the incremental loas, using heart rate telemetry instrument of Finland （polar RSS00）, this paper analyzes the HRV time domain, fre- quency domain of the athletes throughout the course. Methods：All athletes start at 6m / s initial speed, increasing at rate of 2 m / s, whole test time 6 rain. The results showed that： （1）. Comparing the age group, there is difference between LF, LF / HF （P〈0. 05）,no differences in other indicators;comparing the professional group, there is significant differences in HRp, SD2 （P〈0. 01）;differences in SD1, LF （P 〈0. 05）, no differences in other indicators; comparing the heart rate group, there is significant differences in HRp, SD1, SD2 （P〈0. 01）, no differences in other indicators. （2）. Comparing the male and female ath-letes, there is no differences in age group of all HRV variability indicators. There is significant differences in HRp,SD2 ,RMSSD （P〈0. 01） of professional groups. Other mutations showed no differences. In a comparison of heart rate there is significant difference in HRp, SD1, SD2 （P〈0. 01）, difference in RMSSD （P〈0. 05）, other mutations showed no differences; comparing the female athletes： there is significant difference in HRp, SD2 （P〈 0. 01）. Other mutations showed no differences. Comparing the Heart rate groups, there is significant difference in HRp, SD2（P〈0. 01）. Other mutations showed no differences. Comparing the results of age groups, there differences in LF/HF （P〈0. 05）, other mutations showed no difference （3）. Comparing the professional groups： no statistical significance in group 1 and the athlete; two group comparison shows that there is no difference in SD1, LF / HF （P〈0. 05）. Other mutations showed no differences;comparing the heart rate group, there is significant difference in HRp （P〈0. 01） ; difference in SD1, SD2, RMSSD （P〈0. 05）, other mutations showed no differences. Results： HRV indicator can be used as an effective indicator for monitoring their effect and making an initial attempt for the further quantitative exercise.
