基于HRV指标变化监测昆明犬的运动效果及工作表现
|
摘要
旨在研究昆明犬运动前后心率变异性(HRV)的特点,为评估昆明犬在运动状态下的工作表现及效果提供理论依据。选取8头搜索类专业训成昆明犬,在跑步机上以6 km/h的时速运动10 min,分别采集运动前、后的HRV值,分析运动前后各指标差异及其与工作成绩的相关性。结果显示,运动后SDNN(R-R间距标准差)和RMSSD(相邻R-R间距之差的均方根值)指标与运动前差异显著,平均R-R间距与工作成绩显著相关;运动后时域指标SDNN、RMSSD和平均R-R间距与工作成绩显著相关,其中平均R-R间距与工作成绩显著负相关;非线性指标SD1(全部正常2个R波的标准差Y)和SD2(全部正常2个R波的标准差X)与工作成绩显著相关;运动后最低R-R间距、平均R-R间距、最高R-R间距和PNN50极显著低于运动前;运动前、后迷走神经指标SDNN、RMSSD、SD1等与工作成绩极显著相关;运动后非线性指标SD1、SD2比运动前略微上升,但差异不显著。表明昆明犬运动前、后迷走神经活性占主导地位,是影响工作犬工作状态的主要因素。
The purpose of this study is to investigate the characteristics of HRV(Heart rate vail-rability) of Kunming Canine before and after exercise, and to provide a theoretical basis for evaluating the performance and effect of Kunming Canine in sports.Eight professional search canines were selected to be trained as Kunming Canine, and they were exercised on a treadmill at a speed of 6 km per hour for 10 minutes.The pre-exercise and post-exercise values of HRV were collected, and the differences of indicators before and after exercise and their correlation with work performance were analyzed.The results showed that the indicators of SDNN(standard deviation of RR spacing) and RMSSD(root mean square of the difference between adjacent RR spacing) were significantly different from those before exercise, and the average RR spacing was significantly correlated with the results; the time domain indicators after exercise were SDNN, RMSSD.The average RR interval was significantly correlated with the score, and the average RR interval had significantly negative correlation with the score; Nonlinear indices SD1(standard deviation Y of all normal 2 R waves) and SD2(all normal 2 R wave standard deviations X) were significantly correlated with scores; the lowest RR interval after exercise, the average RR interval, the highest RR interval, PNN50 were significantly lower than before exercise; the indicators of SDN, RMSSD, SD1 in vagus nerve before and after exercise were significantly correlated with the score; compared with performance before exercise, nonlinear index SD1, SD2 increased slightly after the exercise, but there was no significant change.In conclusion, the vagal activity of Kunming Canine before and after exercise is dominant, which is the main factor affecting the performance of working Canine.
