Using Heart Rate Variability Index to Monitor Yili Horse Warm-up Effect and Competition Performance
摘要
Abstract
[Objective] The study aims to explore the characteristics of HRV ( Heart Rate Variability) before competition in Yili horses and to provide theoretical basis for assessing the optimal state and competitive performance of Yili horses before competition.[Method]Seven Yili horses were selected and six test races were conducted. Indicators of the HRV were collected before and after the warm-up. The difference of each index before and after warm-up and its correlation with competition achievement were analyzed.[Result]The lowest R-R interval, average R-R interval, highest R-R interval, and PNN50 after the warm-up of Yili horse were highly lower than that before warm-up ( P＜0. 01) , and Lfnu was significantly lower than that be-fore warm-up ( P＜0. 05) ; VLF was highly higher than that before warm-up ( P＜0. 01) , TP was signifi-cantly higher than that before warm-up (P＜0. 05). The time domain indicators SDNN before warm-up, RMSSD and PNN50 were closely correlated with the competition results ( P＜0. 01) , and the frequency do-main indicators TP, Hfnu, LF, Lfnu, VLF, LF/HF were highly correlated with the competition results ( P＜0. 01) . The non-linear indicators SD1 and SD2 were highly associated with competition results ( P＜0. 01) . After the warm-up, the time domain indicators SDNN and RMSSD were significantly related to the perform-ance ( P＜0. 05) ; the frequency domain indicators TP and LF were significantly correlated with the competi-tion results ( P ＜0. 05) ; the nonlinear index SD1 was significantly related to the competition results ( P ＜0. 05).[Conclusion]The vagal nerve activity of horses before and after the warm-up of the 1,000 m test race is predominant , which is the main factor affecting the competitive state of the Yili horse. Therefore, the change in HRV index is an effective index to evaluate the competitive status of Yili horses, which can provide theoretical basis for the adjustment of best competitive state before the competition.关键词
