| 摘 要： | 【目的】研究伊犁马赛前HRV(心率变异性)的特点,为评估伊犁马赛前状态及竞技表现提供理论依据。【方法】选取伊犁马7匹,测试赛共6场,采集HRV热身前及热身后数值,分析热身前、后各指标差异性及其与竞赛成绩相关性。【结果】伊犁马热身后最低R-R间距、平均R-R间距、最高R-R间距、PNN50极显著低于热身前(P＜0.01),Lfnu显著低于热身前(P＜0.05);VLF极显著高于热身前(P＜0.01),TP显著高于热身前(P＜0.05)。热身前时域指标SDNN、RMSSD、PNN50与竞赛成绩极显著相关(P＜0.01);频域指标TP、Hfnu、LF、Lfnu、VLF、LF/HF与竞赛成绩极显著相关(P＜0.01);非线性指标SD1、SD2与竞赛成绩极显著相关(P＜0.01)。热身后时域指标SDNN、RMSSD与竞赛成绩显著相关(P＜0.05);频域指标TP、LF与竞赛成绩显著相关(P＜0.05);非线性指标SD1与竞赛成绩显著相关(P＜0.05)。【结论】马匹1 000 m测试赛热身前、后迷走神经活性占主导地位,是影响伊犁马竞技状态的主要因素。通过HRV变化能有效监控伊犁马热身效果及竞赛表现。

| 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 before warm-up (P<0.05); VLF was highly higher than that before warm-up (P<0.01), TP was significantly 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 domain 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 performance (P<0.05); the frequency domain indicators TP and LF were significantly correlated with the competition 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. |
