The purpose of this study was to assess the effect of a soccer match on the cardiac autonomic control of heart rate (HR) in soccer referees. Sixteen Spanish regional and third division referees (11 males: 26 ± 7 years, 74.4 ± 4.1 kg, 178 ± 3 cm, Yo-Yo IR1 ~600-1,560 m; 5 females: 22 ± 3 years, 59.3 ± 4.8 kg, 158 ± 8 cm, Yo-Yo IR1 ~200-520 m) participated with 24-h HR recordings measured with a Polar RS800 during a rest and a match day. Autonomic control of HR was assessed from HR variability (HRV) analysis. Inclusion of a soccer match (92.5% spent at >75% maximum HR) reduced pre-match (12:00-17:00 hours; small to moderate), post-match (19:00-00:00 hours; moderate to almost perfect), and night-time (00:00-05:00 hours; small to moderate) HRV. Various moderate-to-large correlations were detected between resting HRV and the rest-to-match day difference in HRV. The rest-to-match day differences of low and high-frequency bands ratio (LF/HF) and HR in the post-match period were moderately correlated with time spent at different exercise intensities. Yo-Yo IR1 performance was highly correlated with jump capacity and peak lactate, but not with any HRV parameter. These results suggest that a greater resting HRV may allow referees to tolerate stresses during a match day with referees who spent more time at higher intensities during matches exhibiting a greater LF/HF increment in the post-match period. The relationship between match activities, [Formula: see text] and HR recovery kinetics in referees and team sport athletes of different competitive levels remains to be clarified.
本研究旨在评估一场足球比赛对足球裁判心率（HR）心脏自主控制的影响。16 名西班牙地区和第三级别裁判（11 名男性：26 ± 7 岁，74.4 ± 4.1kg，178 ± 3cm，Yo-YoIR1 约 600-1560m；5 名女性：22 ± 3 岁，59.3 ± 4.8kg，158 ± 8cm，Yo-YoIR1 约 200-520m）参与了研究，他们在比赛日和休息日使用 Polar RS800 进行了 24 小时 HR 记录。HR 变异性（HRV）分析用于评估 HR 的自主控制。足球比赛的纳入（92.5%的时间花在>75%最大 HR 上）降低了赛前（12:00-17:00 小时；小到中等）、赛后（19:00-00:00 小时；中等至接近完美）和夜间（00:00-05:00 小时；小到中等）的 HRV。在静息 HRV 与 HRV 休息至比赛日的差异之间检测到各种中等至大的相关性。比赛后期间，LF/HF 比值和 HR 的低和高频带差值与不同运动强度下的时间呈中度相关。Yo-YoIR1 表现与跳跃能力和峰值乳酸高度相关，但与任何 HRV 参数无关。这些结果表明，更大的静息 HRV 可能使裁判在比赛日中承受压力，而在比赛中花费更多时间处于较高强度的裁判在赛后期间表现出更大的 LF/HF 增加。不同竞技水平的裁判和团队运动运动员之间的比赛活动、[Formula: see text]与 HR 恢复动力学之间的关系仍有待澄清。
