The relationship between heart rate variability (HRV) and training load in team-sport is unknown. We therefore assessed relations between completed training-load in the previous 1-, 3- and 7-days and waking HRV in professional Australian Rules Football. Linear-mixed models analysed changes in HRV, considering training load from the previous 1-, 3- and 7-days. Total Distance (TD), distance >14.4 km ‧ h-1 (HSR) and >24.9 km ‧ h-1 (Sprint-Distance), duration >85% max heart rate and Rating of Perceived Exertion were included as independent variables. Sub-group analysis of season-phase and years of professional experience was also conducted. Increased three-day Sprint-Distance reduced HRV in the first 8-weeks of pre-season (-13.1 ms, p = 0.03) and across the data collection period (-3.75 ms, p = 0.01). In first-year players, higher previous-day (-63.3 ms, p=0.04) and seven-day TD (-38.2 ms, p = 0.02) reduced HRV, whilst higher seven-day HSR increased HRV (34.5 ms, p = 0.01). In players with five-to-seven years of professional experience, higher three-day (-14.4 ms, p = 0.02) and seven-day TD (-15.7 ms, p = 0.01) reduced HRV, while higher three-day HSR increased HRV (12.5 ms, p = 0.04). In players with greater than eight years of professional experience, higher previous-day Sprint-Distance reduced HRV (-13.1 ms, p < 0.008). Completed training load across the previous 7-days influences HRV, but the relation between variables is complex and influenced by professional experience and season-phase.
在团队运动中，心率变异性（HRV）与训练负荷之间的关系尚不清楚。因此，我们评估了过去 1 天、3 天和 7 天的完成训练负荷与专业澳式足球运动员的静息 HRV 之间的关系。线性混合模型分析了 HRV 的变化，考虑了过去 1 天、3 天和 7 天的训练负荷。总距离（TD）、>14.4km/h（HSR）和>24.9km/h（Sprint-Distance）距离、>85%最大心率持续时间和感知运动强度被视为独立变量。还进行了赛季阶段和专业经验年限的亚组分析。在季前赛的前 8 周（-13.1ms，p=0.03）和整个数据采集期间（-3.75ms，p=0.01），三天 Sprint-Distance 的增加降低了 HRV。在第一年的球员中，前一天（-63.3ms，p=0.04）和七天 TD（-38.2ms，p=0.02）较高会降低 HRV，而七天 HSR 较高会增加 HRV（34.5ms，p=0.01）。在有 5-7 年专业经验的球员中，三天（-14.4ms，p=0.02）和七天 TD（-15.7ms，p=0.01）较高会降低 HRV，而三天 HSR 较高会增加 HRV（12.5ms，p=0.04）。在有 8 年以上专业经验的球员中，前一天 Sprint-Distance 的增加会降低 HRV（-13.1ms，p<0.008）。过去 7 天的完成训练负荷会影响 HRV，但变量之间的关系很复杂，受专业经验和赛季阶段的影响。
