Heart Rate Variability (HRV) has been typically used to monitor athletes' physical fitness readiness. The supine position maximizes parasympathetic tone, which is important for monitoring in continuous aerobic sports, however, this is not the case of team sports that rely on anaerobic intermittent bouts, thus increasing sympathetic activation and vagal withdrawal. We hypothesized that HRV during sympathetic activation and vagal withdrawal would be a useful marker to evaluate perceived physical fitness in team sports. HRV was measured in both supine and standing positions during the mornings of 4 match days in 14 professional players. The supine Root Mean Square of the Successive Differences (RMSSD), as well as spectral analysis indices were recorded. Perceived physical fitness was assessed after each match by means of a visual analogue scale (VAS). Supine RMSSD was moderately correlated with perceived physical fitness (rho = 0.416), however, larger correlations were observed for supine and standing spectral indices (rho > 0.5). Correlation between RMSSD and Total Power was very large, thus questioning the usual interpretation of RMSSD (rho > 0.7). Standing Spectral HRV analyses may be a useful method for evaluating perceived physical fitness in the context of team sports. RMSSD may reflect the overall variability of HR and not only the parasympathetic influence, as observed in the current study.
心率变异性（HRV）通常用于监测运动员的身体适应能力。仰卧位可使副交感神经张力最大化，这对于持续有氧运动的监测很重要，然而，对于依赖无氧间歇运动的团队运动来说并非如此，因此会增加交感神经激活和迷走神经撤离。我们假设，在交感神经激活和迷走神经撤离期间的HRV将是评估团队运动中身体适应能力的一个有用指标。在14名职业球员4个比赛日的早晨，分别在仰卧位和站立位测量了HRV。记录了仰卧位的逐次差值均方根（RMSSD）以及频谱分析指标。每场比赛后通过视觉模拟量表（VAS）评估身体适应能力。仰卧位RMSSD与身体适应能力呈中度相关（rho = 0.416），然而，仰卧位和站立位的频谱指标相关性更大（rho > 0.5）。RMSSD与总功率之间的相关性非常大，因此对RMSSD的通常解释提出了质疑（rho > 0.7）。站立位频谱HRV分析可能是评估团队运动中身体适应能力的一种有用方法。如本研究中所观察到的，RMSSD可能反映了心率的总体变异性，而不仅仅是副交感神经的影响。
