在睡眠不足的情况下，早晨进行高强度运动（HIE）可能会损害与充足睡眠和HIE相关的健康益处。因此，本研究的目的是通过监测心率变异性（HRV）指数，探讨急性部分睡眠剥夺对HIE表现和心脏自主神经活动的影响。招募29名健康的大学男性青少年，在正常对照睡眠（对照组）≥7小时和急性部分睡眠剥夺(SD)≤4小时后，在跑步机上进行一次性HIE治疗（布鲁斯方案）。在对照期和SD期开始时以及在两种睡眠条件下运动后，心率（HR）、正态与正态标准差（SDNN）、连续神经网络间隔均方差的平方根（RMSSD）、归一化低频功率（LFn）、归一化高频功率（HFn）、整个记录计数中相差≥50 ms的相邻神经网络间隔数除以所有神经网络间隔总数（pNN50）。在直立坐姿休息时测量poincar<s:1>地块（SD1和SD2）的短轴和长轴值。在对照组和SD期，参与者的睡眠时间分别为7.63±0.52和3.78±0.69小时（p < 0.001）。与对照组相比，睡眠剥夺组的运动时间、RMSSD、HFn、SD1和pNN50显著减少，运动时最大心率显著增加（p < 0.05）。运动后SDNN、RMSSD、HFn、SD1、pNN50显著降低（p分别< 0.05、0.01、0.001）。总之，急性部分睡眠剥夺影响第二天早上的有氧运动表现，导致心脏迷走神经活动下降和心脏自主神经功能障碍。
Performing high-intensity exercise (HIE) in the morning under sleep deprivation may harm the health benefits related to sufficient sleep and HIE. Therefore, the aim of this study was to explore the effects of acute-partial sleep deprivation on HIE performance and cardiac autonomic activity by monitoring heart rate variability (HRV) indices. Twenty-nine healthy male adolescents in college were recruited to perform a one-time HIE session on the treadmill (Bruce protocol) after ≥7 h of normal control sleep (control) and after ≤4 h of acute-partial sleep deprivation (SD). At the beginning of control and SD periods and after exercising under the two sleep conditions, heart rate (HR), standard deviation of normal to normal (SDNN), square root of the mean squared differences of successive NN intervals (RMSSD), normalized low frequency power (LFn), normalized high frequency power (HFn), number of pairs adjacent NN intervals differing by ≥50 ms in the entire recording count divided by the total number of all NN intervals (pNN50), and short axis and long axis value in Poincaré plot (SD1 and SD2) were measured at rest in an upright sitting position. The participants slept 7.63 ± 0.52 and 3.78 ± 0.69 h during control and SD periods, respectively (p < 0.001). Compared with the control participants, those suffering sleep deprivation experienced a significant decrease in exercise duration, RMSSD, HFn, SD1, and pNN50 as well as a significant increase in maximum heart rate during exercise (p < 0.05). SDNN, RMSSD, HFn, SD1, and pNN50 decreased significantly after exercise (p < 0.05 and 0.01 and 0.001, respectively). In summary, acute-partial sleep deprivation affected aerobic exercise performance the next morning and led to decreased cardiac vagus activity and cardiac autonomic dysfunction.
