Abstract

PURPOSE

To examine whether the interaction between exercise intensity and sleep duration/quality is associated with heart rate variability (HRV).

METHODS

A sample of 391 adults (M = 57 years) from the Midlife in the United States Biomarker study 2004-2009 provided sleep actigraphy, electrocardiogram (ECG) HRV measurements, completed the Pittsburgh Sleep Quality Index (PSQI), and answered questions on exercise habits. Participants were grouped as short (< 6 h) or non-short sleepers (≥ 6 h), poor (> 5 PSQI global score), or good sleepers (< 6 PSQI global score), and exercise was divided into vigorous (VPA) and moderate (MPA) intensities. Based on CDC guidelines, VPA was classified into adequate (≥ 75 min/week) and inadequate (< 75 min/week) groups. For MPA, adequate (≥ 150 min/week) and inadequate (< 150 min/week) groups. Linear models, adjusted for sociodemographic and health-related covariates, examined the interaction between sleep duration/quality and exercise on HRV.

RESULTS

Inadequate VPA was associated with lower HRV, HF-HRV (B = - 0.25, SE = 0.09, p = 0.007), and RMSSD (B = - 0.15, SE = 0.05, p = 0.0009). MPA showed no significant main associations with HRV. Sleep duration/quality did not show direct associations with HRV; however, interactions were found with sleep duration. Among short sleepers, inadequate VPA was associated with lower HF-HRV (B = - 0.62, SE = 0.25, p = 0.01) and inadequate MPA was associated with lower RMSSD (B = - 0.26, SE = 0.10, p = 0.01) compared to adequate exercise. Among non-short sleepers, there were no significant differences in HRV between exercise groups.

CONCLUSION

These findings suggest that short sleep and inadequate exercise may interact to lower HRV.

摘要

目的

研究运动强度与睡眠时间/质量之间的相互作用是否与心率变异性（HRV）相关。

方法

从2004 - 2009年美国中年生物标志物研究中选取391名成年人（平均年龄57岁）作为样本，他们提供了睡眠活动记录仪数据、心电图（ECG）HRV测量值，完成了匹兹堡睡眠质量指数（PSQI），并回答了有关运动习惯的问题。参与者被分为短睡眠者（<6小时）或非短睡眠者（≥6小时）、睡眠质量差（PSQI全球评分>5）或睡眠质量好（PSQI全球评分<6），运动分为剧烈运动（VPA）和中等强度运动（MPA）。根据美国疾病控制与预防中心（CDC）的指南，VPA分为充足组（≥75分钟/周）和不足组（<75分钟/周）。对于MPA，分为充足组（≥150分钟/周）和不足组（<150分钟/周）。采用线性模型，并对社会人口统计学和健康相关协变量进行调整，以研究睡眠时间/质量与运动对HRV的相互作用。

结果

VPA不足与较低的HRV、高频HRV（B = -0.25，标准误 = 0.09，p = 0.007）和RMSSD（B = -0.15，标准误 = 0.05，p = 0.0009）相关。MPA与HRV无显著的主要关联。睡眠时间/质量与HRV无直接关联；然而，发现与睡眠时间存在相互作用。在短睡眠者中，与充足运动相比，VPA不足与较低的高频HRV（B = -0.62，标准误 = 0.25，p = 0.01）相关，MPA不足与较低的RMSSD（B = -0.26，标准误 = 0.10，p = 0.01）相关。在非短睡眠者中，运动组之间的HRV无显著差异。
