PURPOSE
To compare heart rate variability (HRV) in healthy male and female athletes with versus without a history of concussion.
METHODS
A cross-sectional study of 113 healthy interuniversity athletes (n = 62 female; n = 51 male) across nine sports from a single institution, participating within the first half of their respective athletic seasons. Concussion history was determined by self-report (males: yes = 20, no = 31; females: yes = 21, no = 41). HRV was measured over five-minute time intervals in both seated and supine positions. All analyses were adjusted for age.
RESULTS
No differences in HRV were observed in female athletes with versus without a history of concussion; male athletes with a history of concussion displayed a significantly lower mean RR in the seated position compared to athletes with no history of concussion.
CONCLUSION
In the months-to-years following a concussion, HRV does not appear to be significantly perturbed. However, males with a history of concussion may have a slightly lower mean RR. Future studies evaluating HRV and concussion history should be mindful of the confounding influence of sex and age.
目的
比较有和无脑震荡史的健康男性和女性运动员的心率变异性（HRV）。
方法
这是一项单中心的横断研究，共纳入了来自 9 项运动的 113 名健康大学生运动员（女性 62 名，男性 51 名），他们均处于运动赛季的前半段。通过自我报告来确定脑震荡史（男性：有 20 名，无 31 名；女性：有 21 名，无 41 名）。在坐姿和仰卧位下，通过 5 分钟的时间间隔来测量 HRV。所有分析均根据年龄进行了调整。
结果
有和无脑震荡史的女性运动员之间的 HRV 没有差异；与无脑震荡史的运动员相比，有脑震荡史的男性运动员在坐姿下的平均 RR 明显较低。
结论
在脑震荡后的数月至数年内，HRV 似乎没有明显受到干扰。然而，有脑震荡史的男性的平均 RR 可能略低。未来评估 HRV 和脑震荡史的研究应注意性别和年龄的混杂影响。
