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.

脑震荡的历史与运动员对心率变异性的最小扰动有关。

目的

比较有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

对来自同一机构的九项运动中的113名健康的大学运动员进行的横断面研究（n = 62女； n = 51男），参加了各自运动季节的上半年。脑震荡史由自我报告决定（男性：是= 20，否= 31；女性：是= 21，否= 41）。在坐姿和仰卧姿势下，每隔五分钟测量一次HRV。所有分析均根据年龄进行了调整。

结果

有或没有脑震荡史的女运动员的HRV没有差异。与没有脑震荡史的运动员相比，有脑震荡史的男性运动员的坐姿平均RR明显较低。

结论

在脑震荡后的几个月至几年中，HRV似乎并未受到明显干扰。但是，有脑震荡史的男性平均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。
