Abstract

: Orienteering is a sport characterized by high physical exertion and intense mental demands, which increase susceptibility to errors. Understanding the impact of such errors on psychophysiological responses, particularly on heart rate variability (HRV), is essential. This study aimed to investigate the relationship between psychophysiological indicators and checkpoint errors made by elite orienteers during official competition. : Fifty-three orienteers participated in this study, and their performance was continuously monitored and recorded by using a global positioning system (GPS) and HRV data. Errors made during the orienteering events were identified and analyzed. HRV data were examined in three temporal segments: before, during, and after the identified and standardized errors. : The analyses indicated that errors significantly impacted HRV indices across multiple domains: the time domain, frequency domain, and nonlinear domain. Additionally, a significant effect of sex on the normalized the root mean square of successive differences (r-MSSD) before and after the error was observed. : The findings of this study underscore the significant impact of errors made by orienteers on cardiovascular responses, as evidenced by measurable alterations in HRV metrics. Cardiovascular activity, represented by the HRV, can provide useful information for coaches and sport psychologists to adopt effective training programs for athletes.

摘要

定向运动是一项以高强度身体活动和精神需求为特点的运动,这增加了出错的可能性。了解此类错误对心理生理反应的影响,特别是对心率变异性(HRV)的影响,至关重要。本研究旨在调查精英定向运动员在正式比赛中出现的心理生理指标与检查点错误之间的关系。

本研究共有 53 名定向运动员参与,使用全球定位系统(GPS)和 HRV 数据对他们的表现进行连续监测和记录。识别并分析定向比赛中的错误。对 HRV 数据进行了三个时间片段的检查:在识别和标准化错误之前、期间和之后。

分析表明,错误对多个领域的 HRV 指数产生了显著影响:时域、频域和非线性域。此外,还观察到性别对错误前后归一化均方根差的连续差异(r-MSSD)有显著影响。

本研究的结果强调了定向运动员犯错误对心血管反应的重大影响,这可以通过 HRV 指标的可测量变化来证明。以 HRV 为代表的心血管活动可以为教练和运动心理学家提供有用的信息,以便为运动员制定有效的训练计划。
