Student-athletes face numerous challenges across their competitive season. Although mood states have been previously studied, little is known about adaptations in other psychological responses, specifically cognition. The purpose of this study was to characterize cognitive function, mood, sleep, and stress responses at select time points of a season in collegiate rowers. It was hypothesized that during baseline, typical training, and recovery, athletes would show positive mental health profiles, in contrast to decreases in cognition with increases in negative mood and measurements of stress during peak training.
Male and female Division I rowers (N = 43) and healthy controls (N = 23) were enrolled and assessed at baseline, typical training, peak training, and recovery. At each time point, measures of cognitive performance (Stroop color-naming task), academic and exercise load, perceived cognitive deficits, mood states, sleep, and stress (via self-report and salivary cortisol) were recorded.
Repeated-measures ANOVA revealed significant group-time interactions for perceived exercise load, cognitive deficits, mood states, and perceived stress (P < 0.05). For athletes during peak training, the perception of cognitive deficits was positively correlated with mood disturbance (r = 0.54, P < 0.05) and perceived stress (r = 0.55, P < 0.05) and negatively correlated with response accuracy during incongruent Stroop trials (r = -0.38, P < 0.05). Cognitive performance did not change over the course of the season for either group. Cortisol and sleepiness changed over the course of the season but no significant interactions were observed.
These results demonstrate that various psychological responses change over the course of a season, but they also highlight adaptation indicative of cognitive resilience among student-athletes.
学生运动员在整个竞技赛季面临众多挑战。虽然之前已经对情绪状态进行了研究,但对于其他心理反应,特别是认知方面的适应性了解甚少。本研究的目的是描述大学生赛艇运动员在赛季特定时间点的认知功能、情绪、睡眠和应激反应。研究假设,在基线、常规训练和恢复阶段,运动员将呈现积极的心理健康状况,而在高强度训练期间,随着负面情绪和应激指标的增加,认知能力会下降。
招募了男子和女子一级赛艇运动员(N = 43)和健康对照组(N = 23),并在基线、常规训练、高强度训练和恢复阶段进行评估。在每个时间点,记录认知表现(斯特鲁普颜色命名任务)、学业和运动负荷、感知到的认知缺陷、情绪状态、睡眠和应激(通过自我报告和唾液皮质醇)的测量数据。
重复测量方差分析显示,在感知运动负荷、认知缺陷、情绪状态和感知应激方面存在显著的组-时间交互作用(P < 0.05)。对于高强度训练期间的运动员,认知缺陷的感知与情绪障碍呈正相关(r = 0.54,P < 0.05),与感知应激呈正相关(r = 0.55,P < 0.05),与不一致斯特鲁普试验中的反应准确性呈负相关(r = -0.38,P < 0.05)。两组的认知表现在整个赛季中均未发生变化。皮质醇和嗜睡在整个赛季中发生了变化,但未观察到显著交互作用。
这些结果表明,各种心理反应在一个赛季的过程中会发生变化,但它们也突出了学生运动员认知恢复力的适应性表现。
