The current study examined differences in heart rate variability (HRV) across student-athletes of different eligibility classifications and analyzed differences in HRV when competing at home or away. Fourteen female collegiate volleyball players volunteered for the study. Data collection encompassed an entire collegiate season, with comparisons in HRV made between home and away games, as well as pre-gameday, gameday, and post-gameday recordings for the whole squad. Comparisons were also made between student-athlete eligibility classification, with self-reported measures of sleep quality, fatigue, muscle soreness, stress, and mood recorded at the time of HRV measurement. Freshman athletes reported a significantly (p < 0.05, η² = 0.17) lower HRV (80.3 ± 9.7) compared to sophomore (85.7 ± 7.2), junior (91.2 ± 8.3), and senior (86.5 ± 7.2) athletes, while junior athletes had a significantly higher HRV when compared to sophomore and senior athletes. All athlete classifications reported similar HRV for home and away games, and there was no difference in HRV for any athlete classification group when comparing pre-gameday, gameday, and post-gameday measures. Freshman athletes reported significantly (p < 0.05, η² = 0.23) worse mood states compared to the other eligibility classifications, while self-reported stress was significantly (p < 0.05) worse in junior and senior athletes. Results suggest that monitoring the workload of student-athletes based on their eligibility classification holds merit. Collegiate coaching and support staff should be aware of the academic and competitive demands placed on their student-athletes. In particular, freshman athletes adjusting to the increased demands placed on them as collegiate student-athlete may warrant additional support.

资格分类是了解学生运动员对大学排球比赛的反应的因素

当前的研究检查了不同资格类别的学生运动员之间心率变异性（HRV）的差异，并分析了在家中或外出比赛时心率变异性的差异。十四名女大学生排球运动员自愿参加了这项研究。数据收集涵盖整个大学赛季，对主场比赛和客场比赛之间的HRV进行比较，以及整个班级的赛前，赛后和赛后记录。还对学生-运动员资格分类进行了比较，并在HRV测量时记录了自我报告的睡眠质量，疲劳，肌肉酸痛，压力和情绪的测量值。大一运动员报告了显著（p <0.05，η ²= 0.17）与大二（85.7±7.2），初中（91.2±8.3）和高级（86.5±7.2）运动员相比，HRV（80.3±9.7）低，而初中与大二和高级运动员相比HRV显着更高。所有运动员分类报告的主场和客场比赛HRV相似，并且在比较赛前，赛后和赛后指标时，任何运动员分类组的HRV均无差异。大一运动员显著报道的（p <0.05，η ² = 0.23）更坏情绪状态相比于其他合格的分类，而自我报告的应力为显著（p<0.05）在初级和高级运动员中更糟。结果表明，根据学生的资格分类监控学生的工作量是值得的。大学教练和支持人员应了解对学生运动员的学术和竞争要求。特别是，新生作为适应大学学生运动员的要求不断提高的新生运动员，可能需要额外的支持。
