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 ( < 0.05, η = 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 ( < 0.05, η = 0.23) worse mood states compared to the other eligibility classifications, while self-reported stress was significantly ( < 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.
本研究调查了不同资格分类的学生运动员在心率变异性（HRV）方面的差异，并分析了在主场或客场比赛时HRV的差异。14名大学女子排球运动员自愿参与了该研究。数据收集涵盖了整个大学赛季，比较了主场和客场比赛的HRV，以及全队在赛前、比赛日和赛后的记录。还比较了学生运动员的资格分类，并在测量HRV时记录了自我报告的睡眠质量、疲劳、肌肉酸痛、压力和情绪指标。与大二（85.7±7.2）、大三（91.2±8.3）和大四（86.5±7.2）运动员相比，大一运动员的HRV显著更低（<0.05，η=0.17）（80.3±9.7），而大三运动员与大二和大四运动员相比，HRV显著更高。所有运动员分类在主场和客场比赛中的HRV相似，在比较赛前、比赛日和赛后测量时，任何运动员分类组的HRV均无差异。与其他资格分类相比，大一运动员报告的情绪状态显著更差（<0.05，η=0.23），而大三和大四运动员自我报告的压力显著更差（<0.05）。结果表明，根据学生运动员的资格分类来监测其工作量是有价值的。大学教练和支持人员应意识到对其学生运动员的学业和比赛要求。特别是，刚进入大学的大一运动员在适应作为大学生运动员增加的要求时，可能需要额外的支持。
