: Volleyball demands high levels of anaerobic strength, flexibility, agility, and mental focus. Adequate sleep has been shown to enhance athletic performance and cognitive function. This study investigates the impact of post-lunch naps of varying durations (25 and 45 min) on the physiological performance and cognitive focus of elite volleyball players. : Sixteen elite volleyball players (8 male, 8 female) with at least 7 years of competitive experience participated in a randomized crossover study. They underwent three experimental conditions: no nap (No-Nap), a 25-min nap (N25), and a 45-min nap (N45). Physical performance was measured through counter-movement jumps (CMJ) and volleyball agility tests, while cognitive function was assessed using the D2 attention test. Statistical analysis included repeated measures ANOVA to examine the differences between nap conditions and gender-specific responses. : Significant improvements in both physical performance and cognitive focus were observed in the N25 and N45 conditions compared to the No-Nap condition (indicating the effectiveness of short naps in enhancing both physical and mental performance). Males outperformed females in most physical metrics, while females scored higher on the D2 attention test (suggesting possible gender-specific responses to napping). The 25-min nap showed slightly better results in terms of sleep quality and subsequent performance (confirming that shorter naps may be more beneficial). : Post-lunch naps, especially of 25 or 45 min, enhance both physiological and cognitive performance in elite volleyball players. These findings suggest that integrating short naps into athletes' training regimens can improve performance and focus, with potential gender-specific benefits. Further research is needed to explore long-term effects and variations across other sports.
: 排球需要高水平的无氧力量、灵活性、敏捷性和精神集中力。充足的睡眠已被证明可以提高运动表现和认知功能。本研究调查了不同时长（25 分钟和 45 分钟）午饭后小睡对精英排球运动员生理表现和认知集中力的影响。 : 16 名具有至少 7 年竞技经验的精英排球运动员（8 名男性，8 名女性）参加了一项随机交叉研究。他们经历了三种实验条件：无小睡（No-Nap）、25 分钟小睡（N25）和 45 分钟小睡（N45）。通过反跳式跳跃（CMJ）和排球敏捷测试测量身体表现，而使用 D2 注意力测试评估认知功能。统计分析包括重复测量方差分析，以检查小睡条件之间的差异和性别特异性反应。 : 与 No-Nap 条件相比，N25 和 N45 条件下的身体表现和认知集中力都有显著提高（表明短时间小睡可以提高身体和心理表现）。在大多数身体指标上，男性表现优于女性，而女性在 D2 注意力测试中得分更高（表明可能存在性别特异性的小睡反应）。25 分钟小睡在睡眠质量和随后的表现方面显示出稍好的结果（证实较短的小睡可能更有益）。 : 午饭后小睡，尤其是 25 分钟或 45 分钟的小睡，可以提高精英排球运动员的生理和认知表现。这些发现表明，将短暂小睡纳入运动员的训练方案可以提高表现和注意力，可能具有性别特异性的益处。需要进一步研究来探索长期影响和不同运动的变化。
