睡眠已被认为是实现最佳性能所必需的最重要的恢复方法之一。然而,仍然缺乏科学文献来研究其对篮球比赛中最普遍的技能之一的影响,反运动垂直跳跃(CVJ)。因此,本研究的目的是研究睡眠质量和数量之间的关系,和一组半职业男子篮球运动员的下半身神经肌肉表现特征。28名参加塞尔维亚一级地区联赛的运动员自愿参加了这项调查。一到达健身房,所有运动员均完成匹兹堡睡眠质量指数(PSQI)自测问卷.PSQI完成后,每名运动员踩下力板系统,并进行了3次无手臂摆动的最大努力CVJ。获得以下力-时间指标进行分析:偏心和同心绝对和相对平均值以及峰值力和功率,垂直跳跃高度,和反应强度指数改性。皮尔逊积矩相关系数用于检查睡眠质量和数量与下体神经肌肉性能特征之间的线性关系的强度(p<0.05)。结果表明,睡眠质量似乎对CVJ的同心比偏心阶段有更大的影响(例如,同心平均力[r=-0.830;p<0.001],相对同心峰值力[r=-0.466;p=0.013,偏心平均功率(r=-0.162;p=0.409)],而睡眠量与下体神经肌肉表现之间没有显著关系(例如,同心峰值力[r=-0.055;p=0.782],相对偏心平均功率[r=-0.301;p=0.107])。总的来说,这些发现为良好睡眠卫生的重要性提供了有价值的见解(例如,效率,持续时间)在运动人群中,并可以帮助从业者制定更有效的培训和恢复计划。
Sleep has been recognized as one of the most essential recovery methods necessary for achieving optimal performance. However, there is still a lack of scientific literature focused on examining its impact on one of the most prevalent skills in the game of basketball, the countermovement vertical jump (CVJ). Therefore, the purpose of the present study was to examine the relationship between sleep quality and quantity, and lower-body neuromuscular performance characteristics within a cohort of semi-professional male basketball players. Twenty-eight athletes competing in a first-tier regional league in Serbia volunteered to participate in this investigation. Upon arrival at the gym, all athletes completed the Pittsburgh Sleep Quality Index (PSQI) self-rated questionnaire. Immediately after completion of the PSQI, each athlete stepped on a force plate system and performed three maximum-effort CVJs with no arm swing. The following force-time metrics were obtained for the analysis:
eccentric and concentric absolute and relative mean and peak force and power, vertical jump height, and reactive strength index-modified. Pearson product-moment correlation coefficients were used to examine the strength of the linear relationships between sleep quality and quantity and lower-body neuromuscular performance characteristics (p < 0.05). The results indicated that sleep quality appears to have a greater impact on the concentric than the
eccentric phase of the CVJ (e.g., concentric mean force [r = -0.830; p < 0.001], relative concentric peak force [r = -0.466; p = 0.013,
eccentric mean power (r = -0.162; p = 0.409)], while no significant relationship was found between sleep quantity and lower-body neuromuscular performance (e.g., concentric peak force [r = -0.055; p = 0.782], relative
eccentric mean power [r = -0.301; p = 0.107]). Overall, these findings offer valuable insights into the importance of good sleep hygiene (e.g., efficiency, duration) in an athletic population, and can help practitioners develop more effective training and recovery programs.
