Sleep has long been shown as important for memory processing and retention, and has recently been implicated in motor memory consolidation. However, it is not known whether sports skills, including basketball shooting skills, are also affected by sleep in young, healthy individuals. Therefore, we investigated whether sleep before and after basketball shooting skill training affected the acquisition and retention of shooting skills. This study included 19 healthy male subjects who participated in a basketball shooting skill training session (100 shots) and a retention test performed 2 days later (30 shots). The learning and retention indices were calculated using performance scores that evaluated each subject's shooting skills. A wearable activity tracker was used to measure sleep parameters for 4 consecutive days, 2 days before and 2 days after training. We discovered the relationship between sleep duration before and after training and retention of shooting skills (sleep duration before training; p = 0.044, r = 0.467, sleep duration after training; p = 0.006, r = 0.606). The retention index for the subgroup with long sleep duration before and after training was significantly higher than that for the subgroup with short sleep duration before and after training, respectively (p = 0.021 for both). There was no significant relationship between learning index and each sleep parameter. Our results demonstrated that sleep duration before and after training was related to retention of shooting skills following basketball shooting skills training.
长期以来，睡眠对记忆处理和记忆保持都很重要，最近还被认为与运动记忆巩固有关。然而，在年轻健康个体中，包括篮球投篮技能在内的运动技能是否也会受到睡眠的影响尚不清楚。因此，我们研究了篮球投篮技能训练前后的睡眠是否会影响投篮技能的习得和保持。本研究纳入了19名健康男性受试者，他们参加了一次篮球投篮技能训练课程（100次投篮），并在两天后进行了一次保持测试（30次投篮）。学习和保持指标是使用评估每个受试者投篮技能的表现分数来计算的。使用可穿戴活动追踪器连续4天测量睡眠参数，训练前2天和训练后2天。我们发现训练前后的睡眠时间与投篮技能的保持之间存在关联（训练前睡眠时间；p = 0.044，r = 0.467，训练后睡眠时间；p = 0.006，r = 0.606）。训练前后睡眠时间长的亚组的保持指标分别显著高于训练前后睡眠时间短的亚组（两者均为p = 0.021）。学习指标与各睡眠参数之间无显著关联。我们的结果表明，篮球投篮技能训练前后的睡眠时间与投篮技能训练后的保持有关。
