The current study used a complex, sport-specific movement skill to explore the effects of a win-shift/lose-stay practice schedule on learning and compared its effectiveness with that of blocked and random practice schedules. Thirty-six adults (24.9 ± 3.3 years) were assigned to blocked, random and learner-adapted training groups. Each participant performed 360 trials of the basketball set shot from multiple locations across six practice sessions. For the learner-adapted group, switching between task variations was performance-contingent; switching between shooting locations occurred only following a successful shot. Shooting success was calculated as the percentage of successful shots performed, and measured during pre-acquisition (i.e. baseline), acquisition (i.e. practice) and post-acquisition (i.e. retention and transfer). Despite scoring less shots throughout practice compared to baseline testing, the learner-adapted group showed a significant improvement for shooting success in transfer ( = 1.02). Blocked practice demonstrated significant improvements for shooting success in immediate retention ( = 1.83), delayed retention ( = 1.69) and transfer ( = 1.39). Random practice significantly improved shooting success in both immediate ( = 1.03) and delayed retention ( = 0.81). The current findings highlight that performance during practice does not necessarily represent the permanency and adaptability of skill learning. The implications of the findings and their practical applications are discussed in the context of practice scheduling during learning of a sports skill.
本研究使用了一种复杂的、特定于运动的动作技能,来探索赢变/输不变的练习安排对学习的影响,并将其与分组和随机练习安排的效果进行比较。36 名成年人(24.9 ± 3.3 岁)被分配到分组、随机和学习者适应训练组。每个参与者在六个练习阶段从多个位置完成 360 次篮球定点投篮。对于学习者适应组,任务变化之间的切换是基于表现的;只有在成功投篮后才会在投篮位置之间切换。投篮成功率的计算方法是成功投篮的百分比,并在预获取(即基线)、获取(即练习)和后获取(即保留和转移)期间进行测量。尽管在练习过程中的投篮次数比基线测试少,但学习者适应组在转移测试中的投篮成功率有显著提高( = 1.02)。分组练习在即时保留( = 1.83)、延迟保留( = 1.69)和转移( = 1.39)方面显著提高了投篮成功率。随机练习在即时( = 1.03)和延迟保留( = 0.81)方面都显著提高了投篮成功率。目前的研究结果表明,练习过程中的表现并不一定代表技能学习的永久性和适应性。在运动技能学习过程中,讨论了这些发现的意义及其在练习安排方面的实际应用。
