Cross-sectional evidence has demonstrated the importance of motor skill proficiency to physical activity participation, but it is unknown whether skill proficiency predicts subsequent physical activity.
In 2000, children's proficiency in object control (kick, catch, throw) and locomotor (hop, side gallop, vertical jump) skills were assessed in a school intervention. In 2006/07, the physical activity of former participants was assessed using the Australian Physical Activity Recall Questionnaire. Linear regressions examined relationships between the reported time adolescents spent participating in moderate-to-vigorous or organized physical activity and their childhood skill proficiency, controlling for gender and school grade. A logistic regression examined the probability of participating in vigorous activity.
Of 481 original participants located, 297 (62%) consented and 276 (57%) were surveyed. All were in secondary school with females comprising 52% (144). Adolescent time in moderate-to-vigorous and organized activity was positively associated with childhood object control proficiency. Respective models accounted for 12.7% (p = .001), and 18.2% of the variation (p = .003). Object control proficient children became adolescents with a 10% to 20% higher chance of vigorous activity participation.
Object control proficient children were more likely to become active adolescents. Motor skill development should be a key strategy in childhood interventions aiming to promote long-term physical activity.
横断面研究证据已证明运动技能熟练程度对身体活动参与的重要性，但尚不清楚技能熟练程度是否能预测随后的身体活动。
2000年，在一项学校干预中评估了儿童在物体控制（踢、接球、投掷）和移动（单脚跳、侧步急驰、垂直跳跃）技能方面的熟练程度。2006/07年，使用澳大利亚身体活动回忆问卷对以前参与者的身体活动进行了评估。线性回归分析了报告的青少年参与中度至剧烈或有组织的身体活动的时间与其童年技能熟练程度之间的关系，并对性别和年级进行了控制。逻辑回归分析了参与剧烈活动的概率。
在找到的481名原始参与者中，297名（62%）同意参与，276名（57%）接受了调查。所有参与者均为中学生，其中女生占52%（144名）。青少年参与中度至剧烈和有组织活动的时间与童年物体控制熟练程度呈正相关。相应模型分别解释了12.7%（p = 0.001）和18.2%的变异（p = 0.003）。物体控制熟练的儿童成长为青少年后，参与剧烈活动的可能性高出10%至20%。
物体控制熟练的儿童更有可能成为活跃的青少年。运动技能发展应成为旨在促进长期身体活动的儿童期干预的关键策略。
