Motor skills are considered a prerequisite to physical activity, yet the relationship may be reciprocal and perceived sports competence might mediate associations.
In 2006/2007, 215 adolescents completed motor skill proficiency (Get Skilled Get Active), perceived sport competence (Physical Self-Perception Profile) and physical activity assessments (Adolescent Physical Activity Recall Questionnaire) as part of the Physical Activity and Skills Study. Using AMOS (Version 7.0), reciprocal relationships were examined between motor skill (object control and locomotor) and moderate to vigorous physical activity (MVPA). Both models were then run in different versions to understand the role of perceived sports competence as a potential mediator.
Mean age was 16.4 yr (SD=0.6), 51.6% (111/215) were females. A reciprocal relationship between object control and MVPA and a one-way relationship from MVPA to locomotor skill was found. When perceived sports competence was examined as a mediator, the best-fitting model versions explained 16% (R=0.16) MVPA variation, and 30% object control (R=0.30), and 12% locomotor skill variation (R=0.12) (reverse relationship). Perceived sports competence partially mediates the relationship between object control proficiency and physical activity for both directions and fully mediates the relationship between physical activity and locomotor skill; but only when locomotor skill is the outcome.
If the relationship between object control skill and physical activity is viewed as a "positive feedback loop," skill development and increasing physical activity should simultaneously be targeted in physical activity interventions. Increasing perceived sport competence should also be an intervention focus.
运动技能被认为是身体活动的前提条件,但两者之间的关系可能是相互的,而感知到的运动能力可能会调节这种关系。
2006/2007 年,215 名青少年完成了运动技能熟练程度(Get Skilled Get Active)、感知运动能力(Physical Self-Perception Profile)和身体活动评估(青少年身体活动回忆问卷),作为身体活动和技能研究的一部分。使用 AMOS(版本 7.0),考察了运动技能(物体控制和移动技能)与中等到剧烈的身体活动(MVPA)之间的相互关系。然后,以不同的版本运行这两个模型,以了解感知运动能力作为潜在中介的作用。
平均年龄为 16.4 岁(SD=0.6),51.6%(111/215)为女性。发现物体控制和 MVPA 之间存在相互关系,以及 MVPA 到移动技能的单向关系。当感知运动能力被视为中介时,最佳拟合模型版本解释了 16%(R=0.16)的 MVPA 变化,30%的物体控制(R=0.30)和 12%的移动技能变化(R=0.12)(反向关系)。感知运动能力部分中介了物体控制熟练程度与身体活动之间的关系,对于两个方向,以及完全中介了身体活动与移动技能之间的关系;但只有当移动技能是结果时才如此。
如果将物体控制技能与身体活动之间的关系视为“正反馈循环”,那么在身体活动干预中,技能发展和增加身体活动应该同时作为目标。提高感知运动能力也应该是干预的重点。
