Possessing positive physical perceived competence is important for physical activity in older children. Young children are primarily physically active through play-based behaviour rather than through organised sports and activities, so understanding how play perceptions might influence physical activity behaviour is important. The study purpose was to assess if perceived active play competence is associated with young children's physical activity.
Cross sectional study.
This paper uses two different samples drawn from the same Australian city, both collected in 2013. The first sample included 152 children (49% boys) aged 4-5 years (M=4.7, SD=0.47), the second sample included 78 children (55% boys) aged 5-8 years (M=6.6, SD=0.93). The Pictorial Scale of Perceived Movement Skill Competence was used to assess children's perceived competence in six skill-related play activities. Moderate- to vigorous-intensity physical activity (MVPA) was assessed for 8 consecutive days via accelerometers. A general linear model with the mean minutes in MVPA per day as the outcome, perceived play competence as the independent variable and adjusting for relevant confounders was performed in each sample.
Perceived active play competence was not related to MVPA min/day (B=0.44, p=0.323) in the younger sample, but was in the older sample (B=1.53, p=0.026), explaining 24% of adjusted variance.
Positive findings in the older sample show school-aged children need exposure to play based activities in order to develop the positive self-perception needed to engage in MVPA every day.
拥有积极的身体感知能力对大龄儿童的体育活动很重要。幼儿主要通过基于游戏的行为进行身体活动,而非通过有组织的体育和活动,因此了解游戏认知如何影响身体活动行为很重要。本研究的目的是评估感知到的积极游戏能力是否与幼儿的身体活动相关。
横断面研究。
本文使用了来自澳大利亚同一城市的两个不同样本,均于2013年收集。第一个样本包括152名4至5岁的儿童(49%为男孩)(均值=4.7,标准差=0.47),第二个样本包括78名5至8岁的儿童(55%为男孩)(均值=6.6,标准差=0.93)。使用感知运动技能能力图片量表来评估儿童在六项与技能相关的游戏活动中的感知能力。通过加速度计连续8天评估中度至剧烈强度的身体活动(MVPA)。在每个样本中进行一个以每天MVPA的平均分钟数为结果、感知游戏能力为自变量并对相关混杂因素进行调整的一般线性模型。
在较年幼的样本中,感知到的积极游戏能力与每天MVPA的分钟数无关(B=0.44,p=0.323),但在较大的样本中相关(B=1.53,p=0.026),解释了24%的调整后方差。
较大样本中的积极结果表明,学龄儿童需要接触基于游戏的活动,以培养每天参与MVPA所需的积极自我认知。
