目的：以自我决定理论（Deci & Ryan，1987）为指导，本研究测试了一个跨情境模型，将青少年体育教练创建的社会环境感知与自主和控制动机水平联系起来，并客观测量青少年足球运动员的日常中等至剧烈身体活动（MVPA）和久坐时间（ST）。设计：该研究采用横断面设计，使用加速度计评估身体活动。方法：105名男性青少年运动足球运动员（M 年龄 = 12.79 +/- 1.85 岁）佩戴 GT3X 加速计 7 天。记录身高和体重的测量值。参与者完成了一份多部分的调查问卷，评估对自主支持和控制教练行为的看法，以及参与体育和身体活动游戏的动机。结果：路径分析支持一个模型，在该模型中，球员对教练提供的自主支持的看法积极预测了参与运动的自主动机。反过来，自主动机与 MVPA 呈正相关，与 ST（分钟/天）呈负相关。控制教练行为与控制动机呈正相关。然而，运动和身体活动游戏的受控动机与每日 MVPA 和 ST 无关。对教练提供的自主支持的看法对每日 MVPA 具有显着的正向间接影响，对每日 ST 具有显着的负向间接影响。结论：结果表明，教练的自主支持行为与年轻男性足球运动员的日常身体活动模式相关。基于理论的干预措施旨在鼓励自主支持性辅导，并随后培养自主参与体育运动的理由，可能会增强青少年体育的潜力，以增加活跃在这种环境中的儿童和青少年的每日 MVPA 并减少 ST (C) 2014 Elsevier Ltd. 保留所有权利。
Objective: Guided by self-determination theory (Deci & Ryan, 1987), this study tested a trans-contextual model linking perceptions of the social environment created by the youth sport coach to levels of autonomous and controlled motivation, and objectively measured daily moderate-to-vigorous physical activity (MVPA) and sedentary time (ST) in young football players.Design: The study employed a cross-sectional design, assessing physical activity using accelerometers.Method: 105 male youth sport footballers (M age = 12.79 +/- 1.85 years) wore a GT3X accelerometer for 7 days. Measures of height and weight were recorded. Participants completed a multi-section questionnaire assessing perceptions of autonomy support and controlling coaching behaviours, and motivation toward their participation in sport and physically active games.Results: Path analysis supported a model in which players' perceptions of coach-provided autonomy support positively predicted autonomous motivation for sport engagement. In turn, autonomous motivation was positively associated with MVPA, and negatively related to ST (min/day). Controlling coach behaviours were positively linked to controlled motivation. However, controlled motivation for sport and physically active games was unrelated to daily MVPA and ST. Perceptions of coach-provided autonomy support had a significant positive indirect effect on daily MVPA, and a significant negative indirect effect on daily ST.Conclusions: Results suggest that autonomy supportive coach behaviours are related to daily physical activity patterns in young male footbAllers. Theory-based interventions that aim to encourage autonomy supportive coaching, and subsequently foster autonomous reasons for sport engagement, may enhance the potential of youth sport for increasing daily MVPA and reducing ST among children and adolescents active in this setting (C) 2014 Elsevier Ltd.
