Sustained motivation for Daily Mile participation at higher physical activity intensities may contribute to the attainment of children's daily moderate-to-vigorous physical activity (MVPA) targets and long-term health benefits. However, individual variability exists in the amount of MVPA accumulated by children during the Daily Mile. The current study explored children's motivation for participating in the Daily Mile at MVPA intensity, using a theory of planned behaviour framework. Twenty-five children (mean age = 10.07 ± 0.60 years) from the Northwest of England were recruited to the study; 52% were female and 88% were White. Participants completed a questionnaire, with an open-ended response format, probing behavioural, control, and normative beliefs for participation in the Daily Mile at MVPA intensity. Template analysis was conducted independently by two researchers to identify main themes and subthemes. Findings showed that children possessed a range of behavioural, control, and normative beliefs about MVPA participation during the Daily Mile. Prominent behavioural beliefs included fitness enhancement, implications for concentration and learning, positive affective states, and pain and discomfort. Key control beliefs included weather, space and health restrictions, and distractions from peers. Finally, peers and parents were salient normative beliefs. Children possessed a range of modal beliefs in relation to MVPA participation during the Daily Mile. Implications of the findings, and methods for practitioners seeking to maximise the contribution of the Daily Mile to children's daily MVPA targets are discussed.

儿童在每日一英里中进行中度至剧烈体力活动的动机：计划行为理论视角

持续参与较高强度体育活动的每日一英里可能有助于实现儿童的日常中度至剧烈体育活动 (MVPA) 目标和长期健康益处。然而，儿童在每日一英里中积累的 MVPA 量存在个体差异。当前的研究利用计划行为框架理论探讨了儿童以 MVPA 强度参与每日一英里的动机。来自英格兰西北部的 25 名儿童（平均年龄 = 10.07 ± 0.60 岁）被招募参加该研究；52% 是女性，88% 是白人。参与者填写了一份问卷，采用开放式答复格式，探讨以 MVPA 强度参与每日一英里的行为、控制和规范信念。模板分析由两名研究人员独立进行，以确定主主题和副主题。调查结果显示，孩子们在每日一英里活动中对参与 MVPA 拥有一系列行为、控制和规范信念。突出的行为信念包括增强健康、对注意力和学习的影响、积极的情感状态以及疼痛和不适。主要的控制信念包括天气、空间和健康限制，以及同伴的干扰。最后，同龄人和父母是突出的规范信念。孩子们对于每日一英里参与 MVPA 有着一系列的模式信念。讨论了研究结果的意义以及寻求最大限度地提高每日里程对儿童每日 MVPA 目标的贡献的从业者的方法。
