本研究的目的是确定有组织的运动参与日常体力活动（PA）的贡献作用，并描述训练过程中的PA。7-12岁的儿童佩戴加速度计1周。分析中纳入了至少5天活动数据的儿童（n = 492）。Evenson临界点用于提取全天和训练期的PA数据。采用两种方法评估PA建议的依从性-每周平均值和每日数据。超过一半（52.5%）的儿童每周至少参加一次有组织的体育活动。每周参加三次或更多次有组织的运动增加了符合PA建议的几率（平均法：OR = 4.02，95%CI：1.98-8.19，p < 0.001，天数法：OR = 2.82，95%CI：1.35-5.88，p = 0.006）。平均而言，儿童在训练期间获得了23.3 +/- 15.3分钟的中度至剧烈PA（MVPA），而男孩比女孩积累了更多的MVPA分钟（β = 5.2，95% CI：2.4-8.0），并且MVPA的训练时间分别随年龄而减少（β =-1.0，95% CI：-1.9至-0.1）。训练期间每增加一分钟MVPA，每日MVPA增加1.3分钟（95% CI：1.1-1.5）。与未接受训练的儿童相比，接受训练的儿童累积的MVPA分钟数增加了24.9（95% CI：21.8-28.0）。总之，这些研究结果突出了有组织的体育运动在支持儿童PA水平的重要性。然而，仅参加有组织的运动不足以满足PA的建议，因此，PA应全天支持。
The purpose of this study was to determine the contributing role of organised sport participation to daily physical activity (PA) and to describe the PA during training. Children aged 7-12 wore the accelerometer for 1 week. Children with activity data for a minimum of 5 days were included in the analysis (n = 492). Evenson cut-points were used to extract PA data for whole day and training sessions. Compliance with PA recommendations was assessed with two methods - weekly average and daily data. More than half (52.5%) of the children participated in an organised sport at least once a week. Participation in organised sport three or more times a week increased the odds of meeting PA recommendations (average method: OR = 4.02, 95% CI: 1.98-8.19, p < 0.001, days method: OR = 2.82, 95% CI: 1.35-5.88, p = 0.006). On average, children acquired 23.3 +/- 15.3 min of moderate to vigorous PA (MVPA) during trainings, while boys accrued more MVPA minutes compared to girls (beta = 5.2, 95% CI: 2.4-8.0) and the training time MVPA decreased with age (beta = -1.0, 95% CI: -1.9 to -0.1), respectively. Each additional MVPA minute during training increased daily MVPA by 1.3 min (95% CI: 1.1-1.5). On days with training children accumulated 24.9 (95% CI: 21.8-28.0) more MVPA minutes compared to days without training. In conclusion, these findings highlight the importance of organised sport in supporting the PA levels of children. However, participation in the organised sport only is not sufficient to meet PA recommendations, and therefore, PA should be supported throughout the day.
