Association of fitness and quantified physical activity with psychological factors in elementary school children.

本研究以249名市郊公立学校和市区私立学校的四至六年级儿童为被试，采用三轴加速度计，结合消极和积极的心理因素，考察了健康、体力活动和不活动之间的关系。因此，通过问卷评估的客观评估的健康水平和身体缺乏活动与心理因素和每年缺勤次数独立相关，并根据生活方式和学校类型进行调整。然而，量化的体力活动只与一小部分心理因素有关。此外，该协会还间接地参与了学业成绩或学业不满足感。需要进行前瞻性研究，以检验上述因素之间的因果关系。

Present study examined the association of fitness, physical activity and inactivity quantified using a three-axis accelerometer with negative-and positive psychological factors, taking into account lifestyle and social factors, 249 fourth to sixth grades of children of public school in suburbs of local city and urban private school. As a result, objectively evaluated fitness level and physical inactivity assessed by a questionnaire were independently associated with psychological factors and number of absence per year, adjusting for the lifestyle and school type. However, quantified physical activity was associated only with a small part of the psychological factors. Further, the association was indirectly involved in academic performance or academic unsatisfactory feeling. Prospective study to examine the causal relationship among the above-mentioned factors is needed.
