摘要

在世界范围内，青少年的中高强度体育活动(MVPA)减少，久坐行为(SB)增加。为了提高青少年的MVPA和降低SB，我们对他们的一天进行了分段分析，验证了每个人对每天60分钟建议的贡献。以前的研究只集中在体育活动的标记上，但没有比较SB变量，也没有比较学校休息时间与校外时间或周末。本研究旨在探讨青少年客观测量的PA和SB水平在天内和天间的差异。156名智利学生(87名男生和69名女生;M = 13.41岁;SD =。67岁)参加了本研究。用gt3x加速度计客观测量被试的PA和SB。总体结果显示，只有14%和9%的智利青少年分别在工作日和周末达到了每天60分钟的MVPA建议。研究发现，学校休息时间是发展MVPA的最佳时机，其次是校外时间，最后是周末，表现出最差的情况。在社交活动方面，智利青少年在工作日参与社交活动的时间占69.39%，在周末参与社交活动的时间超过70%。讨论了在一天中不同时段提高MVPA和降低SB的不同策略。

Within and between-day differences in adolescents’ objectively-measured physical activity and sedentary behavior

A decline in adolescents’ moderate-to-vigorous physical activity (MVPA) and the increase in their sedentary behavior (SB) have been registered all over the world. In order to increase the MVPA and reduce the SB of adolescents, their day has been analyzed by segments of time, verifying the contribution of each to the daily recommendation of 60 minutes/day. Previous studies have been centered only in physical activity markers, but the SB variables were not compared nor the segments of the school-recess with the out-of-school period or with the weekend. This study aimed to examine the intra- and inter-days differences in the objectively measured levels of PA and SB in adolescents. A sample of 156 Chilean school students (87 boys and 69 girls; M age=13.41; SD=.67 years) participated in the present study. Participants’ PA and SB were objectively measured by a GT3X accelerometer. Overall results showed that only 14% and 9% of Chilean adolescents achieved the daily recommendation of 60 minutes of MVPA on weekdays and the weekend, respectively. School recess was found the best moment for developing MVPA, followed by out-of-school time, and ending with weekend days presenting the worst scenario. Regarding the SB, Chilean adolescents were involved in SB 69.39% of the time on weekdays, and over 70% during the weekend. Different strategies are discussed in order to increase the MVPA and to decrease SB in each segment of a day.

期刊介绍： Kinesiology – International Journal of Fundamental and Applied Kinesiology (print ISSN 1331- 1441, online ISSN 1848-638X) publishes twice a year scientific papers and other written material from kinesiology (a scientific discipline which investigates art and science of human movement; in the meaning and scope close to the idiom “sport sciences”) and other adjacent human sciences focused on sport and exercise, primarily from anthropology (biological and cultural alike), medicine, sociology, psychology, natural sciences and mathematics applied to sport in its broadest sense, history, and others. Contributions of high scientific interest, including also results of theoretical analyses and their practical application in physical education, sport, physical recreation and kinesitherapy, are accepted for publication. The following sections define the scope of the journal: Sport and sports activities, Physical education, Recreation/leisure, Kinesiological anthropology, Training methods, Biology of sport and exercise, Sports medicine and physiology of sport, Biomechanics, History of sport and Book reviews with news.
