Participation in physical activity (PA) is reported to decline in adolescence, particularly for girls. However, we do not know if this decline in PA is consistent across modes and settings or whether there are transfers of participation between modes and settings. Nor do we understand the changes in specific types of PA or the interaction between types of participation and different modes/settings. This study investigated contexts of PA participation for female adolescents at two life transition points.
A survey of 489 Year 7 and 243 Year 11 adolescent girls was conducted, incorporating a measure of overall PA level and participation rates in seven modes/settings and in specific types of sport and PA.
Less than half of the respondents met or exceeded the recommended level of moderate or vigorous PA--60 min or more--on the previous day, and there was no statistically significant difference in the proportions in Years 7 and 11 (39.5% vs. 45.9%; p > .05). However, older adolescents shifted their participation away from organized, competitive modes and settings toward nonorganized and noncompetitive modes and settings and individual types of PA.
An understanding of the changes in PA modes and settings identified here can inform the planning of policies and implementation of programs for the promotion of PA by adolescent girls.
有报道称,青少年的体力活动(PA)参与度会下降,尤其是女孩。然而,我们并不清楚 PA 参与度的这种下降是否在所有模式和环境中都一致,或者是否存在不同模式和环境之间的参与转移。我们也不了解特定类型的 PA 的变化情况,以及参与类型与不同模式/环境之间的相互作用。本研究调查了女性青少年在两个人生转折点的 PA 参与情况。
对 489 名 7 年级和 243 名 11 年级的少女进行了一项调查,调查内容包括总体 PA 水平以及在七种模式/环境中和特定类型的运动和 PA 中的参与率。
不到一半的受访者在前一天达到或超过了建议的中度或剧烈 PA 水平——60 分钟或更长时间,7 年级和 11 年级的比例没有统计学上的显著差异(39.5%比 45.9%;p>.05)。然而,年龄较大的青少年逐渐远离有组织、竞争的模式和环境,转而参与非组织、非竞争的模式和环境,以及个体类型的 PA。
对这里确定的 PA 模式和环境的变化的理解,可以为制定促进少女 PA 的政策和实施计划提供信息。
