Abstract

Context

Across adolescence, there is a notable decline in physical activity in boys and girls. Maturational timing may be a risk factor for disengagement from physical activity and increased sedentary behaviours during adolescence.

Objective

This systematic review aimed to summarise literature that examined the relationship between maturational timing, physical activity and sedentary behaviour in adolescents.

Methods

Six electronic databases were searched for articles that assessed biological maturation and physical activity (including sports participation and active transportation) or sedentary behaviours in adolescents. Two reviewers conducted title, abstract, and full-text screening, reference and forward citation searches. Included articles were evaluated for quality using a standardised tool. A narrative synthesis was used to analyse the findings due to the heterogeneity of the studies.

Results

Searches yielded 78 articles (64 unique studies) that met the inclusion criteria, representing 242,316 participants (153,179 unique). Studies ranged from 30.0% (low) to 91.7% (high) in quality. An inverse relationship between maturational timing and physical activity (in 50 and 60% of studies in boys and girls, respectively) and a positive relationship between maturational timing and sedentary behaviour (in 100% and 53% of studies in boys and girls, respectively) was most commonly reported. Evidence supporting an association between maturational timing, sports participation, and active transportation was inconsistent.

Conclusions

While this review demonstrates some evidence for early maturational timing as a risk factor for disengagement from physical activity and increase in sedentary behaviours, the reviewed literature also demonstrates that this relationship is complex. Future research that tracks maturity-related variations in physical activity and sedentary behaviours over adolescence is warranted.

探索青春期生物成熟度，体育活动和久坐行为之间的关系：系统综述和叙述性综合

摘要

语境

在整个青春期，男孩和女孩的体育活动显着下降。成熟的时机可能是脱离体育活动和增加青春期久坐行为的危险因素。

目的

本系统综述旨在总结研究青少年成熟时间，身体活动与久坐行为之间关系的文献。

方法

在六个电子数据库中搜索了评估青少年的生物成熟度和身体活动（包括运动参与和积极运输）或久坐行为的文章。两名审稿人进行了标题，摘要和全文筛选，参考文献和正向引文检索。使用标准化工具评估了纳入文章的质量。由于研究的异质性，叙述性综合用于分析发现。

结果

搜索产生了符合纳入标准的78篇文章（64项独特研究），代表242,316名参与者（153,179项独特）。研究的质量范围从30.0％（低）到91.7％（高）。成熟时间与身体活动成反比关系（分别在男孩和女孩的研究中占50％和60％）和成熟时间与久坐行为之间正相关（在男孩和女孩中分别占研究的100％和53％）最常被报道。支持成熟时间，运动参与和积极交通之间联系的证据不一致。

结论

虽然这篇综述表明了一些成熟早的证据，这些证据是脱离体育活动和增加久坐行为的危险因素，但综述的文献也表明这种关系很复杂。有必要进行进一步的研究来跟踪青春期与身体活动和久坐行为有关的成熟度变化。
