A meta-analysis of maturation-related variation in adolescent boy athletes’ adaptations to short-term resistance training

This meta-analysis investigated the maturation-related pattern of adaptations to resistance training in boy athletes. We included studies examining the effects of 4–16-week resistance training programmes in healthy boy athletes aged 10–18 years. Pooled estimates of effect size for change in strength across all studies (n = 19) were calculated using the inverse–variance random effects model for meta-analyses. Estimates were also calculated for groups based on likely biological maturity status (“before”, “during” and “after” peak height velocity). Using the standardised mean difference, resistance training increased strength across all groups (effect size = 0.98, [CI: 0.70–1.27]). Strength gains were larger during (1.11 [0.67–1.54]) and after (1.01 [0.56–1.46]) peak height velocity than before (0.5 [?0.06–1.07]). Adaptations to resistance training are greater in adolescent boys during or after peak height velocity. These findings should help coaches to optimise the timing of training programmes that are designed to improve strength in boy athletes.     

The relationship between fundamental movement skill proficiency and physical self-confidence among adolescents

This study aims to assess fundamental movement skill (FMS) proficiency, physical self-confidence levels, and the relationship between these variables and gender differences among adolescents. Three hundred and ninety five adolescents aged 13.78 years (SD = ±1.2) from 20 schools were involved in this study. The Test of Gross Motor Development-2nd Edition (TGMD), TGMD-2 and Victorian Skills Manual were used to assess 15 FMS. Participants’ physical self-confidence was also assessed using a valid skill-specific scale. A significant correlation was observed between FMS proficiency and physical self-confidence for females only (r = 0.305, P < 0.001). Males rated themselves as having significantly higher physical self-confidence levels than females (P = 0.001). Males scored significantly higher than females in FMS proficiency (P < 0.05), and the lowest physical self-confidence group were significantly less proficient at FMS than the medium (P < 0.001) and high physical self-confidence groups (P < 0.05). This information not only highlights those in need of assistance to develop their FMS but will also facilitate in the development of an intervention which aims to improve physical self-confidence and FMS proficiency.     

Wartime imaginings of an archipelagic community: Fajar Asia and the quest for peninsula Malayan and Indonesian unity

During a brief period in the Japanese occupation of Southeast Asia, Malaya, including Singapore, was administratively placed with Sumatra under Japan’s 25th Army. From 28 March 1942 to April 1943, the two territories that had been separated by British and Dutch colonial rule since the mid-nineteenth century were considered one territory. This article explores how Malay intellectuals, through articles written in the magazine Fajar Asia, took advantage of this unprecedented opportunity to strive for a Malaya-Sumatra and Malaya-Indonesia community. This article will analyse the various wartime imaginings of a joint archipelagic community within the pages of Fajar Asia and highlight tensions within this project which resulted in an impasse as to how such a unity should or could be achieved.     

Compelling overuse injury incidence in youth multisport athletes

The present investigation was carried out to examine the incidence and pattern of injuries in adolescent multisport athletes from youth sports academy. Injury data were prospectively collected from 166 athletes during the seasons from 2009 to 2014. A total of 643 injuries were identified, 559 (87.0%) were time-loss injuries. The overall injury incidence was 5.5 (95% confidence interval CI: 5.1–6.0), the incidence of time-loss injuries was 4.8 (95% CI: 4.4–5.2), the incidence of growth conditions was 1.2 (95% CI: 1.0–1.4) and incidence of serious injuries was 0.6 (95% CI: 0.5–0.8) per 1000?h of exposure. The prevalence of overuse injuries was 50.3%. Growth conditions represented 20.0%. Most of the injuries (67.0%) involved the lower extremities, and both foot and ankle were the most predominant injured body parts (22.0%). Knee injuries were mostly from overuse (50 vs. 23, p?=?.02), whereas foot and ankle injuries resulted from an acute mechanism (94 vs. 31, p?<?.0001). Minor and moderate injuries accounted for 87.0%. Muscle, tendon and osteochondrosis injuries accounted for 52.0% of all injuries. Comparing groups, squash sport was having the highest injury incidence (8.5 injuries per athlete). Higher exposure was associated with greater overuse relative risk (RR?=?1.03, 95% CI: 1.01–1.014, p?<?.001). In conclusion, the results of this study identified a high incidence of injuries in this youth sports population. Striking was the prevalence of overuse injuries of 50%, which suggests the need for injury prevention protocols for adolescent highly trained athletes.     

Sport-specific factors predicting player retention in junior cricket

Understanding factors that motivate young athletes to continue participation in sport can help key stakeholders cultivate an environment that fosters long-term participation. This investigation sought to determine the performance and participation factors that influenced continued participation in junior cricket. Administration-level data were collected each annual season across a seven-year period by a community-level junior cricket association in Australia and analysed to identify the performance and participation-based predictors of player retention. All players were males aged <16 years. Players were categorised according to whether they remained in (or departed from) the association at the end of each playing season. A multivariate logistic regression model with a stepwise variable selection was employed to identify significant independent predictors of player retention. The number of innings batted and overs bowled were significant participation-related contributors to junior cricket player retention. Performance factors such as the number of wickets taken and the number of runs scored also significantly influenced player retention. Finally, team age group, the number of previous seasons played and age were also significant factors in player retention. This demonstrates that sufficient opportunity for children to participate in the game and expression of skills competence are key factors for retention in cricket.     

青奥会与奥运会遗产之比较

青奥会和奥运会的东道城市和国家越来越重视通过奥运赛事的承办为其创造"遗产".通过对既有文献资料的研究,进行逻辑分析,结合专家访谈,阐释"奥运遗产"概念的内涵,并从体育参与、社会进步、环境保护、城市建设和经济发展的角度分析青奥会和奥运会遗产的异同并讨论其原因.虽然青奥会与奥运会同属奥林匹克运动体系并一脉相承致使二者在奥运遗产方面有很多相似之处,但二者办赛理念和影响范围的迥异仍然可以体现在奥运遗产中.2007年后,青奥会和奥运会能够实现并存的原因在于各自不同的发展重心.发展的要求和现实的考验是青奥会和奥运会的共同议题,如果奥运会要以世界性大型赛会的社会经济发展的意义来度量"奥运遗产",青奥会就有必要从全球青少年通过体育所搭建的平台实现沟通与理解的角度来框架"奥运遗产"的范畴.区分与辨别所促进对于"奥运遗产"的理解并不是主要目的,面对2022年冬奥会的挑战,通过前期计划和组织影响"奥运遗产"的产生和作用才是当务之急.
