Childhood Physical Fitness and Performance as Predictors of High School Sport Participation

ABSTRACT

Participation in youth sport is positively associated with physical fitness and performance. The purpose of the current study was to examine if physical fitness measures during childhood and early adolescence predicted high school sport participation. Participants included youth in the Michigan State University Motor Performance Study. Measures consisted of the endurance shuttle run, Wells sit-and-reach, jump and reach, standing long jump, agility shuttle run and 30-yard dash. Individual, generalized estimating equation models were used to estimate the association between each measure and the odds of participating in high school sport. For both sexes, the endurance shuttle run and agility shuttle run were related to sport participation. For boys only, the long jump and 30-yard dash were also associated with sport participation. Better physical fitness and performance across several dimensions in childhood, including those related to motor skills, enhanced the likelihood of sport participation in high school.  相似文献   

The effects of short versus long inter-set rest intervals in resistance training on measures of muscle hypertrophy: A systematic review     

Jozo Grgic  Bruno Lazinica  Pavle Mikulic  James W. Krieger  Brad Jon Schoenfeld 《European Journal of Sport Science》2017,17(8):983-993

Although the effects of short versus long inter-set rest intervals in resistance training on measures of muscle hypertrophy have been investigated in several studies, the findings are equivocal and the practical implications remain unclear. In an attempt to provide clarity on the topic, we performed a systematic literature search of PubMed/MEDLINE, Scopus, Web of Science, Cochrane Library, and Physiotherapy Evidence Database (PEDro) electronic databases. Six studies were found to have met the inclusion criteria: (a) an experimental trial published in an English-language peer-reviewed journal; (b) the study compared the use of short (≤60?s) to long (>60?s) inter-set rest intervals in a traditional dynamic resistance exercise using both concentric and eccentric muscle actions, with the only difference in resistance training among groups being the inter-set rest interval duration; (c) at least one method of measuring changes in muscle mass was used in the study; (d) the study lasted for a minimum of four weeks, employed a training frequency of ≥2 resistance training days per week, and (e) used human participants without known chronic disease or injury. Current evidence indicates that both short and long inter-set rest intervals may be useful when training for achieving gains in muscle hypertrophy. Novel findings involving trained participants using measures sensitive to detect changes in muscle hypertrophy suggest a possible advantage for the use of long rest intervals to elicit hypertrophic effects. However, due to the paucity of studies with similar designs, further research is needed to provide a clear differentiation between these two approaches.  相似文献   

The relative age effect on physical fitness in preschool children

ABSTRACT

The aim of the present study was to investigate the existence of a relative age effect (RAE) on physical fitness of preschoolers. Anthropometry and physical fitness were assessed in 3147 children (3–5 years old) using the PREFIT battery. Based on the birth year, participants were divided into 3year groups (3-, 4- and 5-years). Within each year group, 4quarter groups were created: quarter 1, preschoolers born from January to March; quarter 2, from April to June; quarter 3, from July to September; quarter 4, from October to December. The MANCOVA analysis revealed a main effect of year group (Wilks’ λ = 0.383; F_10,5996 = 369.64; p < 0.001, η_p ² = 0.381) and of quarter (Wilks’ λ = 0.874; F_15,8276.6 = 27.67; p < 0.001; η_p ² = 0.044) over the whole battery of tests. To the best of our knowledge, this is the first study to report the existence of RAE at the preschool stage. In general, performance improved as the relative age increased (i.e., those born in quarter 1 performed better than those in the other quarters). Individualization strategies should be addressed within the same academic year not only in elementary or secondary years but also in preschoolers.  相似文献   

Effectiveness of physical education to promote motor competence in primary school children     

Vítor P. Lopes  David F. Stodden  Luis P. Rodrigues 《Physical Education & Sport Pedagogy》2017,22(6):589-602

Background: Motor skill (MS) competence is an important contributing factor for healthy development.

Purpose: The goal was to test the effectiveness of primary school physical education (PE) on MS and physical fitness (PF) development.

Methods: Three classes (n?=?60, aged 9.0?±?0.9) were randomly assigned to three diverse conditions during a school year: two PE lessons/week (PE-2), three PE lessons/week (PE-3), and no PE lessons control group (CG). BMI, skinfolds, PF (9-min run/walk, sit-up, modified pull-ups), gymnastics, soccer, handball, basketball and track-and-field skills were evaluated. Effect sizes (d) were reported as magnitude of change.

Results: Skinfolds significantly increased only in CG (d?=?1.21). PF composite z-scores improved in PE-3 (d?=?0.61), but decreased in PE-2 (d?=?0.57), and had no changes in CG. Statistically significant improvement was verified in gymnastics and handball skills in both experimental groups (gymnastic: d?=?2.95 and d?=?2.61 for PE-3 and PE-2, respectively; handball: d?=?1.87 and d?=?0.57 for PE-3 and PE-2, respectively), and no changes were seen in CG. In soccer, there were improvements only in the PE-3 (d?=?0.55), and in basketball only in PE-2 (d?=?0.46). There were no changes in any group for track-and-field skills.

Conclusions: PE programs can effectively promote PF and MS development.  相似文献

危机与应对:新型冠状病毒肺炎疫情下的中国体育叙事     

孙科  郇昌店  任慧涛  闫士展  纪成龙  张震  王永顺 《上海体育学院学报》2020,(5):1-15,46

新型冠状病毒肺炎疫情(以下简称"疫情")下的体育叙事,不仅要阐发疫情期间体育事件及其社会意义,更应揭示不同体育要素在社会发展中的功能与作用,将对体育现实问题的思考转化为未来体育转型的应对策略。基于叙事的角度,以访谈的方式,探讨体育产业发展、东京奥运会延期、体育组织治理、奥运备战、居家体育、体育在线教学、体育中考等热点事件和话题。认为:①疫情对体育产业的影响呈现持续性、结构性、社会性等特征,在"转危为机"的话语下,应借助政府的积极行为,实现体育行业与体育产业的多层次融合,增强对消费端的刺激,提高体育企业的抗风险能力,最大程度地释放后疫情时代体育产业发展动力;②东京奥运会延期举办凸显国际奥委会内部治理的困境与危机,引发对中国体育赛事治理效能的思考,给奥运备战带来挑战,促使运动训练由传统化模式向集群化工业模式转变;③空间重叠与权力空间渗透造就居家体育的特殊"脱域"空间,成为"家庭-学校-社区"体育互动发展的催化剂,引发体育教学、社区体育、群众体育活动方式的改变,形成自觉行为更高的群众体育"在地化"驱动模式;④在疫情防控期间,体育话语在不同语境中的表达、转型与辩驳为体育话语转为文化资源提供契机,促进文化与体育的互动与整合,深刻影响人们的体育观念。  相似文献

摘要: 目的:对健身竞走的生物力学特征进行分析，以证实健身竞走是一项能够综合走与跑步优势的运动项目。方法:运用实验法、数理统计法，对普通人完成健身竞走、普通健身走和跑步的运动学、动力学指标进行统计分析。结果:无论在常速还是快速时,健身竞走与普通健身走在步长、步速、步频等方面有显著性差异；健身竞走更容易达到较高的速度和更大的运动强度，并且各关节的地面反作用力均非常显著小于常速跑步。结论:健身竞走有利于实现高效的健身效果，并且受伤的可能性小于跑步，是一项非常安全的运动项目，应进行广泛的推广。  相似文献   

全民健身品牌赛事长效化发展的志愿服务体系研究*     

康金峰  戴〓俊 《广州体育学院学报》2019,(1):45-48

全民健身运动是群众性的社会体育活动，是我国体育事业的重要组成部分，也是提高全民身体和心理素质的重要举措和途径。全民健身运动需要志愿服务的友爱、互助与支持，只有通过志愿服务者的无私奉献才能促进我国全民健身运动及有关赛事的长效发展，以打造出具有带动性和号召力的品牌赛事。由于我国的民众体育活动开展较晚，相应的志愿服务文化与价值观尚未形成，有关志愿服务的制度机制与组织体系并不完善。这就要求必须提高全民健身志愿服务的意识，完善有关制度机制与体系模式使我国全民健身志愿服务体系得到完善，使之走上长效化发展之路。  相似文献   

Blogadapting: Adaptation Experiences among Expatriate Bloggers     

Clark Callahan  Jesse King  Audrey Halversen 《Journal of Intercultural Communication Research》2020,49(3):227-241

ABSTRACT

Increased global communication is adjusting traditional models of cross-cultural communication. Specifically, changes in international communication processes have caused increased scrutiny of cross-culture adaptation theory. This is especially true when focusing on the difference between cultural adaptation and functional fitness. The purpose of this research is to address changes in global communications by testing to see if there is a difference between two important theoretical concepts within cross-cultural adaptation theory – linear and non-linear adaptation. Findings indicate that cultural sojourners do not equate cross-cultural adaptation with linear models of functional fitness. Models that equate the two should be revisited.  相似文献
