1与青少年有氧能力相关的10个问题显示文摘峰值摄氧量(pO_2)是国际公认的青少年有氧能力评估标准,尽管有近八十年的青少年数据,但对它的解释以及它与青少年儿童成长和成熟过程中其他健康相关变量的关系,仍存在争议。有关青少年有氧能力可训练性的争论从未停止,仍然需要解决训练导致变化的因果机制以及根据年龄、生物性成熟、性别等因素进行调整。青少年日常体育活动的特点是间歇性进行和强度的迅速变化,但大多数青少年很少进行用来确定峰值摄氧量的强度和持续时间的体育活动。在这个背景下,肺部摄氧量的瞬态动力学就可以最好地反映青少年的有氧能力。对不同强度运动开始时青少年肺部摄氧量动力学的严格研究非常少,而在运动强度的阶跃变化中,实足年龄、生物性成熟和性别因素的影响并没有得到充分证实。了解青少年肺部摄氧量动力学参数的可训练性主要基于对运动员和非运动员的少量比较研究,对训练导致变化的根本机制仍需进一步探索。文章的目标是对成长和成熟过程中的有氧能力提供简要概述,提高对其评估和解释争议的认识,找出知识差距,提出10个相关的研究问题,并指出未来研究的潜在领域。 朱为模(审校) 2018体育科研2018,39,2:5
2Physical activity,physical fitness,diet and the health in young people显示文摘The beneficial effects of appropriate physical activity(PA), physical fitness,and diet during adult life are well-documented but the potential of appropriate PA,physical fitness,and diet to confer benefits on health and well-being during childhood and adolescence has not been explored fully.Recognizing the value of critical reviews of the extant literature in providing a foundation for future research,the Journal of Sport and Health Science(JSHS) has commissioned two Special IssuesNeil Armstrong Sulin Cheng J.Larry Durstine 2012Journal of Sport and Health Science2012,1,3:1

7The Development of Aerobic and Anaerobic Fitness with Reference to Youth Athletes显示文摘Purpose To challenge current conventions in paediatric sport science and use data from recent longitudinal studies to elu-cidate the development of aerobic and anaerobic fitness,with reference to youth athletes.Methods(1)To critically review the traditional practice of ratio scaling physiological variables with body mass and,(2)to use multiplicative allometric models of longitudinal data,founded on 1053(550 from boys)determinations of 10-17-year-olds’peak oxygen uptake(VO2)and 763(405 from boys)determinations of 11-17-year-olds’peak power output(PP)and mean power output(MP),to investigate the development of aerobic and anaerobic fitness in youth.Results The statistical assumptions underpinning ratio scaling of physiological variables in youth are seldom met.Multiplicative allometric modelling of longitudinal data has demonstrated that fat free mass(FFM)acting as a surrogate for active muscle mass,is the most powerful morphological influence on PP,MP,and peak VO2.With FFM appropriately controlled for,age effects remain significant but additional,independent effects of maturity status on anaerobic and aerobic fitness are negated.Conclusions Ratio scaling of physiological variables with body mass is fallacious,confounds interpretation of the develop-ment of anaerobic and aerobic fitness,and misleads fitness comparisons within and across youth sports.Rigorous evalua-tion of the development of anaerobic and aerobic fitness in youth requires longitudinal analyses of sex-specific,concurrent changes in age-and maturation-driven morphological covariates.Age and maturation-driven changes in FFM are essential considerations when evaluating the physiological development of youth athletes.Neil Armstrong Jo Welsman 2020Journal of Science in Sport and Exercise2020,2,4:1

11对《与青少年有氧能力相关的10个问题》一文评论的回应显示文摘针对Dotan对《与青少年有氧能力相关的10个问题》的点评和后续讨论而得的《儿童有氧运动能力可训练性及相关问题》一文进行反馈,对Dotan提出的'现有的最大耗氧量数据的有效性''儿童有限的有氧运动可训练性——是事实还是虚构?''缺乏长期、纵向训练研究''没有对儿童成年人的训练进行直接比较''对儿童们声称的可训练性较低的合理解释''训练质量''其他可能的影响''缺乏VO_2稳定期''肺部VO_2动力学(pO_2)''未来研究'几方面问题进行逐一解答,以强调《与青少年有氧能力相关的10个问题》(下简称《10个问题》)一文的讨论重点为青少年有氧适能的发展,而非儿童—成人差异。以成年人为研究对象的部分相关文献并未收录入《10个问题》中,因此Dotan的许多评论对于《10个问题》一文属于次要意见,需要在此特定背景下加以考虑。Neil Armstrong 朱为模 2018体育科研2018,39,2:1

19年轻人是健康且积极的——事实还是假象?(英文)显示文摘本文参照了前几代人的状况,研究年轻人的日常性体力活动及有氧健身与健康和幸福的关系。数据一直显示,男孩比女孩更加积极参加与健康相关的体力活动,并且两者在青春期时对体力活动的热情都会下降。大多数年轻人(约60%-75%)未达到当前与健康相关的体力活动指南的要求,但是在过去的20多年里,年轻人的日常性体力活动趋于稳定。峰值摄氧量(peakVO2)被认为是最好的单一有氧运动测量方法,尽管它没有描述有氧运动的所有方面。随着年龄增长,身体生长及逐渐成熟,PeakVO2也逐渐提高,男孩和女孩从8岁到16岁会各增加150%和80%。在整个儿童和青少年期,男孩的PeakVO2值会一直高于女孩,到16岁时,性别差异会达到35%。没有强有力的证据证明年轻人比前几代人的peakVO2水平低或在有氧健身方面较差。在过去的35年里,年轻人尽管PeakVO2相对稳定,但进行包括体质量运输的最大有氧运动的能力降低了约13%。日常生活中,年轻人极少通过高强度和耐力的体力活动来加强有氧运动,并且PeakVO2最多只是与年轻人当前的日常性体力活动水平弱相关。在促进年轻人健康和幸福方面,低水平的日常性体力活动和显著持续下降的最大有氧运动仍是主要问题。Neil Armstrong 2012Journal of Sport and Health Science2012,1,3:0
20对儿童运动代谢的新认识(英文)显示文摘Research in paediatric exercise metabolism has been constrained by being unable to interrogate muscle in vivo.Conventionally,research has been limited to the estimation of muscle metabolism from observations of blood and respiratory gases during maximal or steady state exercise and the analysis of a few muscle biopsies taken at rest or post-exercise.The purpose of this paper is to review how the introduction of 31P-magnetic resonance spectroscopy and breath-by-breath oxygen uptake kinetics studies has contributed to current understanding of exercise metabolism during growth and maturation.Methodologically robust studies using 31P-magnetic resonance spectroscopy and oxygen uptake kinetics with children are sparse and some data are in conflict.However,it can be concluded that children respond to exercise with enhanced oxygen utilization within the myocyte compared with adults and that their responses are consistent with a greater recruitment of type I muscle fibres.Changes in muscle metabolism are age,maturation- and sex-related and dependent on the intensity of the exercise challenge.The introduction of experimental models such as 'priming exercise' and 'work-to-work' transitions provide intriguing avenues of research into the mechanisms underpinning exercise metabolism during growth and maturation.Neil Armstrong Alan R.Barker 2012Journal of Sport and Health Science2012,1,1:0
