The present study aimed to investigate positional differences in 744 high-level soccer players, aged 8 to 18 years. Players were assigned to six age groups (U9–U19) and divided into four playing positions (goalkeeper (GK), defender (DEF), midfielder (MF) and attacker (ATT)). MANOVA and effect sizes were used to examine anthropometrical and functional characteristics between all positions in all age groups. The main findings of the study were that GKs and DEFs were the tallest and heaviest compared with MFs and ATTs in all age groups. Further, between U9–U15, no significant differences in functional characteristics were found, except for dribbling skill, which MFs performed the best. In the U17–U19 age groups, ATTs seemed to be the most explosive (with GKs), the fastest and the more agile field players. These results suggest that inherent physical capacities (i.e., speed, power, agility) might select players in or reject players from an attacking position, which is still possible from U15–U17. Apparently, players with excellent dribbling skills at younger age are more likely to be selected to play as a MF, although, one might conclude that the typical physical characteristics for different positions at senior level are not yet fully developed among young soccer players between 8 and 14 years.  相似文献

We investigated changes in cardiorespiratory performance, BMI and leisure-time physical activity among Finnish adolescents from 2003 to 2010. In addition, we compared cardiorespiratory performance levels between normal weight and overweight adolescents, grouped according to their physical activity. Participants were a national representative samples of 15–16-year-old adolescents in their final (ninth) year of comprehensive school in 2003 (n = 2258) and in 2010 (n = 1301). They performed an endurance shuttle run test and reported their height and weight and leisure time physical activity on a questionnaire. Results showed no significant secular changes in cardiorespiratory performance from 2003 to 2010. The mean BMI increased in boys. Leisure-time physical activity increased among normal weight girls. Adolescents of normal weight had better cardiorespiratory performance than those classified as overweight at both assessment points. BMI-adjusted physical activity was a significant determinant for cardiorespiratory performance among overweight adolescents, and very active overweight adolescents had similar cardiorespiratory performance levels as moderately active adolescents of normal weight. The results of the present study support the idea that the physical activity has the great importance for the cardiorespiratory performance in adolescents. Overweight adolescents, in particular, benefit from higher levels of physical activity.  相似文献

试论学生良好健身习惯的养成     

张金棒 《安阳大学学报》2014,(2):95-97

坚持体育锻炼已是人人皆知的好习惯,但是在锻炼中间一些错误的方式方法,不仅会让运动效果大打折扣,如果方法不当,还可起到相反的作用,影响到身体健康。这不仅相悖于人们参加体育活动的初衷,而且还要承受不必要的痛苦,给自己、家人和学校带来负面影响。拥有了健康的身体才能更好地去学习,创造生活、享受生活。为了健康,我们应该积极地养成一个良好的健身习惯。在体育教学中教会学生运动技能很重要,使学生拥有一个正确的健身习惯更为重要。  相似文献   

从健康体适能看高校公共体育改革与发展趋势     

贾洪洲  朱文平 《许昌学院学报》2014,33(5):124-128

在对健康体适能理论分析的基础上,审视了当前我国高等学校公共体育存在的问题.大致有：选项教学等同于运动训练;体育教学内容重实践轻理论;体育教学评价指标以技能与竞技体适能为主忽视健康体适能;课余体育以竞赛类为主而忽视健身类活动;场地器材多以竞技体育为主.在健康第一思想指导下,依据健康体适能理论,未来高校公共体育改革与发展将呈现以下趋势：教学内容注重健身娱乐与生活化;俱乐部将成为主要教学模式之一;体育理论课受到重视;评价注重健康体适能测评技术;课余体育竞赛更加注重健身性与全体性.  相似文献
