Body composition assessment of English Premier League soccer players: a comparative DXA analysis of first team,U21 and U18 squads     

Jordan Milsom  Robert Naughton  Andy O’Boyle  Zafar Iqbal  Ryland Morgans  Barry Drust 《Journal of sports sciences》2015,33(17):1799-1806

Professional soccer players from the first team (1st team, n = 27), under twenty-one (U21, n = 21) and under eighteen (U18, n = 35) squads of an English Premier League soccer team were assessed for whole body and regional estimates of body composition using dual-energy X-ray absorptiometry (DXA). Per cent body fat was lower in 1st team (10.0 ± 1.6) compared with both U21 (11.6 ± 2.5, P = 0.02) and U18 (11.4 ± 2.6, P = 0.01) players. However, this difference was not due to variations (P = 0.23) in fat mass between squads (7.8 ± 1.6 v 8.8 ± 2.1 v 8.2 ± 2.4 kg, respectively) but rather the presence of more lean mass in 1st team (66.9 ± 7.1 kg, P < 0.01) and U21 (64.6 ± 6.5 kg, P = 0.02) compared with U18 (60.6 ± 6.3 kg) players. Accordingly, fat mass index was not different (P = 0.138) between squads, whereas lean mass index was greater (P < 0.01) in 1st team players (20.0 ± 1.1 kg · m^?2) compared with U18 players (18.8 ± 1.4 kg · m^?2). Differences in lean mass were also reflective of higher lean tissue mass in all regions, for example, upper limbs/lower limbs and trunk. Data suggest that training and nutritional interventions for younger players should therefore be targeted to lean mass growth as opposed to body fat loss.  相似文献   

Angle-specific hamstring-to-quadriceps ratio: A comparison of football players and recreationally active males     

Pavlos Eleftherios Evangelidis  Matthew Thomas Gerard Pain  Jonathan Folland 《Journal of sports sciences》2015,33(3):309-319

It is currently unclear how football participation affects knee-joint muscle balance, which is widely considered a risk factor for hamstrings injury. This study compared the angle-specific functional hamstring-to-quadriceps (H:Q) ratio (hamstrings eccentric torque as a ratio of quadriceps concentric torque at the same knee-joint angle) of football players with recreationally active controls. Ten male footballers and 14 controls performed maximal voluntary isometric and isovelocity concentric and eccentric contractions (60, 240 and 400° s^?1) of the knee extensors and flexors. Gaussian fitting to the raw torque values was used to interpolate torque values for knee-joint angles of 100–160° (60° s^?1), 105–160° (240° s^?1) and 115–145° (400° s^?1). The angle-specific functional H:Q ratio was calculated from the knee flexors eccentric and knee extensors concentric torque at the same velocity and angle. No differences were found for the angle-specific functional H:Q ratio between groups, at any velocity. Quadriceps and hamstrings strength relative to body mass of footballers and controls was similar for all velocities, except concentric knee flexor strength at 400° s^?1 (footballers +40%; P < 0.01). In previously uninjured football players, there was no intrinsic muscle imbalance and therefore the high rate of hamstring injuries seen in this sport may be due to other risk factors and/or simply regular exposure to a high-risk activity.  相似文献   

Asian Football: A Cesspool of Government Interference,Struggles for Power,Corruption, and Greed     

James M. Dorsey 《国际体育史杂志》2015,32(8):1001-1015

Arab politics have been written into the DNA of the Asian Football Confederation (AFC) starting with the expulsion of Israel in 1974. The expulsion like that of Taiwan the same year underscored the incestuous relationship between politics and sport that is among the most prevalent in the Middle East and North Africa despite self-serving denials by the high and mighty of regional and international sports. A failure by world soccer body FIFA in the cases of both Israel and Taiwan to follow through on threats to sanction the AFC for violating the charters of the world and Asian soccer body with the expulsions has shaped global soccer's attitude towards autocratic regimes. In the Middle East and North Africa, FIFA's and the AFC's refusal to insist on adherence by national associations to their principles, rules, and regulations amounted to effective support for autocratic rule in a soccer crazy region where rulers see the game as a key tool to retain power by exercising absolute control of public space and an institution that evokes deep-seated passions.  相似文献   

‘Not Merely an Isolated Game’: Women’s Association Football in Australia     

Greg Downes  Ian Syson  Roy Hay 《国际体育史杂志》2015,32(18):2150-2170

ABSTRACT

Australia has participated in the world-wide growth of women’s football particularly since the 1970s, but long before that the game was played recreationally and competitively by women in Australia. Women have struggled to overcome active opposition to their taking part in the sport and neglect of their achievements which are considerable. This article provides an outline of the history of the game both nationally and in its international context. It also tries to capture the experience of some of the pioneers of the women’s game and its modern practitioners, revealing some of the ways in which overt and covert discrimination still hinders recognition of their achievements.  相似文献   

不同颗粒密度人造草坪对足球运动员运动表现及损伤的影响     

杨辰  曲峰  万祥林 《体育科学》2015,(2):61-66,80

目的:揭示人造草坪不同颗粒填充密度对足球运动员侧切和起动动作表现的影响,并通过动作过程的生物力学数据分析可能的损伤危险。方法:13名男子足球运动员分别在3种不同颗粒密度的人造草坪上进行45°侧切和直线起动动作,采集运动学和动力学数据。结果:随着颗粒密度的增加,鞋与草坪交互面牵引力增大;侧切制动阶段地面反作用力峰值和加载率增大,地面反作用力首次峰值时刻的垂直、前、后分力增大,膝伸力矩增大,内收力矩和外展角度减小;蹬伸阶段地面反作用力分量增大;直线起动的重心加速度无显著差异。结论:鞋与人造草坪交互面的牵引力随填充颗粒的密度增加而增加;在常速助跑情况下,较大的交互面牵引力可以为侧切提供良好的制动能力和蹬伸推进力,但不会对直线起动的运动表现造成影响;交互面牵引力的增大会引起侧切制动阶段地面反作用力相关指标的增大,造成地面反作用力峰值时刻ACL损伤敏感指标的改变,导致更大的损伤风险。  相似文献
