本文以法学视角,尤其是国际法视角,通过研读规则文本的方式,对足球规则的演进进行分析,并且揭示一些目前体育法领域关注的问题:体育法(lex sportiva)确实存在,包含了公法部分(国际公约、国家立法)和私法部分(体育规则);体育规则(Laws of the game)是体育法的核心,包括国家、地区以及全球范围内各级体育主管部门的章程与条例;项目规则是体育法的另一个重要核心,作者以足球为例,论证了为什么项目规则也是法的问题。  相似文献

采用文献资料、录像观察、数理统计等方法,对参加第27届男篮亚锦赛的中伊男篮攻防数据进行定量、定性分析。结果表明:在场均攻防数据对比中,除了三分球和失误两指标接近外,中国队在各项指标上都要明显低于伊朗队;球队风格方面:伊朗队高强度防守、快节奏攻防转换是整体实力高于中国队的制胜因素;在各位置球员效率方面:中国队在内线方面较伊朗队仍有优势,但其他两位置能力明显不足,使球队整体"木桶效应"突显。  相似文献

PurposeThe present study investigated the effects of 16 weeks of small-volume, small-sided soccer training soccer group (SG, n = 13) and oscillating whole-body vibration training vibration group (VG, n = 17) on body composition, aerobic fitness, and muscle PCr kinetics in healthy inactive premenopausal women in comparison with an inactive control group (CO, n = 14).MethodsTraining for SG and VG consisted of twice-weekly 15-min sessions with average heart rates (HRs) of ∼155 and 90 bpm respectively. Pre- and post-measurements of body composition (DXA), phosphocreatine (PCr) on- and off-kinetics, and HR measurements during standardised submaximal exercise were performed.ResultsAfter 16 weeks of training in SG, fat percentage was lowered (p = 0.03) by 1.7% ± 2.4% from 37.5% ± 6.9% to 35.8% ± 6.2% and the PCr decrease in the quadriceps during knee-extension ramp exercise was attenuated (4% ± 8%, p = 0.04), with no changes in VG or CO (time-group effect: p = 0.03 and p = 0.03). Submaximal exercise HR was also reduced in SG after 16 weeks of training (6% ± 5% of HRmax, p = 0.01).ConclusionShort duration soccer training for 16 weeks appears to be sufficient to induce favourable changes in body composition and indicators of aerobic fitness and muscle oxidative capacity in untrained premenopausal women.  相似文献

Abstract

A concussion is a rare but potentially serious injury of football players. Thus, an immediate and valid diagnosis, estimate of severity and therapeutic management is required. To summarise the published information on management of concussion with respect to a safe return to play (RTP), a literature search was conducted. Current guidelines on concussion in sports and significant studies on concussion in football were analysed. After concussion, management and RTP decision should remain in the area of clinical judgement on an individualised basis according to the current international guidelines. If a concussion is suspected, the player should not be allowed to RTP the same day. The RTP programme should follow a gradual step-wise procedure. A concussed player should not RTP unless he/she is asymptomatic and the neurological and neuropsychological examinations are normal. Untimely RTP bears an increased risk of sustaining another more severe brain injury and repetitive brain injury of long-term sequelae. In football, the management of concussion should primarily follow the recommendations proposed by the Concussion in Sports Group. Information and education of players and their medical and coaching team help to protect the players’ health. Future studies on concussion should include validated and detailed information on RTP protocols.  相似文献

Abstract

Regular measurements of groin risk factors may offer a preventive measure against injury. Therefore, the aim of this study was to (1) determine minimal detectable change (MDC) and reliability of hip flexibility and strength measures and to (2) identify the effect soccer match play load has on these measures. Reliability was determined for bent knee fall out test, hip abduction and adduction (hand-held dynamometry (HHD)) in 20 trained youth male soccer players. Reliability was evaluated with the intra-class correlation coefficient (ICC[2,1]), 95% confidence intervals (CI). Hip strength and flexibility measures were taken before and after an international friendly match. Intra-rater reliability ICC ranges were bent knee fall out (0.75–0.90), abduction (0.83–0.90) and adduction (0.72–0.96). Inter-rater ICCs (95% CI) were bent knee fall out test [0.75 (0.39–0.90) right, 0.71 (0.27–0.89) left hip]; abduction [0.80 (0.50–0.92) right, 0.81 (0.53–0.92) left hip] and adduction [0.72 (0.31–0.89) right, 0.70 (0.26–0.88) left hip]. MDCs were as low as 20.7% of the mean for hip flexibility and 12.5% for strength. In conclusion, HHD and the bent knee fall out test are reliable tools to measure changes in hip strength and flexibility. Finally, a threshold may exist in which match play load negatively impacts hip flexibility.  相似文献

Abstract

The aim of this study was to compare the reliability, internal responsiveness and interchangeability of the Yo-Yo intermittent recovery test level 1 (YY1), level 2 (YY2) and submaximal YY1 (YY1-sub). Twenty-four young soccer players (age 17 ± 1 years; height 177 ± 7 cm; body mass 68 ± 6 kg) completed each test five times within pre- and in-season; distances covered and heart rates (HRs) were measured. Reliability was expressed as typical error of measurement (TEM) and intraclass correlation coefficient (ICC). Internal responsiveness was determined as effect size (ES) and signal-to-noise ratio (ESTEM). Interchangeability was determined with correlation between training-induced changes. The TEM and ICC for distances in the YY1 and YY2 and for HR in YY1-sub were 7.3% and 0.78, 7.1% and 0.93 and 2.2% and 0.78, respectively. The ESs and ESTEMs were 0.9 and 1.9 for YY1, 0.4 and 1.2 for YY2 and ?0.3 and ?0.3 for YY1-sub. Correlations between YY1 vs. YY2 and YY1-sub were 0.56 to 0.84 and ?0.36 to ?0.81, respectively. Correlations between change scores in YY1 vs. YY2 were 0.29 and ?0.21 vs. YY1-sub. Peak HR was higher in YY1 vs. YY2. The YY1 and YY2 showed similar reliability; however, they were not interchangeable. The YY1 was more responsive to training compared to YY2 and YY1-sub.  相似文献

Modern Korean sports have been adopted mostly from the West, but now Korea has emerged as a sporting power demanding global attention. The influence of historical and political ideology has been in the cultural background of Korean sports development, and the process of cultural evolution in soccer may be explained in the similar context. What helped the Korean soccer team qualify for the World Cup eight consecutive times – only the sixth country in the world to do so – thus making it the most powerful soccer team in Asia? Soccer initially appeared in Korea during the threat of Japanese invasion, and this backdrop provided the opportunity for soccer to be combined with nationalism and transformed into a cultural product that confronted Japanese imperialism. Since the Korean War, South Korean soccer has become a vehicle for ideological confrontation with North Korea amid the atmosphere of the Cold War, and it thus gave rise to sports nationalism by revealing an ideological superiority and nationalistic disposition. Soccer, which arrived in Korea on a British ship, has become a representative Korean sport and continuously challenges the global stage ahead of Asia's leading economic power. It was against the background of such rapid development that nationalism formed.  相似文献
