足球运动员竞争力直观模型研究

参考构建直观模型的一般步骤,首先提出两个假设,并依此假设前提建立球员＂不完全＂竞争力直观模型,然后运用体育运动一般规律和竞争战略管理相关理论对模型的假设前提、内容和结构进行论证,最后探讨模型的应用价值和缺陷,展望模型扩展和优化的可能性。旨在通过对球员竞争力直观模型的探索,为球员、教练、球队、俱乐部等提供一种解决问题的思路。     

足球比赛的负荷量化-结构、方法和特征

足球比赛负荷是球员在比赛情景下完成各类动作所承受的物理、生理和心理等方面刺激之和。比赛负荷的量化结构分为外部和内部负荷,外部负荷的量化方法包括人工视频分析技术、自动轨迹追踪技术和全球定位设备,通过球员体能或技术表现的负荷量和强度来评定足球比赛中的行为活动特点,外部负荷特征表现为间歇性运动下频繁变向和短距离变速跑,高比例的中低强度无球跑穿插较少的高强度带球跑。内部负荷的量化方法包括耗氧量、心率和血乳酸等指标的测定,通过上述指标的变化幅度来评定足球比赛中的能量代谢水平;内部负荷特征表现为有氧供能为主、无氧磷酸原和糖酵解供能交替进行。现有研究局限为外部负荷低估了变向运动对足球比赛负荷的影响,内部负荷无法概括正式比赛的供能特征等。未来可尝试在优化量化方法基础上结合内外负荷,从而更精准地量化比赛负荷。     

New curve sprint test for soccer players: Reliability and relationship with linear sprint

ABSTRACT

The speed performance is involved not only in linear sprints, but also in a wide spectrum of multi-directional movements, such as curve sprinting. Curved sprint can be defined as sprint with gradual and continuous change of direction (COD). Although ~85% of the actions performed at maximum velocity in a professional soccer league are curvilinear sprints, there is not any specific test to assess this ability. This study aimed to analyse the reliability of a new curve sprint test, and compare its results with those obtained by soccer players in linear sprint. Forty experienced soccer players performed 3 attempts of curve sprint (using the penalty arc) to right and left side (17 m), and 3 linear sprints (17 m) in two different days. The ICCs (inter-session reliability) were 0.93 for sprint curve right side (CSRS) and 0.89 for sprint curve left side (CSLS), considered “acceptable”. The CVs (intra-session reliability) were 0.87% in CSRS and 1.15% in CSLS. The coefficient of determination (R²) between linear and curve sprinting was ~35%. The association between curve sides was “very large” (r = 0.878; p < 0.01). In summary, we showed that “curve sprint test” is highly reliable, and that curvilinear and linear sprints are different and independent actions.     

Evaluation of soccer players under the Moneyball concept

ABSTRACT

The recruitment of athletes with limited resources is a global problem in professional sports. In US Major League Baseball, the experience of the Oakland Athletics’ general manager in the last decade turned his “Moneyball” model into a synonym of quantitative analysis in the transfer market of baseball players. His strategy focused on hiring players with outstanding technical skills but relatively low market value. This study adapted this model to the framework of a multiple criteria decision aid (MCDA), by selecting undervalued players who have complementary abilities. The novelty here refers to the joint use of four algorithms explored by the composition of probabilistic preferences (CPP) (i.e., ranking, classification, dynamic evaluation and regularity analysis) and their application to soccer player performance evaluation. The new model analysed the recent transfer of a left-back soccer player to Europe. The results indicated 12 opportunities for better investment, among 32 left and right-back players considered. Two years later, the value of the same player was considerably lower. He played only five matches in the 2018–2019 season, without scoring or providing any assists. On the other hand, the players better classified by the CPP-MB model presented higher performances and market values.     

Where are we now? A review of research on the history of women's soccer in Ireland

ABSTRACT

It is a common fact that women's sport and leisure history, especially in male dominated spheres, and more specifically football, have been ignored by many academics. However, in recent years there have been major developments in digital technology that have changed the nature of the type of research that can be done. Access to tools to facilitate field research are relatively cheap and with the high volume of digitisation projects that have taken place over the last few years as well as the increasing number of born digital resources that have been published, there are new opportunities. In relation to women's soccer in Ireland, this paper asks the question – where are we now? The argument will review the current literature on this subject and outline potential approaches for future research.     

基于生物力学视角下对女子足球鞋发展的分析

本文采用文献资料法、数理统计法和归纳法,以生物力学为基础分析女子足球鞋对于女子运动员运动表现提高和运动损伤防治方面的必要性。结论表明:球鞋与场地表面的互相作用能够决定牵引力特性是否对运动员合适。挑选足球鞋鞋底构造应该根据场地条件或季节性变化而定。球鞋与场地相配合从而使运动员能够高效地做出动作和移动。球鞋的前部应与个人的足部形态相匹配。每个运动员的足部形态都不同,鞋与脚的正确搭配能帮助运动员保持他们的最佳表现。     

青少年运动员足球意识的培养与训练

意识对一个足球运动员来说非常重要,是衡量一名运动员水平高低的重要因素之一。足球意识的培养需要长期的训练、比赛的积累。青少年正是培养足球意识的黄金时期,但目前少年运动,尤其是学校业余运动员的初级训练,往往是重技术、轻意识;重结果、轻过程。为此有必要加强青少年足球运动员意识的培养与训练。
