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.  相似文献   

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.  相似文献   

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

Helena Byrne 《Sport in History》2019,39(2):166-186

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.  相似文献   

The effects of a calf pump device on second half performance of a simulated soccer match in competitive youth players     

S. Béliard  J. Cassirame  G. Ennequin  G. Coratella  N. Tordi 《Journal of sports sciences》2019,37(6):708-716

During soccer matches, performance decrements have been reported that relate to both physical abilities and technical skills. To investigate the effects of low-frequency electrical stimulation LFES (VeinoplusSport®, Ad Rem Technology, France) administered during half-time recovery on performance alterations during the second half. Twenty-two highly trained young players undertook a soccer-match simulation (SAFT⁹⁰). During half-time, they were randomly assigned to LFES group or Placebo group. Each half was split into 3 bouts of 12 minutes. Following each bout, maximal strike speed (MSS), sprint test (ST), maximal sprint accelerations (MA) and metabolic power (MP) were determined in both groups. Arterial (AF) and venous flows (VF) were measured at rest and at the end of half-time. LEFS group exhibited beneficial effects on performance compared to the Placebo group with a likely effect for MSS, ST, MA, and a possible effect for MP. AF and VF increased statistically more in LEFS group compared to Placebo group. The use of specific calf-pump LFES during half-time of a youth simulated soccer match attenuated the decrease in performance during the second half compared to Placebo group. This effect is most marked at the beginning of the second half with regards to explosive parameters.  相似文献   

基于生物力学视角下对女子足球鞋发展的分析     

朱煜林 《教育教学论坛》2019,(18):107-109

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。  相似文献   

青少年运动员足球意识的培养与训练     

王永前 《河北职业技术学院学报》2006,6(3):82-84

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。  相似文献

Futsal task constraints promote transfer of passing skill to soccer task constraints     

Luca Oppici  Derek Panchuk  Fabio Rubens Serpiello  Damian Farrow 《European Journal of Sport Science》2018,18(7):947-954

This study investigated how learning a passing skill with futsal or soccer task constraints influenced transfer to a new task. Futsal (n?=?24, 13.6?±?1.2 years old, 7.0?±?1.6 years of experience) and soccer (n?=?24, 13.6?±?1.2 years old, 6.8?±?1.2 years of experience) players performed two 5v5?+?goalkeeper modified games – a futsal-like task (small playing area with the futsal ball) and soccer-like task (large playing area with the soccer ball). Participants’ passing accuracy and their orientation of attention were assessed during the two tasks. The futsal group improved their passing accuracy (ES?=?0.75?±?0.61) from the futsal-like to the soccer-like task, and they were more accurate than soccer players (ES?=?2.98?±?2.96). Conversely, the soccer group’s passing accuracy remained stable across the two tasks (ES?=?0.10?±?0.52) and it was similar to the futsal group in the futsal-like task (ES?=?0.58?±?1.93). This indicates a higher magnitude of transfer (and adaptability) from performing passes in a small playing area with short time to act – futsal task constraints – to a larger playing area with longer time – soccer task constraints – than vice-versa. Furthermore, the futsal group showed a higher adaptation of attention orientation to the affordances that emerged with the soccer task constraints, which is suggested to be one of the main mechanisms promoting skill transfer. These results encourage soccer practitioners to introduce futsal task constraints to fast-track players’ ability to functionally adapt perception–action coupling.  相似文献
