Quantifying coordination among the rearfoot,midfoot, and forefoot segments during running

Because previous studies have suggested that there is a relationship between injury risk and inter-segment coordination, quantifying coordination between the segments is essential. Even though the midfoot and forefoot segments play important roles in dynamic tasks, previous studies have mostly focused on coordination between the shank and rearfoot segments. This study aimed to quantify coordination among rearfoot, midfoot, and forefoot segments during running. Eleven healthy young men ran on a treadmill. The coupling angle, representing inter-segment coordination, was calculated using a modified vector coding technique. The coupling angle was categorised into four coordination patterns. During the absorption phase, rearfoot–midfoot coordination in the frontal planes was mostly in-phase (rearfoot and midfoot eversion with similar amplitudes). The present study found that the eversion of the midfoot with respect to the rearfoot was comparable in magnitude to the eversion of the rearfoot with respect to the shank. A previous study has suggested that disruption of the coordination between the internal rotation of the shank and eversion of the rearfoot leads to running injuries such as anterior knee pain. Thus, these data might be used in the future to compare to individuals with foot deformities or running injuries.     

高校课外体育活动中运动损伤的调查分析与防治

高校课外体育活动是实现高校体育教育目标的一个重要途径。但是活动中由于缺乏有力的预防措施,屡见不鲜的运动损伤正困扰着课外体育活动的正常开展。我们在对衡水师专上公共体育课的学生开展运动损伤调查分析的基础上,阐述了120名学生运动损伤的发病特点、规律和原因,提出了搞好预防运动损伤的具体措施。

我国排球运动员的运动创伤情况调查研究

为了探索我国排球运动员创伤发生的规律,从而为寻找预防和减少训练及比赛中的创伤提供依据,对我国419名排球运动员进行了创伤流行病学调查。调查结果表明,我国排球运动员运动损伤发生率为2.6人次/1000h,所有受试者在训练中损伤的发生率为1.8人次/1000h,比赛中的损伤发生率为4.1人次/1000h,踝关节损伤发生率是1人次/1000h,是排球运动中的最常见损伤。     

Injuries during football tournaments in 45,000 children and adolescents

Four percent of the world’s population, or 265 million people, play football, and many players are injured every year. The present study investigated more than 1800 injuries in over 45,000 youth players participating in three consecutive international football tournaments in Denmark in 2012–2014. The aim was to investigate the injury types and locations in children and adolescent football players and the differences between genders and age groups (11–15 and 16–19 years of age). An overall injury rate of 15.3 per 1000 player hours was found. The most common injury location was lower extremities (66.7%), and the most common injury type was contusion (24.4%). Girls had a relative risk of injury of 1.5 compared with boys, p?injuries to knee and lower leg, 23.8%, than boys, 19.0%, p?p?injuries that may be expected at a large youth football tournament. These findings are of great value for organizations and healthcare professionals planning similar events and for planning injury prevention strategies, which would be of special interest in the youngest female players in general.     

学校对中小学生校园伤害的责任探析

中小学和学生的关系是一种由教育法规定的教育管理关系 ,学校对学生的教育管理责任是学校对校园发生的学生人身伤害案件承担法律责任的法律依据。学校不是也不能成为学生的监护人 ,对学生没有监护责任。学校在履行教育管理职责中的过失使在校学生遭到人身伤害 ,学校应当承担责任。反之 ,在学生及其监护人有过错的情况下 ,应当减轻或免除学校的责任

对广西初中生体育活动运动损伤的调查与分析

本文采用问卷调查法、数理统计法和逻辑分析的方法,对广西初中学生的运动损伤情况进行统计分析,发现这些人的损伤大部分是集中在四肢,以轻伤和中度伤害为主。主要是因为场地不好,缺乏必要的知识和医疗监督等原因造成的。     

体育活动侵权适用自甘风险条款的规制与限度 ——基于《民法典》

《民法典》第1176条自甘风险规则主要适用于文体活动，是对体育行业诉求和司法实践活动的立法回应。自甘风险规则的构成要件及排除性条件包括：限定在文体活动范畴，适用于一定风险的文体活动，存在故意或者重大过失的情形，体育场馆经营者、管理者和体育活动组织者的安全保障义务。自甘风险规则不可窄化理解，也不可扩大解释。立法背景下的“文体活动”是指文化和体育活动，“一定风险”是指体育活动中的固有风险；有必要厘清体育意义上的“故意犯规”行为和法律意义上的“故意伤害”行为。自甘风险规则在名义上是一种独立的抗辩事由，属于完全阻却事由，实质上该条款作为独立抗辩事由的法律效力大打折扣。在司法实践中，应当遵循体育运动的基本规律，综合考虑各种衡平因素，视具体问题和情形进行具体分析。自甘风险规则对法庭质证环节的客观性、严谨性、专业性提出了更高的要求，基于体育专业视角的司法实践内容将发挥更为重要的作用。
