摘要： The effects that different constraints have on the exploratory behavior, measured by the variety and quantity of different responses within a game situation, is of the utmost importance for successful performance in team sports. The aim of this study was to determine how the number of teammates and opponents affects the exploratory behavior of both professional and amateur players in small-sided soccer games. Twenty-two professional (age 25.6 +/- 4.9 years) and 22 amateur (age 23.1 +/- 0.7 years) male soccer players played three small-sided game formats (4 vs. 3, 4 vs. 5, and 4 vs. 7). These trials were video-recorded and a systematic observation instrument was used to notate the actions, which were subsequently analyzed by means of a principal component analysis and the dynamic overlap order parameter (measure to identify the rate and breadth of exploratory behavior on different time scales). Results revealed that a higher the number of opponents required for more frequent ball controls. Moreover, with a higher number of teammates, there were more defensive actions focused on protecting the goal, with more players balancing. In relation to attack, an increase in the number of opponents produced a decrease in passing, driving and controlling actions, while an increase in the number of teammates led to more time being spent in attacking situations. A numerical advantage led to less exploratory behavior, an effect that was especially clear when playing within a team of seven players against four opponents. All teams showed strong effects of the number of teammates on the exploratory behavior when comparing 5 vs 7 or 3 vs 7 teammates. These results seem to be independent of the players' level.

摘要： 红黄牌是足球比赛的裁判指定装备,由英格兰裁判员雅士顿（前国际足协裁判员委员会主席）创立。1970年墨西哥世界杯赛场上,裁判开始使用红黄牌,球员立刻变得规矩起来。苏联球员洛夫切夫成为第一个吃黄牌的选手。4年后在联邦德国世界杯上,智利队的卡斯泽里领到了足球史上的第一张红牌。随着现代足球的发展,红黄牌规则越来越对比赛起到主导作用,同时对规范球场的违规行为,作用至关重要。

摘要： 随着全国校园足球的普遍开展，学校越来越重视足球运动。足球的基本技术包括运球、传球、射门等组合动作，如果教师按照传统的教学模式讲解示范，学生模仿练习，对学生来说兴趣不大，练习积极性也不高。本文利用小垫子体积小、柔软性大等特点，将小垫子进行平放、折叠、人字形竖立等摆放，设计多种多样的练习方法，增加枯燥的足球技术练习的趣味性，学生就会容易接受。这不仅能让学生在玩中练、练中玩，不知不觉地掌握技术动作，还能保持练习的积极性及发展体能和团队合作精神。
