The aim of this study was to investigate the effects of small-sided game training (SSGT) versus conventional aerobic interval training (CAIT) on soccer-specific endurance performance, lactate threshold levels (mmol·L-1), short-passing ability and defensive and offensive skills of a soccer match. Before and after a 6-week training intervention period, eighteen amateur soccer players (age 21.8±4.8 years) were tested. The tests included the anaerobic threshold (AnT) test, the Yo-Yo Intermittent Recovery Test Level 1 (Yo-Yo IR1), and the Loughborough Soccer Passing Test (LSPT). A manual notational match analysis system was utilized to evaluate the defensive and offensive skills of players during the matches. Both the SSGT and CAIT were performed two days a week and consisted of five sets of 6-minute periods of work at the individualized exercise intensity corresponding to the individual anaerobic threshold, with 3-minute of recovery periods between sets. Mann-Whitney U and Wilcoxon signed rank tests were used to examine the between- and within-group differences, respectively. Statistical analyses revealed that the SSGT group players exhibited significantly better in terms of the LSPT scores (p .05). The results of the study suggested that SSGT improved short-passing ability, various soccer skills and physiological parameters, while CAIT only improved physiological parameters. SSGT improves soccer-specific endurance and technical ability of players at the same time, meaning it is a time efficient way of training. Key words: small-sided game, anaerobic threshold training, soccer skills, short-passing ability

小型比赛和常规有氧间歇训练对足球各种生理特征以及防守技巧的影响

这项研究的目的是研究小侧比赛训练（SSGT）与常规有氧间歇训练（CAIT）对足球特定耐力表现，乳酸阈值水平（mmol·L-1），短传能力和足球比赛的防守和进攻技巧。在为期6周的训练干预期前后，对18名业余足球运动员（年龄21.8±4.8岁）进行了测试。这些测试包括无氧阈值（AnT）测试，悠悠球间歇恢复测试1级（Yo-Yo IR1）和拉夫堡足球通过测试（LSPT）。手动记号比赛分析系统用于评估比赛中球员的防守和进攻技巧。SSGT和CAIT均每周进行两天，包括五组6分钟的工作时间，分别对应于个体无氧阈值的个性化运动强度，每组之间有3分钟的恢复时间。Mann-Whitney U和Wilcoxon签署的等级检验分别用于检验组间和组内差异。统计分析表明，SSGT组的运动员在LSPT得分方面表现出明显更好的表现（0.05）。研究结果表明，SSGT改善了短传能力，各种足球技巧和生理参数，而CAIT仅改善了生理参数。SSGT可同时提高球员的足球耐力和技术能力，这是一种省时的训练方法。关键词：小型游戏
