Abstract

The aim of this study was to examine acute physiological responses, physical fitness parameters and time-motion characteristics associated with a 4-a-side small-sided game in amateur level players. Sixteen male football players (age 23.9±4.2 years) completed one 4-a-side small-sided game with the aim of maintaining ball possession as long as possible. The participants were monitored for external load and physiological parameters, and tested before and after for physical fitness assessment. A Student’s paired t-test was conducted to determine the differences in physical fitness assessment. A repeated measures analysis of variance (ANOVA), with Bonferroni post-hoc test, was used to determine the dynamics of physiological parameters in players, their RPE and time-motion characteristics of SSG. A significant difference was found in 20 m sprint time between before and after the SSG (Δ=+1.3%) . No significant differences were found between bouts or recovery periods for THb and SmO2, nor between HR-related variables (ES=.005-.383). Compared to RPE in bout 1, greater values were observed in bouts 2, 3, and 4 (Δ=+5.3%, p=.008, ES=.40; Δ=+9.6%, p=.002, ES=.98; Δ=+15.1%, p=.000, ES=1.29; respectively). No significant differences were found between bouts for time-motion characteristics. The results demonstrated that RPE responses increased throughout bout periods, whereas the rest of physiological parameters were maintained over the entire protocol. Due to possible fatigue accumulation, physical fitness performance was impaired (sprint) and the external load was reduced over the course of the protocol.

足球运动员对4场对4场小规模比赛的急性反应

本研究的目的是检测业余水平选手与四人制小边赛相关的生理反应、体能参数和时间运动特征。16名男子足球运动员（年龄23.9±4.2岁）完成了一场四人制的小型比赛，目的是尽可能长时间地保持击球。参与者接受了外部负荷和生理参数的监测，并在身体素质评估前后进行了测试。采用学生配对t检验来确定体能评估的差异。采用Bonferroni事后检验的重复方差分析（ANOVA）来确定运动员的生理参数动态、他们的RPE和SSG的时间运动特征。在SSG前后的20米冲刺时间内发现了显著差异（Δ=+1.3%），HR相关变量之间也没有差异（ES=.005-.383）。与第1轮RPE相比，第2轮、第3轮和第4轮RPE的值更大（分别为Δ=+5.3%，p=.008，ES=.40；Δ=+9.6%，p=0.002，ES=.98；Δ=+15.1%，p=.000，ES=1.29）。前后运动特征之间没有发现显著差异。研究结果表明，RPE反应在整个生育期都有所增加，而其余生理参数在整个生育期间都保持不变。由于可能的疲劳积累，在训练过程中，体能表现受损（短跑），外部负荷减少。

期刊介绍： Kinesiology – International Journal of Fundamental and Applied Kinesiology (print ISSN 1331- 1441, online ISSN 1848-638X) publishes twice a year scientific papers and other written material from kinesiology (a scientific discipline which investigates art and science of human movement; in the meaning and scope close to the idiom “sport sciences”) and other adjacent human sciences focused on sport and exercise, primarily from anthropology (biological and cultural alike), medicine, sociology, psychology, natural sciences and mathematics applied to sport in its broadest sense, history, and others. Contributions of high scientific interest, including also results of theoretical analyses and their practical application in physical education, sport, physical recreation and kinesitherapy, are accepted for publication. The following sections define the scope of the journal: Sport and sports activities, Physical education, Recreation/leisure, Kinesiological anthropology, Training methods, Biology of sport and exercise, Sports medicine and physiology of sport, Biomechanics, History of sport and Book reviews with news.
