Abstract

This study aimed to describe and determine relationships between repeated sprint and change of direction abilities in football players with cerebral palsy according to four sport classes (FT5 to FT8). Seventeen male football players with cerebral palsy took part in this study (23.0±4.7 years, 65.9±9.5 kg, 168.8±5.9 cm). The repeated sprint ability (6×40-m sprints with a 20-second recovery) was evaluated to determine the best sprint time, mean sprint time, and percentage of sprint decrement. The difference in lactate concentration was determined using blood samples taken three minutes before and after testing. The Illinois Agility Test (IAT) was also used to assess players’ change of direction ability. The FT8 players had better performance (p<.01) in the best sprint time, mean sprint time and in the IAT scores compared to the players of the sport classes FT5/6. Players of the sport class FT7 also reached higher performance in the IAT compared to the players of the sport classes FT5/6 (p<.05). A significant correlation was found between the best sprint time and mean sprint time (r=.94, p<.01), the best sprint time and the IAT (r=.62, p<.01), and between the best sprint time and the difference in lactate concentration (r=-.51, p<.05). The relationships between repeated sprint and change of direction abilities demonstrate the performance profile of para-footballers with cerebral palsy in those variables according to their sport classes, exhibiting lower performance than the values reported for regular football players.Keywords: physical performance, para-sport, brain impairment, Paralympic sport

脑瘫足球运动员重复冲刺与方向改变能力的关系

本研究旨在根据四个运动类别（FT5至FT8）来描述和确定脑瘫足球运动员的重复冲刺和方向改变能力之间的关系。17名脑瘫男足球运动员（23.0±4.7岁，65.9±9.5公斤，168.8±5.9厘米）参加了这项研究。评估重复冲刺能力（6×40-m冲刺，20秒恢复），以确定最佳冲刺时间、平均冲刺时间和冲刺递减百分比。使用测试前后三分钟采集的血液样本测定乳酸浓度的差异。伊利诺伊州敏捷测试（IAT）也被用来评估球员改变方向的能力。与FT5/6级运动员相比，FT8级运动员在最佳冲刺时间、平均冲刺时间和IAT得分方面表现更好（p<0.01）。与FT5/6级运动员相比，FT7级运动员的IAT成绩也更高（p＜0.05）。最佳冲刺时间与平均冲刺时间（r＝.94，p＜0.01）、最佳冲刺时间和IAT（r＝.62，p＜.01）之间存在显著相关性，以及最佳冲刺时间和乳酸浓度差异之间的关系（r=-.51，p<.05）。重复冲刺和改变方向能力之间的关系表明，脑瘫准足球运动员在这些变量中根据其运动类别的表现，表现出低于常规足球运动员的表现。关键词：体能、残疾人运动、脑损伤、残奥会

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.
