Abstract

We aim to investigate the differences in physiological characterization between Yo-Yo intermittent recovery test level 1 (Yo-Yo IR1) and level 2 (Yo-Yo IR2) in Japanese college soccer players. Eighty-two Japanese college soccer players (elite, n=40; non-elite, n=42) participated in the study. All subjects took part in three tests Yo-Yo IR1, Yo-Yo IR2, and laboratory treadmill tests. The order of the three tests was randomized across subjects. The Yo-Yo IR1 test was not significantly different between elite (2369.0±319.2 m) and non-elite (2315.2±346.3 m) players. In contrast, the Yo-Yo IR2 test was significantly different between elite (1035.0±147.5 m) and non-elite (919.0±119.3 m) players. Anaerobic threshold (AT) was significantly correlated with both Yo-Yo IR1 and Yo-Yo IR2, although the correlation was stronger for Yo-Yo IR2. Our findings suggest that the Yo-Yo IR2 test will probably be a better tool than Yo-Yo IR1 in measuring endurance capacity in Japanese college soccer players.

日本大学生足球运动员溜溜球间歇恢复测试1级与2级生理特征的差异

本研究旨在探讨日本大学足球运动员悠悠球间歇恢复测试第一级(悠悠球IR1)和第二级(悠悠球IR2)在生理特征上的差异。日本大学足球运动员82名(精英，n=40;非精英(n=42)参与了研究。所有受试者都参加了三个测试:溜溜球IR1、溜溜球IR2和实验室跑步机测试。三个测试的顺序是随机的。优秀选手(2369.0±319.2米)和非优秀选手(2315.2±346.3米)之间的溜溜球IR1测试差异无统计学意义。相比之下，优秀运动员(1035.0±147.5 m)和非优秀运动员(919.0±119.3 m)之间的溜溜球IR2测试差异显著。无氧阈值(AT)与溜溜球IR1和溜溜球IR2均有显著相关，但溜溜球IR2的相关性更强。我们的研究结果表明，在测量日本大学足球运动员的耐力能力方面，溜溜球IR2测试可能比溜溜球IR1测试更好。
