Factors influencing the performance of young football players in the yo-yo intermittent endurance test (Level 2)

摘要

Study aim: To find out whether the ability to accelerate, decelerate and turn may contribute to the performance of young football players during the Yo-Yo Intermittent Endurance Test - Level 2 (YYIEL2).Material and methods: A group of 239 young male football players from three age categories: under 15 years (U15; n = 102), under 17 years (U17; n = 59) and under 19 years (U19; n = 74) were evaluated in sprint, agility, and intermittent exercise performance. Multiple regression models weighted for maturity status were applied.Results: Significant (p2max, such as peripheral limitations and the ability to accelerate, decelerate and turn, may influence the performance during the test.
