Abstract


There may be an optimal period of time to maximize the improvement of physical fitness during adolescence. The aim of this study was to examine the magnitude of changes in physical fitness after 8 weeks of preseason training according to chronological ages after the age at peak high velocity. Thirty male young football players from an elite football team (U-16, n= 10; U-17, n= 10; U-18, n= 10) participated in the study. The players completed an 8-week general preseason football training and participated in the pre- and posttests to measure physical fitness. The 8-week preseason training improved the power of all young players (P< 0.05). The 20-m sprint performance was improved by training in U-16 and U-18 (P< 0.05), but no changes were found in the U-17 group (P> 0.05). Significant differences were found in the arrowhead left in U-16 and U-18 (P< 0.05) after training; however, no difference was observed in U-17 (P> 0.05). Coordination was enhanced further in U-16 and U-17 (P< 0.05) compared with that in U-18 (P> 0.05). The performance of repeated sprints and Yo-Yo intermittent recovery test level 1 (Yo-Yo IR1) were similar between pre- and posttraining in all age groups (P> 0.05). Collectively, the results emphasized the importance of systematic and scientific training methods to improve the fitness levels of young football players in the preseason training period. Moreover, training to improve coordination in young football players is effective at younger ages.
