Investigation of Pre-Season and End-Season Yoyo Performance of Under-16 Players

The aim of this study is to determine whether the U16 age group young players' beginning and end of the season yoyo performances differ according to their positions in the game. Twenty-two athletes (age 15.81 ± 0.39) in the U16 age group participated in the study. Pre-season (before training) and end-of-season (after the last match) tests were applied to the participants. . In the study, the Yo-Yo intermittent recovery level1 (YOYO) test, designed by Bangsbo (1996), was applied. VO2max of the participants was calculated using the formula. In addition, the resting heart rate (CHD) and maximum heart rate (MSD) of the athletes were measured. Shapiro-Wilk test was used to determine whether the data were suitable for normal distribution. Kruskal-Wallis-H test was used for comparison according to the positions. There is no statistically significant difference in Yo-yo, VO2max, DKAH and MKAH values of the players according to their positions. Yoyo, MKAH and VO2MAX scores were significantly different at the end of the season. However, there is no statistically significant difference in end-of-season DKAH values according to their positions. When we compare the Yo-yo, VO2max, DKAH and MKAH values of the players before and after the season, there is a statistically significant difference in all positions. As a result; Yo-Yo, DKAH, MKAH and VO2max differed before and after the season. These differences are thought to reflect the physical and performance characteristics of football. Trainers are advised to plan their training according to these differences.
