The study aimed to investigate the anaerobic performance with laboratory and field tests in youth athletes in different sports. One-hundred four athletes between the ages of 10 and 16, minimum age of training of one year in different sports voluntarily participated in the study. Anthropometric measurements of participants were measured. Wingate Anaerobic Test (WAnT) using Monark cycle ergometer (Monark-Crescent AB, Sweden), Running-based Anaerobic Sprint Test (RAST), and pediatric RAST using photocell advice (Newtest 2000) were performed to determine anaerobic performance. Peak power (PP), average power (AP), minimum power (MP) and fatigue index (FI) were determined for each test. Absolute and relative power outputs, FI, and total exercise time (TED) values of WAnT, RAST, and PRAST were significantly different (p<0.01). The absolute peak, average and minimum power of PRAST were significantly higher than WAnT and RAST. According to test-retest results of WAnT, RAST, and PRAST, ICC 95% CI values have a high-reliability coefficient for all variables. It was found there is a positive correlation statistically between WAnT and RAST for all variables (p<0.01). Besides, there were also positive correlations statistically between WAnT-PRAST and RAST-PRAST excluding fatigue index (p<0.01). As a result of this study, it was determined WAnT, RAST, and PRAST have high reliability and are appropriate for child and adolescent athletes in that age group to evaluate anaerobic performance. Although tests have different motion properties, it was determined they have similar results when performed. High correlations between tests and variables support this determination.
