The relationship between performance in physical tests and the match intensity from the heart rate (HR) response has not been studied in soccer. Thus, this study aimed to verify the correlation between the performance in physical tests and the intensity of the soccer match. Eleven Under-20 soccer players from the first division were evaluated in 2 official matches. The Yo-Yo intermittent aerobic test level 1 (YYIR1), 10-m and 30-m speed, repeated sprints ability (RSA, 6 x 20-20 m), the squat (SJ) and countermovement (CMJ) jump tests were performed. The heart rate (HR) was used to calculate the impulse training (M-TRIMP) by Edwards’s methods, and the time spent above 90% of HRmax (HR>90%) was considered a high-intensity parameter. Pearson's correlation was applied, considering the significance level of p < 0.05. Significant correlations occurred between YYIR1 and M-TRIMP (r = 0.72) and the time in HR>90% (r = 0.51) and between the best time in RSA (RSAbest) and HR>90% (r = -0.50). YYIR1 was the best test related to the match intensity measured by the HR. RSAbest was also a good high-intensity indicator of the match, while jump and speed tests were not.
