The aim of this study was to determine the optimal rest period between PAP and medicine ball throwing, and to verify that the performance of the explosive strength of upper limbs was improved when it was preceded by 3×3 90% of 1RM on the incline bench press. Fifteen male respondents (age = 21 ± 1.53; body mass = 73.75 ± 5.18) students of Faculty of Sport and Physical Education, University of Sarajevo, participated in this research. Respondents throw the ball from sitting position, and 3, 5, 7, 10 minutes after the activation stimulus – incline bench press 3×3 90% 1RM. Analyzing the obtained results, an acute increase in the distance of the medicine ball throw was detected. The highest statistically significant pre and post-AP changes occurred in the seventh minute and amounted to 17 cm and 2.89% (p = 0.033). 3×3-90% 1RM IBP results in statistically significant PAP effects and optimal recovery time is 7 minutes.
