Aim of these study was to determine the influence of handball resin on accuracy and shot velocity. Survey was conducted among players of the senior team from Handball Club Bedekovčina. Examined sample was based on 17 respondants age of 19,41±3,39, height 182,69±5,41 cm and weight 86,34±13,94 kg. Examinees were tested in 10 tests, among which six of them was aimed to evaluate accuracy and four of them to measure the shot velocity. Based on results of Student's T-test for dependent samples, we can conclude that the handball resin has a statistically significant impact on shot velocity in handball (t= -4,59, p=0,00). Shot velocity was measured in four tests, which of two was without use of handball resin and two with the use of handball resin. In the 9 meter ground shot using resin, the results improved by 10,4% (8,20±7,73) compared to the test of 9 meter ground shot without using resin. In the test of 9 meter jump shot there was an improvement in results in the amount of 13,41% (10,18±2,94) compared to test of 9 meter jump shot without using resin. Results of the Student's t-test for dependent samples in variables for accuracy measuring shows various impact of a handball resin on the performance of different shots. Results of the test for evaluating 9 meter jump shot accuracy show statistically significant difference (t=-2,86, p=0,01). In the test with using resin, the results improved by 73,86% (0.65 ± 0.93) compared to test results without resin. In the results of tests for the evaluation of the accuracy of a shot at the spot from 7 meters and 9 meters ground shot with the use of resin shows a deterioration of the results of 14,55% (0.24 ± 1.09) and 30,7% (0.41 ± 1.50) compared to the results of the same tests without resin but this difference is not statistically significant.
