Throwing in handball is the most decisive action in success or failure in the offensive phases of the game. In order to study and analyse this, it is necessary to measure the throwing speed during the competition. This research aimed to achieve two objectives; the first one, to compare the average throwing speed between the first and the second half of the organized offensive phase during the 2013 Men´s World Handball Championship. The second, to describe the throwing speed between the first and the second half during the 2013 Men´s World Handball Championship with respect to its effectiveness (a goal/not a goal). Throwing speeds were registered in 47 matches in the 2013 World Handball Championship using a radar (StalkerPro S.A., Plano), with a frequency of 100 Hz and a sensitivity of 0.045 m/sec-1, fixed on a tripod behind the goal. Statistical analysis was carried out using SPSS software (version 22). The Kolgomorov-Smirnov test was used to check normality and homogeneity. The results show non-parametric variables. Subsequently, the variables were analysed with the Mann-Whitney U-test. Statistically significant differences were not found in the average throwing speed between the first and the second half of the matches of the World Championship, nor in its throwing effectiveness. These results show that fatigue is not a variable that influences the throwing speeds along a handball match nor the precision/effectiveness in elite male handball.
