The effect of post-activation potentiation on velocity of throws in Lithuanian cadet judo championship medalists

Research object – The effect of post-activation potentiation on velocity of throws. Research subjects – 9 physically active Lithuanian male judo athletes that were medalists in Lithuanian championship in cadets age group (n=9). Age 15,3 ± 0,4 years, weight 73,8 ± 11,5 kg, height 179,3 ± 7 cm. In order to objectively evaluate the results subjects were assigned to groups depending on weight. Athletes weighing from 60 to 66 kg were assigned to the first group, athletes weighing from 79 to 90 kg were assigned to the second group. Objectives of the research: 1. To determine one repetition maximum of all research subjects in deadlift. 2. To identify, how many throws can subjects do in 15 seconds in normal conditions. 3. To identify difference in number of throws done in 15 seconds after post-activation potentiation. Hypothesis – Post-activation potentiation will improve the velocity of judo throws. Conclusion. Heavier athletes produced better results than lighter in deadlift maximal voluntary strength (p<0,01). Strong positive correlation was distinguished between assigned weight group and deadlift one repetition maximum (r= 0,90; p<0,01). In 15 seconds subjects were able to do (6,8 ± 0,4) osoto gari throws. After PAP (post-activation potentiation) they were able to do (7,2 ± 0,4) osoto gari throws. The difference between the number of throws is statistically significant (p
