Drop jump effect over the enhancement post-activation in Colombian high performance athletes

The objective of this research was to study the effects of post- activation potentiation (PAP) on the acceleration of some young Colombian sprinters, in order to propose different training methods, aiming to enhance their performance. Nine athletes from the Colombian national youth team participated in the study. (4 men: age= 16,9 +/- 1.3; body weight 63,0 +/- 6,6kg; height 171,5 +/- 6,6cm; and, 5 women: age 17,1 +/-.4 years old, body weight 63,0 +/- 6,7kg, height 174,2 +/- 8,5cm). Bosco Protocol was applied (Abalakov drop jump and repeat jump in 15s) with the purpose of determining the booster stimulus and also the 30m test with static start pm and post booster stimulus. A t Student test was conducted for samples in relation with a significance of p<.05 to evaluate the effect of the booster stimulus in the results of the Abalalcov test and the 30m acceleration test. The normality in the variable's behavior was proven through the Shapiro Wilk test, applied to samples fewer than 30 individuals. Every single athlete showed signs of improvement after the booster stimulus was applied both in the Abalakov test and the 30m acceleration test; presenting significant differences in the average of the sprinters results in the Abalakov test (p=.000) and the 30rn acceleration test (p= .002) before and after the booster stimulus.
