ABSTRACT

Purpose: Determining the acute effect of a Complex Training in bench press over grenade throwing in professional and amateur military pentathletes.
Methods: Nineteen military pentathletes divided into two groups were part of the study (Professional Group = 10 and Amateur Group = 9). Variables measured were: Distance maximum in grenade throwing and peak power in bench press. Complex Training protocol consisted of: 4 sets of 5 repetitions at 30 % of one repetition maximum + 4 repetitions at 60 % of one repetition maximum + 3 grenade throws with a 15-second rest. For the statistical analysis, repeated measures ANOVA was used, the effect size was estimated with Eta Partial Squared.
Results: Distance maximum of grenade throwing showed a significant increase between the Control Set and the four experimental sets for the Professional Group (p = 0.0019, effect size = 0.370) and a significant decrease in the Amateur Group (p = 0.0128, effect size = 0.305); peak power in bench press did not suffer significant modifications in both groups (Professional Groupp = 0.15, effect size = 0.166; Amateur Group p = 0.17, effect size = 0.199).
Conclusions: The results of the study showed a positive acute effect from Complex Training on the distance of grenade throwing only for professional military pentathletes, such effect was attributed to a Post-Activation Potentiation of the muscles involved in throwing. The significant decline in grenade throwing observed in the amateur military pentathletes was attributed to the impossibility of synthetizing ATP post-workout.
