Caracterização e comparação do perfil força-velocidade entre atacantes e defensores praticantes de futebol americano de uma equipe de Maceió-AL

Abstract

The present study aimed to characterize and compare the performance parameters that represent the profile Force-Velocity (F-V) between attacking and defending American Football practitioners. 25 American Football practitioners from a team in the city of Maceio - AL were evaluated and divided into two groups (offensive and defensive players). For this, the practitioners were submitted to the single-run sprint test to determine the profile F-V, in addition to the sprint performance parameters. For the profile F-V, the parameters of theoretical maximum horizontal force, theoretical maximum horizontal velocity, force ratio, force difference, and maximal power were estimated. The sprint performance parameters were as follows: peak strength, mean strength, peak speed, mean speed, peak power, and mean power. There was no statistical difference for all parameters of the profile F-V (p > 0.05). Furthermore, there was also no difference in the sprint performance parameters (p > 0.05). In conclusion, the study shows that although American Football practitioners have different roles within the game, the performance parameters derived from the sprint and the profile F-V are not different between attackers and defenders.
