Efeito de um programa de treinamento baseado no Crossfit Football® sobre as capacidades físicas dos atletas de futebol americano

Abstract

In the United States, American football has a great scientific and technological investment to guarantee the health of the athlete, as well as to improve the physical, technical and tactical performance of its practitioners. American football in Brazil is still very recent, investments are low, and most clubs do not provide adequate physical, technical and tactical training to their athletes. The present study aimed to quantify the effect of 12 weeks of a non-specific and specific training program for crossfit football® on the physical abilities of American football athletes. For this, tests of upper limb strength, speed, agility, and power of lower limbs were performed. These are: Bench Press Test, 40 Yard Desh, Pro Agility Test (5-10-5), Broad Jump Test, and Vertical Jump Test. Eighteen american football players were divided into two groups, 12 players were part of the specific training group (GE, 25.9 ± 5.0 years) and 6 players from the traditional training group (GT, 24.8 ± 5.4 years). Data were submitted to a descriptive analysis (mean and standard deviation). ANOVA Two-Way statistical test (non-parametric - Kruskal-Wallis test) was applied. The results showed significant improvements for the players of the specific training group (GE) in the vertical jump tests (34.92 ± 4.34 cm for 39.90 ± 3.66 cm in height), horizontal jump (227.41 ± 11.20 cm to 246.25 ± 10.10 cm) and Bench Press (15.05 to 19.25 replicates). Significant differences between the groups that performed Specific (GE) and Traditional (GT) training were found in the vertical jump and bench press tests (p <0.05). It can be concluded that 12 weeks of non-specific resistive training (GT) was not enough to cause improvements in the variables evaluated. Specific training has resulted in increases in the power of Lower Limbs and strength of Upper Limbs.
