Validação de uma equação de estimativa da força máxima no exercício agachamento em atletas universitários

Abstract

The purpose of this study was to compare the results of a 1-RM estimation equation using percentages of body mass with 1-RM determined through the traditional protocol in university athletes. Forty-seven male and female university athletes participated in the study; handball (n = 19, age 23.6 ± 4.1 years, height 170.0 ± 0.1 cm and body mass 78.5 ± 17.9 kg); basketball (n = 12, age 21.2 ± 2.6 years, height 170 ± 0.1 cm and body mass 75.0 ± 11.7 kg), soccer (n = 06, age 19.8 ± 3.1 years, height 170 ± 0.0 cm and body mass 66.2 ± 2.2 kg), futsal (n = 07, age 22.7 ± 3.6, height 170 ± 0.1 cm, and body mass 68, 2 ± 18.3 kg) and volleyball (n = 02, age 19.5 ± 3.5 years, height 176 ± 0.1 cm and body weight 72.6 ± 5.8 kg). They underwent two visits with a 48-hour interval, and in the first one they performed adapted warm-up and the traditional 1-RM protocol, during the second visit they performed a specific warm-up with 50% of the value found in the traditional 1-RM test and the power test with two attempts for three body percentages (80, 100 and 120% of body mass). Athletes of various sporting modalities did not present differences in the relation between maximum strength and body mass. There was no significant difference between the real 1-RM and the 1-RM estimated through 80%, 100% and 120% of the body mass, it was verified that the use of the mean value of the 2 repetitions with 120% of the body mass presented a higher correlation with the real 1-RM.
