The values were normalized through maximum voluntary isometric contraction (MVIC = 100%) and statistically analyzed using the Friedman, DMS and Wilcoxon non-parametric test. A value of p≤0.05 indicated significance (Campos, 1983). All the muscles presented higher electromyographic activity in the return phase of the movement. The triceps brachii was the muscle which had higher activity in both phases of the movement. It was concluded that the front support exercise is efficient for strength development mainly in the triceps brachii muscle.465-471engBiceps brachiiDeltoideusElectromyographyExercisesTriceps brachiiadolescentadultarm exercisebiceps brachii musclecalculationcontrolled studydeltoid muscleelectromyographyFriedman testhumanhuman experimentmalemovement (physiology)muscle isometric contractionmuscle strengthnonparametric testnormal humanstatistical analysisstatistical significancetriceps brachii musclevolunteerAdolescentAdultArmExerciseHumansMaleMuscle ContractionMuscle, SkeletalReference ValuesWeight-BearingArtigoAcesso restrito2-s2.0-0346272805
