These were compared with the action potential level determined for the same muscles by four different modalities of execution of the frontal-lateral cross, dumbbells exercises. Twenty-four male volunteers were examined using a 2 channel TECA TE4 electromyograph and Hewlett Packard surface electrodes. The statistic analysis showed significant (p<0,05) superiority for all the frontal-lateral cross, dumbbells exercises in comparison to all rowing exercises for the PMC, for the DA this generalized supremacy was not observed.75-79engElectromyographyExercisesM. deltoidM. pectoralis majorPhysical conditioningadolescentadultclaviclecomparative studycontrolled studydeltoid muscleelectrodeelectromyographygrip strengthhumanhuman experimentmalemuscle action potentialmuscle contractionmuscle exercisenormal humanpectoralis major musclephysical capacityshoulderstatistical analysisvalidation processaction potentialarmexercisefitnesshand gripphysiologyreference valuereproducibilityskeletal muscleweight liftingAction PotentialsAdolescentAdultArmExerciseHand StrengthHumansMaleMuscle ContractionMuscle, SkeletalPectoralis MusclesPhysical FitnessReference ValuesReproducibility of ResultsShoulderWeight LiftingArtigoAcesso restrito2-s2.0-170444481503744976017847328
