For the recordings, it was used a two-channel TECA TE 4 electromyograph and Hewlett Packard surface electrodes. For the movements, a supine bench and a 120 cm-long bar made of low weight wood were used. The results showed that TS acted significantly in upright, sitting and inclined rowing, justifying its inclusion in physical conditioning programmes, while SI, in spite of acting preferentially in upright and sitting rowing, presented activity levels which do not justify its inclusion.403-411engadultanalytical parametersbody positionbookconditioningelectrodeelectromyogramelectromyographyequipmentexercisehand griphumanhuman experimentmalemedical literaturemusclemuscle contractionmuscle functionnormal humanserratus anterior musclesittingstandingtrapezius musclevalidation processAction PotentialsAdolescentAdultArmElectromyographyExerciseHand StrengthHumansMaleMuscle, SkeletalPhysical FitnessReference ValuesReproducibility of ResultsShoulderArtigoAcesso restrito2-s2.0-00367908593744976017847328
