Citação: Meijas, J.E.; Cruz, A.M.; Barbosa, Tiago M.

In Congress of the International Society of Biomechanics. Bruxelas
Resumo: The aim was to assess the interaction between kinematics and neuromuscular responses of subjects performing the rowing exercise with barbell in group fitness classes with different external loads and cadences. Fifteen male subjects performed nine sets of nine repetitions of the selected exercise. Sets were composed by a pair wise combination of different external loads (5, 10 and 20 [kg]) and cadences (1, 2 and 4 musical beats) in a randomized order. Kinematical data was collected with an electrogoniometer and it was assessed the: (i) absolute duration of each exercise repetition; (ii) minimum relative angle between the arm and forearm during the flexion action. Neuromuscular data was collected with superficial electromyography and it was computed the EMG amplitude (aEMG), the EMG room mean square (RMS) and the activation time of five muscles from the arm and trunk. Increasing cadence decreased the absolute duration of the exercise cycle. There was no significant interaction between the joint angle and the external load nor the cadence. Increases in the external load and in the cadence imposed a RMS increase as well. It was also verified a significant interaction among the aEMG and the external load in the four muscle groups.
