Abstract(s)
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.
