Electromyographic validation of the trapezius and serratus anterior muscles in rowing exercises with middle grip

Because the lack of textbooks based on electromyographic studies in the area of exercises for physical conditioning, the authors proposed to study the trapezius (upper portion) (TS) and the serratus anterior (lower portion) (SI) muscles during the execution of four different modalities of rowing exercises with middle grip in 24 male volunteers, 18 to 25 years old. 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.
