Electromyographic validation of basic exercises for physical conditioning programmes. I. Analysis of the deltoid muscle (anterior portion) and pectoralis major muscle (clavicular portion) in rowing exercises with middle grip.
The electromyographic activity of the shoulder muscles Deltoid--anterior portion (DA) and Pectoralis major--clavicular portion (PMC) was tested on 24 male volunteers using a 2 channel TECA TE4 electromyograph and Hewlett Packard surface electrodes during the execution of four different modalities of rowing exercises with middle grip. The results showed that rowing exercises are not appropriate for physical fitness programmes for PMC but some of them are significantly useful for DA. The authors present some suggestions to the use of the tested exercises.
