Features of the use of asymmetric dumbbells when performing strength exercises

The subject of this article is the analysis of differences in shoulder girdle muscles' electrical activities of various disciplines sportsmen during exercises with symmetric and asymmetric dumbbells. It has been found, that in most cases the maximum amplitude of electromyograms and, consequently, the muscular effort, are significantly different, which allows to increase impact selectivity of muscle-strengthening exercises with dumbbells on sportsmen muscles.
