- Abstract
The aim of this study was to compare the maximum load in the 1 RM (maximum repetition) test realized of lat pull-down exercise with open pronated handgrip (OPG) and close supinated grip (CSG) and to compare the electromyography activity of biceps brachii and latissimus dorsi muscles in these exercises. Ten male subjects practicing of weightlifting (24.83 ± 2.32 years) took part of this study. The 1 RM test protocol and electromyography activity (% RMS) of biceps brachii and latissimus dorsi were evaluated in two exercises. The t-test and analysis of variance for repeated measures were used and the level of significance was set at 5%. Significant difference was found between two handgrips (p<0.05), with higher values in the CSG. Significant difference was found only in the latissimus dorsi muscle between two handgrips (p <0.05), with higher values in the OPG. We conclude that in the CSG can be used higher load when compared with OPG; electromyography activity was greater in the lat pull-down exercise with the OPG only for the latissimus dorsi muscle, without difference in the biceps brachii.
