Introduction: Given the importance of strength training in sports science and rehabilitation, this study compared myoelectric activity of a selected upper limb muscles during performance of the four common training methods to strengthen the selected upper body muscles.
Methodology: 14 power lifters healthy men, with mean age 26±7 years, height 177±5 cm, 81±15 kg weight having at least regular exercise for 3 years, participated in this study. Participants performed four moves ahead and publish forward with a barbell dumbbell shoulder, shoulder pair of dumbbells and dumbbell publishing the run, and surface EMG signals using 16-channel wireless EMG devices made in Italy (Model BTS FREE EMG 300) and with a sampling frequency of 1200 Hz, myoelectric activity of the muscles of the Deltoid, Pectoral and triceps Brachial were collected and analyzed. Each move was 50% of one repetition maximum individual and was repeated 5 times. For statistical analysis of test inserts repeated measures, ANOVA was used. The significance level in this study was considered (p<0.05).
Results: The findings showed that the Pectoral muscle myoelectric activity during the execution of four moves ahead barbell shoulder, shoulder pair of dumbbells, publication and dissemination of the dumbbell dumbbells front, showed a significant difference (p<0.05). But this difference was not significant in the Brachial triceps.
Discussion: It can be released into the dumbbells up to shoulder in front of the barbell to strengthen muscles stating useful for people with injuries. Entries need to do a better proof of the preceding studies further. As well as any moves to strengthen the triceps muscle in the movement of its subsidiary have no priority over the others.
