Wheelchair Basketball (WB) follows almost the same rules as Conventional Basketball (CB). Objective: Evaluate the electromyographic (EMG) activation of the pectoralis major (PM), anterior deltoid (AD), and triceps brachii (TB) muscles during shooting in CB and WB athletes and to verify whether there is any difference in muscle activation between the categories. Method: Comparing two groups in a transversal study, CB and WB, in which eleven individuals submitted to an electromyographic examination, of muscles PM, AD, TB on the extremity that was doing the shooting. We used a 4-channel EMG (Miotec/Brazil) (2000Hz/channel). Results: Comparing the muscles, the CB group showed a significant difference: greater AD muscle activation compared to the others; however in the WB group, no differences were found. When comparing between the groups, the PM muscle showed greater activation in the WB group, while the AD muscle was more active in the CB group. The TB muscle showed no difference between groups. Conclusion: From these results, the athletes from the CB and WB groups showed differences in muscle activation during shooting. However, both groups activated the AD the most, followed by the TB. The least active muscle was the PM, and these differences were more visible in the CB group.
