ABSTRACT
The practice of a physical activity is fundamental in the context of health and well-being. Badminton is one of the most practiced racquet sports, belonging to the group with great speed in handling the racquet. The analysis of muscle activity contribution to the performance of the movement associated with this sport becomes essential for a better understanding. The present study aimed to evaluate the muscle activity of the arm, bicep, and triceps muscles associated with the smash movement, considering two types of rackets with different stiffness. A group of 6 volunteers, with a mean age of 21.8 (± 4.5) years, and an average badminton practice time of 10.7 (± 5.3) years, performs 10 valid repetitions of the movement and the muscle activity was collected using surface electromyography. The analysis of the results shows that the most rigid racket shows a greater muscular activity of the bicep and the lateral head of the triceps.
