Abstract
Introduction: The dancers must have the necessary strength qualities to complete the dance movement tech-niques and coordinate the body movements, besides giving full capacity of execution to the qualities such as muscular strength, explosive power, and control in accelerated movement. Objective: Verify the main muscular morphology of the lower limbs of sports dancers. Methods: 24 undergraduate students were selected from a sports school of a university, specialized in sports dance, and divided into three groups for a physical fitness experiment. Results: Different training pressures responded with different effects on the thickness of major lower limb muscles. Compared to the thickness of the rectus femoris in the resting state before the experiment, muscle thickness immediately after exercise was significantly increased in the 250 and 300 groups (P<0.05). Conclusion: Training at a moderate pressure level - pres-sure value of 200 mmHg to 250 mmHg -can achieve better results. The presented protocol resulted in a functional improvement of the skeletal muscle. Level of evidence II; Therapeutic studies -investigation of treatment outcomes.
