Dancers are highly trained athletes who are at significant risk of injury due to the repetitive nature of their movement patterns. Most ballet injuries result from overuse and occur in the lower limbs. Therefore, the behavior of the lower limbs during a basic ballet movement should be studied in order to identify and subsequently correct mechanical factors that may contribute to injuries. This study analyzed a cou-de-pied derrière with demi-plié to piqué arabesque gesture executed by 18 ballet dancers identified in two groups: experienced dancers (EDs) and beginner dancers (BDs). Kinematic, baropodometric, and electromyographic analyses enabled the observation of differences between these study groups with regard to joint angles, velocities, foot pressure behavior, and muscle activation during execution of the gesture. Experienced dancers reached greater hip and lumbar spine hyperextension and demonstrated less forward torso flexion, which enables better execution of the gesture compared to BDs. The highest foot pressure in both groups was found in the first metatarsal, with a tendency toward the great toe. In terms of muscular activation, BDs exhibited lower electrical activity than EDs. It is concluded that: 1. ankle and knee angles in demi-plié are not defined by dancers' expertise; 2. the faster the leg is raised during piqué-arabesque the better the gesture; 3. special attention to the metatarsal heads is required due to the high pressures found in this study; and 4. activation of different muscle groups depends on the complexity of the gesture and dancer's expertise.
