1. Introduction Ballet is a physical art form that places major emphasis on aesthetic appearance and movements of the body and is a difficult form of dance in how it challenges the musculoskeletal system [1]. It takes many years to master the skills required to perform ballet, and it is a mixture of low- and high-intensity movements with quick changes in direction over long durations. Dancers must possess the ability to reserve power for explosive jumps but also maintain endurance [2].
