Postural Control in Female Rhythmic Gymnasts in Selected Balance Exercises: A Study of Two Cases

“…In rhythmic gymnastics, postural control is trained daily.

Most exercises in rhythmic gymnastics require an above-average ability to maintain balance while standing on a very small support surface; what causes additional difficulty is that the gymnast is required to keep the free leg in different demanding positions and move the apparatus [2].…”
