This study clarified how the centre of pressure (COP) is kept in the forefoot area during standing on tip toe on one leg by classical ballet dancers. During standing on tip toe on one leg with ballet shoes, the weight is distributed around the first and second toes and at the distal point of the second metatarsal bone ideally. Thus, the supporting surface during standing on tip toe on one leg would be affected by alignment of the metatarsal bones. Motions of the COP during standing on tip toe on one leg were investigated for ten female recreational dancers and six female professional dancers in classical ballet. The results suggested that balance holding time tended to be longer as the distal points of the metatarsal bones aligned more like a straight line in recreational dancers.
