KERWIN, D.G., YEADON, M.R. and LEE, S-C., 1990. Body configuration in multiple somersault high bar dismounts. Journal of Applied Biomechanics (formerly International Journal of Sport Biomechanics), 6 (2), pp. 147-156.
An 11-segment three-dimensional simulation model was used to modify the
body configurations of eight gymnasts performing multiple somersault dismounts
during the Men's High Bar competition in the 1988 Seoul Olympic
Games. Four layout double somersault performances were modified to change
a characteristic backward arch to a straight body position. This modification
reduced the somersault rotation by 0.03 to 0.10 somersaults. Four tuclced
triple somersault performances were modified so that the thigh abduction angle
was reduced to zero. This modification resulted in underrotations ranging
from 0.01 to 0.34 somersaults depending on the amount of thigh abduction
in the original movement. The additional angular momentum needed for
successful completion of the modified movements was small in general and
in no case greater than 13%.
