At the 1988 Seoul Olympic Games, eight full twisting somersault dismounts
from the high bar were filmed using two cameras during the compulsory exercises
of the Men's High Bar competition. Angles describing body configuration
and orientation were determined and were input into a computer
simulation model of aerial movement. The deviations between simulation and
film were less than 2.5° for tilt angles and less than 0.07 revolutions for twist
angles. The twisting techniques employed were quantified using the tilt angle
as a measure of twisting potential. Contributions to the maximum tilt angle
were determined using simulations based on modifications of the film data.
Each of the eight competitors obtained most of the tilt using aerial rather
than contact techniques. In general, the majority of the aerial contributions
arose from asymmetrical arm and hip movements.
