Twisting techniques used in freestyle aerial skiing
At the 1988 Calgary Winter Olympics, six triple somersaults with three twists
or four twists were filmed using two cameras. Angles describing body configuration
and orientation were determined and were used as input into a
computer simulation model of aerial movement. It was found that the twist
angle of each simulation deviated from the corresponding angie obtained fTom
film hy less than 0.08 revolutions during the first somersault of each movement.
Contributions to the tilt angle after one somersault were determined
using simulations based on modifications ofthe film data. It was found that
of the six competitors, two initiated the twist during the takeoff phase, two
initiated the twist during the aerial phase, and two used a combination of
both methods.
