Travel describes movement away from the centre of the cross in excess of 50cms
Travel is caused by the Centre of Mass moving horizontally as well as vertically at last contact (LC) This is also referred to as ‘leaning off balance’
Travel can be reduced by developing good core stability, focusing on the spot, the body being straight with the arms up above the head at maximum depression ready for the take off phase from maximum depression (MD) to last contact (LC).
Cast is the term used to describe sideways travel. It is caused by the centre of mass moving sideways as the body leaves the bed. Cast can be corrected by improving the take phase of the skill.
It is common to see casting in a back landing half twist to feet, the roller and cat twist.
Casting may also be combined with travel and gain, so when performing a skill the body may end up landing towards one of the corners of the bed, thus resulting in travel and casting, or gain and cast.
Gain is movement in the opposite direction to the direction of the rotation. (eg) Forward travel in a backward rotating skill or Backward travel in a forward rotating skill.
An example would be landing forwards of the cross in a back landing, or landing behind the cross in a front landing.
Gain can be corrected by working on the position of the centre of mass at take off, gain is usually caused by the hips being pushed forwards or backward, rather than the hips being displaced upwards and forwards or upwards and backwards.
