During a back extension roll at Level 4, what is the deduction if the gymnast places their hands on the floor during the squat phase before rolling backward?

When a gymnast performs a back extension roll, a key element of the skill is the fluidity and sequence of movements involved in transitioning from a squat to rolling backward. If a gymnast places their hands on the floor during the squat phase prior to rolling backward, this action is considered a break in the proper form and execution of the skill.

The deduction of 0.30 reflects the level of difficulty in maintaining correct body alignment and control throughout the movement. Placing the hands on the floor indicates a lack of strength and balance, which detracts from the overall execution of the roll. This specific deduction is set to encourage gymnasts to develop the necessary strength and technique to perform the skill without assistance from their hands, promoting proper form and enhancing the aesthetic quality of the routine.
