What is the deduction when the body is arched or the hips are open to an extended position with feet over the low bar during the underswing?

When evaluating a gymnast's performance during the underswing on the low bar, a deduction of 0.30 is applied specifically when the body position is not correctly aligned, such as when there is an arch in the back or when the hips are open to an extended position while the feet are over the bar. This is significant because proper form during this skill is essential for a controlled and fluid execution. Maintaining a straight body line, with the hips in the correct position, not only ensures safety but also adheres to the requirements for clean execution in gymnastics.

The severity of the deduction reflects the degree to which the gymnast deviates from the ideal form. A 0.30 deduction highlights a noticeable fault that impacts the overall quality of the routine. Smaller deductions would typically pertain to less significant issues or minor adjustments, while larger deductions would accrue for more severe mistakes. In this case, the open hips and arched body represent a major technical flaw that detracts from the performance and leads to the awarded deduction.
