What is considered an excessive bend in arms for which the maximum deduction is applied in vault support?

The maximum deduction for an excessive bend in the arms during vault support is applied when the arms are bent 90 degrees or more. This is because a significant bend compromises the gymnast's ability to maintain proper form and stability while executing the vault. In gymnastics, maintaining straight arms during the support phase is crucial for optimal performance and safe landing. When the arms are bent to this degree, it signals a lack of strength or control in the gymnast's execution of the vault, leading to the maximum penalty as defined by judging guidelines. Deductions for arm bends help ensure that gymnasts adhere to the technique standards set by the governing body of gymnastics.
