Which angle signifies an 'insufficient stretch' in a vault?

The angle that signifies an 'insufficient stretch' in a vault is indicated by an angle between 91 and 135 degrees. In gymnastics, particularly in vaulting, achieving proper body position and angles during execution is crucial for evaluating the performance quality. When a gymnast demonstrates an insufficient stretch, it typically means their body has not fully extended into the desired straight position that is expected at the peak of the vault.

In this context, if the angle is within the range of 91 to 135 degrees, it suggests that the gymnast's body position lacks the full extension required for an optimal vault. Proper form includes achieving a straight and elongated position, and any deviation from this is reflected in the angles being referenced. If the angle is less than 90 degrees, for instance, it might indicate a more acute position which can signify a different issue altogether. An angle equal to 180 degrees would imply a completely straight body, and anything greater than 180 degrees would suggest a level of overextension or a different type of error.

Thus, recognizing the appropriate angle that denotes insufficient stretch aids judges in assessing the execution quality and determining deductions in the scoring process for the athlete's performance.
