Which type of movement can result in a deduction of up to 0.3 when judging gymnastics?

Bent knees during a gymnastics routine can certainly lead to a deduction of up to 0.3 points. This type of deduction is significant as judges are trained to look for form and execution in gymnastics performances. When a gymnast performs skills with bent knees, it indicates a lack of control and precision, which are essential qualities in gymnastics. The aesthetic quality of a routine is compromised when the legs are not fully extended, impacting the overall impression of the performance.

While extra steps and large steps on landing also result in deductions, each of these situations has a different range for penalties and is typically assessed differently. Pike down is a specific deduction related to body position during certain elements, reflecting a different kind of skill execution issue. Thus, bent knees consistently represent a clear and widely recognized issue that affects both execution and appearance, justifying the specified deduction.
