How much can be deducted for additional trunk movements to maintain balance on bars during landing?

When evaluating performances on the bars, judges assess the gymnast's ability to maintain balance during landing. Additional trunk movements are considered a deduction as they indicate a loss of control. The appropriate deduction for these additional trunk movements is up to 0.20. This reflects the severity of the impact on the overall execution of the skill. If a gymnast demonstrates excessive upper body movements to regain balance after dismounting, it significantly detracts from the quality of the performance, which is why a 0.20 deduction applies.

Other potential deductions are set for various performance issues, but trunk movements involve a more pronounced error in form and completion, justifying the higher deduction compared to minor form breaks or other less disruptive errors. Understanding the specific deduction structure helps in accurately assessing performances and upholding judging standards in gymnastics.
