The purpose of the study is to give information to gymnasts and coaches for improving athletic performance and about the possibility of medals on Floor Exercise final in Olympics Game(OG) and World Championship(WC). The professional gymnastics study for the floor exercise difficulty score has compared the difficulty value (DV) and the connection value(CV) and have made changes to the code of trend skills. The OG athletes believe that the acro A element is 22% higher, the E element is 13% higher, and the G element is 2% lower than the standard. On the other hand, the WC athletes believe that the A element is 21% higher, the D and E element is 11% higher, and the H element is 5% lower than the standard. As a result, the OG compared to the WC see that the DV is lower and the difficult score is higher. The OG athletes view that the dance A element is 11% is lower, C element is 12%, and the D element is 13% is higher. The WC athletes see that the C element is 15% higher and the E element is 13% higher. In the overall analysis, the CV for the OG is 0.40 ± 0.19, and the WC is 0.14 ± 0.12. The OG have a result of 60% in the acro element and a 40% in the dance element, whereas the WC have a 61% in the acro element and a 41% in the dance element that shows no difference. However, with the new emergence of the higher I element, the double salto bwd tucked with a 720°(5.702) was in the G element and has been put into the H element. The acro element has increased no matter what.
