RT Journal Article T1 Longitudinal Study of Individual Exercises in Elite Rhythmic Gymnastics A1 Sierra Palmeiro, Elena A1 Bobo Arce, Marta A1 Pérez Ferreirós, Alexandra A1 Fernández Villarino, Maria De Los Angeles K1 6399 Otras Especialidades Sociológicas AB The performance evolution in rhythmic gymnastics depends on changes in code ofpoints. At the beginning of each Olympic cycle the code of points changes and therefore,the content of the competition exercises, as well. This study aimed to analyze – foreach apparatus – the evolution of number of technical elements and final score overthe last two decades (last 13 world championships), how they have been affected bychanged code of points, and how the final score relates to the number of technicalelements performed. The sample consisted of 416 exercises in five apparatus: ball (96),rope (40), hoop (96), ribbon (88), and clubs (96). The following variables were gathered:code of points, apparatus, technical group, total number of elements, final classification,and final score. Linear mixed-effects models were used to examine the effects onthe number of elements and final score in each apparatus. The number of technicalelements increased in all apparatus, between 7.4 and 20% over a 10-year period. Therewere mixed evolutions of final score between the different apparatus, between −6.3 and14% over a 10-year period. There is small increase in number of elements in hoop anda small decrease in rope after a code change. There was a small decrease in final scorein championships after a code change in hoop, moderate in clubs and ribbon, and largein rope. There was a negative relationship between number of elements performed andfinal score in clubs. In conclusion, the code change generally effects the final scorenegatively, but there were apparatus specific effects of code change on number ofelements and relationship between number of elements and final score PB Frontiers in Psychology SN 16641078 YR 2019 FD 2019-06-28 LK http://hdl.handle.net/11093/7938 UL http://hdl.handle.net/11093/7938 LA eng NO Frontiers in Psychology, 10(1496): 1-7 (2019) DS Investigo RD 14-feb-2025
