However, the Fédération Internationale de Gymnastique Code of Points (COP) was updated after every Olympic Games rendering previous regression models inadequate. Therefore, the objective of this study was to develop a prediction model for vault performance based on judges’ scores. Methods: Handspring vaults (n = 70) were recorded during the Men’s Artistic Gymnastic qualifying round of the 2017 China National Artistic Gymnastics Championship using a video camera placed 50 m perpendicular to the vault table. Kinematic data were coded and correlated with judges’ official competition final scores (FSs). The vault samples were used to develop a mathematical model (n = 65) and to verify the scores against the predicted model (n = 5). Partial least squares regression was established using the statistical software to calibrate and cross validate the model. Results: The goodness-of-fit of a 3-factor model was utilised (R2 cal = 90.13% and R2 val = 87.30%) and a significant and strong relationship was observed between predicted Y (FS) and reference Y (FS) in both the calibration and validation models (rcal = 0.949, rval = 0.932) with Y-calibration error (RMSEC = 0.1727) and Y-prediction error (RMSEP = 0.1990). Maximum height, 2nd-flight-time and DV were the key variables against FS. Using JSPM, 40% of new samples were within the acceptable range. Conclusion: Kinematic variables and known DV seem adequate to form a JSPM that could offer coaches an alternative scientific approach to monitor vault training. 2022-11-01T02:39:28Z 2022-11-01T02:39:28Z 2021 Article Movement, Health & Exercise (MoHE), vol.10(2), 2021, pages 121-127 2231-9409 (printed) 2289-9510 (online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/76666 en Kementerian Pendidikan Tinggi (KPT), Malaysia
