Quantitative Analysis of Training Goal Setting in Goal Orientation: A Case Study of Athletes on the National Men's Weightlifting Team

Goal orientation has been proven to effectively promote and enhance athletic performance. However, methods of goal setting exhibit certain biases in describing the development of athletic performance, and the formulation of goal orientation has not been closely integrated with the characteristics of specific sports. The study employed the quantitative data analysis, with male athletes of the 102 kg category from the Chinese national weightlifting team, who participated in the 2024 Paris Olympic Games. Specific indicators and characteristic values of weightlifting were calculated and analyzed, focusing on the relationship between barbell weight and concentric peak velocity. The concentric peak velocity under maximal weight attempts was predicted and used as an anchor point for goal setting, thereby assisting athletes in completing goal-oriented training tasks. Under the conditions of both snatch completion and barbell lift, the linear model (snatch completion: t=8.25, P<0.01; barbell lift: t=11.70, P<0.01) and nonlinear model (snatch completion: t=43.51, P<0.001; barbell lift: t=42.93, P<0.001) of the relationship between barbell weight and concentric peak velocity were statistically significant. Determination coefficients of equations demonstrated significance in both the linear model (snatch completion: R²=0.75, P<0.01; barbell lift: R²=0.78, P<0.01) and nonlinear model (snatch completion: R²=0.91, P<0.001; barbell lift: R²=0.97, P<0.001). The results indicated that independent variables had a strong explanatory power for the dependent variables. By introducing quantitative analysis into the goal setting process, the present study explored the relationships between athletic performance variables, revealed the development patterns of athletic performance and provided sufficient digital support for goal orientation training.
