Table 2: Associations between weightlifting performance, front and back squat maximum strength, and CMJ and DSJ force–time metrics for males and females. Figure 2: [PERSON]’s correlation coefficients of the relationships between front and back squat foundation strength exercises, vertical jump force–time metrics, and weightlifting performance. DSJ, deep squat jump; CMJ, countermovement jump; BS, back squat; 1 RM, one-repetition maximum; FS, front squat. Symbols represent the mean, while bars represent the lower and upper 95% confidence interval. Figure 4: Scatterplots with a linear regression analysis of the CMJ height, propulsive net impulse, and peak power force–time metrics for males and females separately. Black circles represent male weightlifters.
