Values are mean ± SD; MV: mean velocity; MPV: mean propulsive velocity, PV: peak velocity; General: data obtained from general equations; Individual: data obtained from individual equations; 1RM: one-repetition maximum; ES: effect size compared to actual 1RM values; 90%CI: 90% confidence interval; SEE: standard error of estimation; Pearson correlation, slope and intercept values were obtained from relationships between actual and predicted 1RM data. Significant differences compared to actual 1RM values:* p < 0.05;** p < 0.001.
