A significant effect of anthropometric variables on the muscle torque measured in the knee joint was demonstrated. A regression model with four anthropometric variables estimating the biomechanical values was statistically significant, and all predictors explained 38% of the torque variation in the knee extensors and 25% of the torque variation in the knee flexors. Three of the four predictors in the model had a significant effect on the torque of the knee extensors and flexors.
