The aim of the present study is to develop an advanced method for estimating the Hill's characteristic equation between force and velocity and to apply to detemination of the muscle force indices such as the maximal isometric force and maximal power. The estimation was performed according to the following procedures: 1) transforming the characteristic function to a linear form, 2) estimating the maximal isometric force providing the regression line with the maximal correlation coefficient using dynamic muscle force and velocity measured, 3) determining heat and energy liberation constant in the characteristic equation, which were obtained from the intercept of y-axis and slope of the regression line. In addition, the non-linear optimization was utilized for further improvement of the accuracy. In this meaning, the method is referred to as the Maximal Correlation Method. The theoretical validity of the estimation method was confirmed by the statistical simulation with a number of samples (10, 000 samples) from Gaussian random population. The statistical simulation and experimental results suggest that seven samples is the least number that allows accurate estimation of the muscle force indices with the estimation error of less than 10%. The present method appears to be a useful tool in investigating human dynamic movement.
