In the paper, titled "Hierarchical factor structure of muscle strength", hierarchical factor solution was applied to 8 X 8 correlation matrix, which was composed of correlation coefficients between strength variables, and one general factor ; named as general strength factor, and four second order factors; two of them named grip strength factor and factor of limbs, shoulder girdle and back strength, respectively. The characteristics of these factors are quite different from the factors extracted by ordinary orthogonal solutions, hence, it is very important to specify them. Thus, in this paper, the measurement of those factors was discussed. As for the measurement, the complete measurement method is extremely hard to be applied because it includes various complicated computations. Therefore, the short method, which was developed by W. Lederman 1939, was applied. Then, the general strength factor can be estimated with all variables at multiple correlation coefficient; 0.9297, and also the grip strength factor can be estimated with all variables at multiple correlation coefficient; 0.8035, factor of limbs, shoulder girdle, and back strength at 0.7978. It is not so practical to use all variables to estimate each factor score. Then, the author attempted to decrease the number of variables for estimation. For instance, it was found that the general strength factor can be estimated with grip strength (right hand), back strength and leg strength at multiple correlation; 0.745, and also with grip strength (right) and back strength at 0.672. These discussions are carried to all factors extracted.
