Beforehand, in the measurement of flexibility, part 1, Japanese Journal of Hygiene, Vol.20, NO.2, 1965, the author investigated the distance-method and angular-method analytically, and studied comparatively on the factors that influence both measures obtained by distance-method and angular-method.In this study, the angular-method is compared with the distance-method in reliability using the analysis of variance and also the objectivity of angular-method is investigated. Furthermore, the valid number of repetition of measurement, accepting measure and measurement error are investigated. Therefore, the author reports the findings through these investigations.1) For reliability, the angular-method held R=.8943 and the distance-method R=.7948, where R stands for reliability coefficient. Then, it can be said that the angular-method is more reliable than the distance-method.2) The investigations on objectivity of Trunk flexion, Extension, Sideward bend measurements concluded that the variance due to different testers was not significant. Therefore, it can be concluded that their objectivities are satisfactory.3) With both angular and distance-method, the dispersion of measure due to ten repetitions of measurement is significant at the significant level, .01 and .05.4) The dispersion of measure due to not more than five repetitions of measurement, for angular-method, and the one of measure due to not more than three repetitions of measurement, for distance-method come to be not significant. That is, the dispersion of measure due to more than five repetitions, for angular-method, and more than three repetitions, for distance-method, was found significant. Then, the valid number of repetition of measurement was found out.5) For the angular-method, correlations between the mean of five-times-repeated measurements and mean, maximum, minimum, first measure which are taken from three-times-repeated measurements were computed. They were found considerably high; r=.9981, r=.9925, r=.9803 and r=.9871, respectively.6) Furthermore, the correlations between mean of three-times-repeated measurements and the measure of each time are considerably high; r=.9894 with the first measure, .9935 with the second, .9931 with the third.
