Outline of Final Research Achievements

Effects of the trunk muscle training on the quality of musical vocal performance were investigated using a group of high school students who participated in a chorus group. They were randomly divided into two groups: (a) the training group; (b) the control group. The members of the training group were asked to participate in a course of isometric training which focuses to strengthen the abdominal and back muscles. The course was arranged in a weekly manner and lasted 10 weeks. Effects of the training were investigated in two aspects: (1) efficiency of respiratory function; (2) stability of singing voice by comparing the scores between the pre-, and post- training, both for the training and control groups. Although no significant difference was found between the two groups as to the respiratory functions, some acoustical features, especially, which can be assumed to reflect the stability of "vibrato" provided statistically significant effects of the muscle training.
