The study was made to reveal what effects on human body functions had aerobic dance, which was performed in a club of aerobic dance. The lessons in aerobic dance were carried out twice a week for three months. Five subjects, aged 19-31 years old, who participated in the lessons, volunteered in this study. They were all females of healthy medium height and build. Physical characteristics, physical abilities, cardio-respiratory functions were measured before and after the training. A questionnaire about psychological aspects also was investigated as well. The data were evaluated in a similar fashion to the control data measured prior to the training.
　The results were as follows; (1) The physical characteristics after the training varied little from the control except decrease of skinfold fat in some parts. (2) As to the physical abilities, the agility, the flexibility, the balance ability and the general endurance increased after the training. (3) Ventilation capacities, such as forced vital capacity, maximum ventilation volume increased by the training. Moreover, the aerobic ability evaluated by the maximum oxygen intake significantly increased in all subjects after the training. (4) In psychological effects, emotional imbalance and inhibitory disposition tended to be improved by the training.
　It is suggested that aerobic dance conducted twice a week for three months has effects mainly on cardio-respiratory functions and on physical capacities to a certain extent as well as favorable personality changes.
