In order to improve lifestyle habits and physical fitness in elementary school children and junior high school students, we continuously demonstrated various experimental programs as physical educational activities during 3-5 years. We clarified some behavioral changes from results of the educational interventions. The major findings of the study are summarized in the following two points.1) Multifaceted intervention significantly (p<0.05) improved physical fitness and lifestyle habits (e.g., a decline of TV/game viewing time unidentified complaints) in elementary school children (1st to 6th grade boys and girls). The longitudinal data also revealed that an improvement of eating breakfast habits affects improvement of physical fitness in a lower level group of physical fitness.2) As a result of an experiment for comparing experimental group (four hours of PE class a week) and control class (three hours a week) in junior high school students (1st to 3rd grade boys and girls), an increase rate of physical fitness in the experimental group was higher than the control group in boys (experimental group : 47.8%, control group: 42.3%) and girls (experimental group : 19.9%, control group : 15.2%).
