In this study, a physical fitness / bone mass measurement test and a questionnaire survey involving 172 5th and 6th grade elementary school students in Tokyo were conducted in order to examine factors related to physical fitness, and the relationship between physical fitness and bone mass. As a result, a large percentage of both male and female children who scored high on the physical test enjoyed physical activity during school holidays, and regularly consumed milk and dairy products. Regarding male students, those who scored high on the physical test frequently engaged in physical exercise or sports, and the prevalence of obesity among them was low. Regarding female students, many of those who scored high on the physical test developed a healthy body image and their average time spent being physically active was longer. In addition, a significant positive correlation was observed between the “maximum oxygen uptake”, the parameter used to determine bone mass and whole-body endurance for both male and female students. The causal relationship of factors related to physical fitness must be examined in the future in order to produce data useful for the prevention of future lifestyle-related diseases and decline in activities of daily living.
