 note = {The quantitative ultrasound (QUS) method was used to measure the bone mass of the calcaneus among Chugoku Junior College students. The subject numbers and average age were 187 persons and 19.4 years, respectively. The osteosono assessment index (OSI) calculated from the propagation speed of ultrasound (SOS) and transmission index (TI), a self-written history of bone fractures and diet, the number of years since the subject's menarche, and a personal history of exercise of each subject were analyzed and the following results were obtained.
1. A majority of the subjects (32 persons) with a history of bone fractures broke bones in their fingers or hand, between the ages of nine and eleven. There is no significant difference of the bone mass parameters between subjects having bone fracture experience and those not having the experience. No correlation was observed between present bone mass parameters of the subjects and their past experience of bone fractures.
2. The present bone mass of the subjects is not significantly related to any previous dietary restrictions or the number of years since the subject's menarche.
3. The OSl and SOS were positively correlated to the total exercise scores of the subjects. Present bone mass related most intimately to exercise experienced during high school and then to the present exercise-regimen. A multiple regression analysis was conducted using OSI as the dependent variable and the exercise score and BMI (body mass index) as independent variables. The standard regression coefficient is higher between OSI and exercise scores than between OSI and BMI. The results strongly suggest that continuation of exercise after the teens is a very effective way to increase bone mass and to maintain peak bone mass (PBM).},
