Abstract

We examinedr elationshipb etweeno cclusalf orce (OF) andb one mass. A n occlusal-forcem eter (GM 10, Nagano Keiki, Japan) was employed for measurement of OF. Calcaneal bone density was measured by using bonedensitometers(AOS 100, ALOKA, J apan) Physicalc haracteristicws ere also evaluateda nd were comparedw ith OF.<BR>We obtainedf ollowingr esults.<BR>1) Grip strengtho f the large LBM (lean body mass) group (the average LBM; 45. Okg, t he averagea ge; 22.5yrs) was significantlyh igher than that of the low LBM group ( the averageL BM; 34.9kg, the average age; 20. lyrs).<BR>2) Boned ensity of the large LBM group was significantlyh ighert han that of the low LBM.<BR>3) Grip strengtho f the large OF groupw as significantlyla rgert hant hat of the low OF. Thoughw e consideredt hat high OF had beneficiale ffect for high muscularo utput, we also confirmedt hat such phenomenonw as n ot alwaysi n the case.<BR>4) The averageb oned ensityo f the large OF groupw as significantlylo wert han that of the low OF group.<BR>5) Energy expenditure estimated with time study significantly correlated with that estimated with pedometor analysis. Valueso btainedw ith time study were4 00kcal higherin the averaget han that by pedometor analysis.
