This study was planned to compare the Bone mass of KENDO aged men with that of normal aged controls to make clear the effects on the long term practice of KENDO. The subjects were 21 KENDO aged men (KENDO aged group),19 normal similar aged men (Control group), and 8 KENDO young men (KENDO young group). They had average ages of 68.9 years,66.9 years, and 30.4 years. Measurements were made using an Achilles Ultrasound Bone Densitometer (Lunar corp.Madison WI). We measured velocity (SOS; speed of sound), attenuation slope (BUA; broadhand ultrasound attenuation), Stiffness (calculated from the combined data of SOS and BUA), and Osteoporotic centile in the os calcis. Mean values of SOS, BUA, and Stiffness in KENDO aged group was significantly (p<0.001) higher than in control group.Osteoporotic centile in KENDO aged group was significantly (p <0.001) lower than in control group.And, the difference between right and left had no signifficant in both group.These results suggest that regular long term KENDO practice is effective for the maintenance of bone mass
