With the support of Scientific Research Grant (C)(2) No.13670358,we performed the 4-year periodic measurements of the physical factors on the volunteer subjects of 29 elderlies over 70 years (10 men;19 women) living in the community and 18 elderlies (3 men;15 women) living in the facilities for the aged. These measurements include the followings : basic physical data such as the height, weight, BMI, rate of body fat, vital signs as well as muscular strength of grip and legs, speed of blood stream of A.dorsalis pedis using Doppler ER, bone stiffness of the calcaneus using ultrasonic Achilles, postural sway using Stabilo 101. In addition, we asked questionnaires concerning their experience of the fall and the concomitant bone fracture and their lifestyles on food intake and exercises.During this research period, it was reported that 8 subjects experienced the fall and 11 ones did the bone fracture. Though prominent changes were not noted on the basic physical data for 4 years, the height … More shortened with the age advanced and the rate of body fat tended to increase gradually.1.Concerning the changes of bone stiffness, we presented in the 109^<th> Anatomist Meeting in Fukuoka (2003), the 1^<st> Co medical Meeting of Functional Morphology in Fukuoka (2003), and the 16^<th> Congress of Japanese Society of Nursing Research in Kobe (2003). The weakened muscle strength and the worsened postural sway in the elders was associated with an increased incidence of the fall and bone fracture. It was clearly indicated that the regular exercise was useful not only for keeping enough bone mass but also increase the stiffness.2.Concerning the influence of postural sway and muscular strength of legs to the bone mass, we published in the Journal of Nursing, Shiga University of Medical Science, Vol.3 (2005). hi this paper, the risk factors for the fall and bone fracture were analyzed statistically. The result indicated the stiffness of the fractured group significantly lower than that of a low risk group, but not a clear difference from that of the high risk group. However, the locus of postural sway with eye-closed in women in the fractured group indicated significantly the highest value among three groups. Thus, the risk assessment for the fall and bone fracture might become more useful with a combination of data in the bone stiffness and the postural sway with eye-closed.3.Concerning the blood stream of A.dorsalis pedis, we reported in the 17^<th> Congress of Japanese Society of Nursing Research in Kyoto (2004) and the 2^<nd> Co medical Meeting of Functional Morphology in Otsu (2004). A prominent changes of the blood stream with age was hardly noted in the elders. Less

在国家科学研究基金（C）（2）13670358号的资助下，对29名70岁以上社区老年人（男10人，女19人）和18名70岁以上养老机构老年人（男3人，女15人）进行了为期4年的身体因素定期测量。这些测量包括以下内容：基本物理数据，如身高、体重、BMI、体脂率、生命体征以及握力和腿部肌力，使用多普勒ER测量足背肌的血流速度，使用超声Achilles测量跟骨的骨硬度，使用Stabilo 101测量姿势摇摆。此外，我们还对他们的跌倒和伴随骨折的经历以及他们的饮食和运动生活方式进行了问卷调查，据报道，在本研究期间，8名受试者经历了跌倒，11名骨折。4年来，虽然基本体质指标没有明显变化，但身高、体重 ...更多信息 1.关于骨硬度的变化，我们在2003年福冈第109届<th>解剖学会议、2003年福冈第1<st>届功能形态学联合医学会议和2003<th>年科比日本护理研究会第16届会议上作了报告。老年人的肌力减弱和姿势摇摆恶化与跌倒和骨折的发生率增加有关。2.关于姿势摆动和腿部肌肉力量对骨量的影响，发表在滋贺医科大学护理学杂志第3卷（2005）上。本文对跌倒和骨折的危险因素进行了统计学分析。结果表明，骨折组的刚度显著低于低危组，但与高危组无明显差异。然而，在三组中，骨折组女性的闭眼姿势摇摆的轨迹显示出显著的最高值。3.关于足背肌的血流，我们在<th>京都日本护理研究学会第17届会议（2004）和大津第2<nd>届功能形态学联合医学会议（2004）上进行了报道。老年人的血流变化不明显。少
