项目摘要

We developed an instrument to continuously monitor physical activity of the individuals at daily life, and we also developed and implemented an exercise training program for the frail elderly subjects living in the community.1)Development of an instrument to continuously monitor physical activity at daily lifeWith application of both an accelerometer and a barometer, we developed a new instrument to continuously monitor physical activity of the individuals at daily life, named as "Intelligent Calorie Counter : ICC". An accelerometer is designed to be sensitive to three dimension of human movement (vertical-lateral-anteropostal). A borometer is useful in distinguishing whether an individual is moving at flat ground, upward (e.g., ascending the stairs), or downward (e.g., descending the stairs). As compared with conventional instrument for physical activity measurement, this ICC was proved to be more accurate and sensitive.2)Exercise training program for the frail elderly subjects living in the communityThe purpose of this training program was two-fold ; improvement of motor function and promotion of physical activity in daily life. We recruited the frail men and women aged 70 years and over living at the Tsurugaya District of Sendai City. Out of 86 eligible subjects, we randomly allocated 43 subjects into the intervention group and the remaining 43 subjects into the control group. The subjects at the both groups participated in 2-hour session of exercise training once a week for 6 months. The subjects at the intervention group further participated in a lifestyle intervention in which an instructor guided the subjects how to increase their physical activity levels in daily life. The results indicated that, after the intervention, the mean physical activity level increased in the intervention group but decreased in the control group. We would follow up the subjects in order to examine whether the increased physical activity in the intervention group would continue.

我们开发了一种仪器，以连续监测个人在日常生活中的身体活动，我们还开发和实施了一项运动训练计划，为生活在社区的体弱老年受试者。1）开发一种仪器，以连续监测身体活动在日常生活中的加速度计和气压计的应用，我们开发了一种新的仪器来连续监测个人在日常生活中的身体活动，命名为“智能卡路里计数器：ICC”。加速度计被设计为对人体运动的三维（垂直-横向-前邮政）敏感。测辐射计可用于区分个体是否在平地上、向上（例如，上楼梯），或下楼梯（例如，下楼梯）。与传统的体力活动测量仪相比，本ICC具有更高的准确性和灵敏度。2）社区老年体弱者的运动训练计划本训练计划的目的是双重的：改善运动功能和促进日常生活中的体力活动。我们招募了居住在仙台市鹤谷区的70岁以上的体弱男性和女性。在86名符合条件的受试者中，我们将43名受试者随机分配到干预组，其余43名受试者分配到对照组。两组受试者每周进行一次2小时的运动训练，持续6个月。干预组的受试者还参加了生活方式干预，其中指导员指导受试者如何在日常生活中增加身体活动水平。结果表明，干预后，干预组的平均体力活动水平有所提高，而对照组则有所下降。我们将对受试者进行随访，以检查干预组增加的体力活动是否会继续下去。
