The development of a device is reported called the Large-scale integrated Motor Activity Monitor to examine physical activity during individuals' normal daily lives. The unit which is slightly larger than a wrist watch records body movement when worn at various body locations. Two population studies were conducted to evaluate the units. Experiment 1 examined 20 male graduate students for a two-day period. The data indicated that the units were sensitive to individual differences in physical activity and did not interfere with normal activities. Experiment 2 compared 10 Physical Education majors with 10 non-Physical Education majors by having individuals log activities and record movement counts for a two-day period. The movement data revealed that the monitors significantly discriminated between the two populations. The energy expenditure derived from the specific loggings was highly related (r = +.69) to the trunk movements, indicating that the movement counts are an accurate estimate of physical activity. The high relationship to energy analysis, the sensitivity of the units and the ease of implementation indicate that the units may be useful in relating normal activity to acute heart disease and to risk factors such as obesity and lipoproteins.
据报道，一种名为大规模集成运动活动监测器的设备已研发出来，用于在个体日常生活期间检测身体活动。该设备比手表稍大，佩戴在身体的不同部位时可记录身体运动。进行了两项群体研究以评估该设备。实验1对20名男性研究生进行了为期两天的检测。数据表明，该设备对身体活动的个体差异敏感，且不干扰正常活动。实验2通过让个体记录活动并在两天内记录运动计数，将10名体育专业学生与10名非体育专业学生进行了比较。运动数据显示，监测器能显著区分这两个人群。从特定记录中得出的能量消耗与躯干运动高度相关（r = +0.69），表明运动计数是身体活动的准确估计。与能量分析的高度相关性、设备的敏感性以及实施的简便性表明，该设备可能有助于将正常活动与急性心脏病以及肥胖和脂蛋白等风险因素联系起来。
