신체활동 측정도구 가속도계 Actigraph 고찰 및 소개 = Review and Ontroduction of Physical Activity Assesment Actigraph

다국어 초록 (Multilingual Abstract)

Physical activity means movement of body with skeletal muscle that uses energy. Physical activity plays an important role in health promotion in physical, mental and social dimensions. Generally, exercise prescription is necessary since anyone can do exercise safely and efficiently. First step, physical activity assessment is required for efficient exercise prescription with physical activity assessment devices including physical activity questionnaire, pedometer, heart rate monitor or accelerometer. The purpose of the current study was to introduce and review actigraph. Actigraph, an accelerometer, is a non-invasive device of monitoring human activity. This device consists of a timer to start or stop at specific times and to accumulate values for a specific time frame, a memory to store the resulting values and an interface to download the data from memory. However, there are several limitations in the current version of actigraph such as the inaccurate equation to calculate energy expenditure in a variety levels of exercise intensity, the place to wear and the period time of wearing.
