摘要

流行病學研究顯示低身體活動量會提升罹患慢性疾病的風險。身體活動與健康的關聯性有相當的差異性，部分原因為身體活動之不易測量。因此，精確測量身體活動為檢視身體活動水準與介入成效的必備條件。加速度計能夠客觀且精準測量身體活動以及身體活動與健康的關聯性。然而，有關加速度計的選擇與使用仍有許多議題值得討論。本文之目的為針對加速度計測量身體活動進行文獻回顧，探討的內容為加速度計測量身體活動的原理、方法以及效度。

Epidemiological studies have shown that low physical activity is associated with increased risk of several chronic diseases. The relationship between physical activity and health outcomes varies considerably, partly due to the difficulty of assessing physical activity accurately. Accurate measurement of physical activity is a pre-requisite to monitor population physical activity levels and design effective interventions. Accelerometer is an objective and precise technique to adequately assess physical activity and its association with health outcomes. However, there are still some issues related to accelerometer selection and usage. The purpose of this paper is to provide a review of the literature on the general principle, methodological decisions, and validity of accelerometers to assess physical activity.
