2013年國際身體活動與運動科學研討會專題演講客觀測量身體活動量:當前議題與未來方向

Objective Measurement of Physical Activity: Current Issues and New Directions

摘要


本文旨在探討身體活動測量的議題。首先,簡述客觀身體活動測量的背景,其次探究加速規在身體活動強度切點上的缺失,以及分析傳統的切點模式可能失準的原因等,最後提出加速規測量未來可能的發展方向如:類型辨識與類神經網路等。

並列摘要


This article aimed to examine the issues of measurement of physical activity in children and adolescents. First, it provided a brief introduction to the topic of measurement of physical activity. Then, it focused on the conundrum of intensity-related cut-off points and analyzed the questions- why do cut-off points perform so poorly? Finally, it pointed out new directions in accelerometry regarding pattern recognition and artificial neural network.
