A system and method, capable of analyzing a body movement by using time-series data, other than a body movement, obtained continuously by a sensor for measuring biological information. A body movement analysis system comprising a measuring means for measuring continuously biological information from a body to obtain time-series data, and an extracting means for extracting, as body movement waveform data, a low-frequency component having a frequency up to a specified frequency from the time-series data; and a body movement analysis method performed by using this body movement analysis system and having a measuring step and an extracting step. Time-series data obtained by continuously measuring biological information from a body contains a low frequency component generated from a body movement. The low frequency component had to be eliminated as noise in the past. The body movement analysis system and the body movement analysis method can provide body movement-indicating body movement waveform data by extracting a low-frequency component having a frequency up to a specified frequency from the time-series data.
