Aiming to realize the application which supports users enjoy walking with an appropriate physical load, we propose a method estimate load and its variation during only available functions of smartphone. Since has linear relationship heart rate, our purpose is rate To this end, build prediction models predict from data including acceleration speed by machine learning. In order track unexpected change focus attention on oxygen uptake similar property devise novel technique GPS so that it used as input model. Moreover, adapt difference among individuals, techniques optimize parameters for each profile-based category normalize absorb individual difference. We applied proposed actual various routes different persons confirmed estimates mean error less than 7 beat per minute.
