Exercises Intensity Estimation Based on the Physical Activities Healthcare System

The suitable and personalize physical activities plan is a consequential and rewarding strategy to improve individual´s health and keep his/her fitness. In this paper, a physical activities healthcare system (PATHS) based on the wearable wireless sensor unit is proposed to help persons evaluate the exercise intensity and estimate the caloric expenditure with electrocardiogram and motion sensors. The proposed system is useful for quantitative estimation of physical activities and helpful in monitoring progress of an individual´s exercise program. Experiments based on the prototype system show that our system can estimate the exercises intensity and the caloric expenditure easily and conveniently.
