Measuring heart rate, breathing rate and skin conductance during exercise

Sensor miniaturization and advances in low power communication protocols have helped enable continuous monitoring of physiological signals. Commercial products exist today which are wearable, in a form of a chest belt or a wrist strap, and can continuously stream or log bio-signals such as heart rate, as well as motion signals. Such devices could be of importance not only to a health-conscious consumer, but also in the healthcare system, for monitoring of patients whose prescribed treatment includes some form of physical activity. This paper proposes a new framework for monitoring compliance and impact of an exercise regimen. While previous related work typically uses an accelerometer based approach, our method gives a more complete picture of impact of exercise on the subject by adding bio-signals such as heart rate, breathing rate and skin conductivity and correlating them with motion signals. Such framework can be used to assess progress over time for different types of exercise regimens.
