The main motivation of this study is to establish an ambulatory cardio-respiratory analysis system for the monitoring and
evaluation of exercise and regular daily physical activity. We explored the estimation of oxygen uptake by using noninvasive
portable sensors. These sensors are easy to use but may suffer from malfunctions under free living environments. A promising
solution is to combine sensors with different measuring mechanisms to improve both reliability and accuracy of the estimation
results. For this purpose, we selected a wireless heart rate sensor and a tri-axial accelerometer to form a complementary
sensor platform. We analyzed the relationship between oxygen uptake measured by gas analysis and data collected from the simple
portable sensors using multivariable nonlinear modeling approaches. It was observed that the resulting nonlinear multivariable
model could not only achieve a better estimate compared with single input single output models, but also had greater potential
to improve reliability. |
