Abstract
The use of accelerometers for the assessment of daily physical activity looks promising. This method based on a demonstrated relationship between energy expenditure due to physical activity and acceleration measured on the human body. A triaxial accelerometer based on three uniaxial piezoresistive accelerometers, was developed to evaluate the relationship between accelerometry and energy expenditure during sedentary activities and walking. Special attention was paid to the analysis of unidirectional and three-directional accelerometer output. It was concluded that the sum of the integrals of absolute acceleration from the three measurement directions can be used for the assessment of energy expenditure due to physical activity in situations of daily living. This variable was highly correlated with energy expenditure when all examined activities were considered together (r= 0.82), which represent the major part of the daily physical activity pattern
