EnEx – Energy Expenditure

Study Design

The EnEx (Energy Expenditure) database consists of data from ten subjects (3 female and 7 male, age 49 ± 12 years, height 178 ± 10 cm, weight 80.7 ± 14.6 kg, mean ± standard deviation (SD)). In one trial, each subject had to run on a traditional treadmill at three different speed levels ([3.2, 4.8, 6.4] km/h). In a second trial, an oscillating treadmill was used imposing different levels of physical activity. Each speed level lasted six minutes.

Hardware Equipment and Sensor Setup

Two SHIMMER sensor nodes were placed on right hip and right ankle. Each sensor node consisted of three accelerometer axes and three gyroscope axes. The sampling rate of the sensor nodes were set to 204.8 Hz. For the expended energy, the oxygen consumption was measured by a spirometry system. The sampling rate was 0.2 Hz.
