Metabolic measurements are sensitive to the activity level of the animal being measured. This chapter describes the various technologies available for recording the activity level of a study organism in synchrony with metabolic data, usually obtained using a flow-through system. These technologies include optical activity detection, in which information is extracted from fluctuations in light intensity; video activity detection; magnetic activity detection; capacitive activity detection; passive far-infrared activity detection; mechanical activity detection, often using a center of gravity sensor below a cage or chamber; and microwave reflectance activity detection.
