Paper Abstract:	Especially in the western countries health care is facing today growing challenges due to overweight of broad parts of the citizens as also due to aging societies in general. As consequence, an increasing number of researchers have turned their focus to the question of how health activities in daily life can be stimulated and monitored by computerized tools. As working base, such concepts often at first have to handle the sensing of physical activities ranging from simple body movements up to particular exercising, for which power walking and jogging represent quite typical samples. A recent trend in research is, e.g., to use for this purpose smartphones, since these devices are nowadays equipped with various sensors for acceleration, rotation and orientation. The corresponding fundamental question, whether this inviting approach of using sensors of commercial devices is really applicable and feasible in terms of accuracy, representatively is missing completely in such investigations. For complementing this research situation, the aim of the fundamental work here is a comparative evaluation of typical body movement sensing devices that are available on the consumer market. In controlled walking and slow jogging experiments, the accuracy of such devices was investigated and compared. The experimental results and the deducted limitations are discussed, and in the end these findings do suggest a rather critical use of commercial devices for the described purpose in health and sports monitoring concepts
