Learning physics by experiment: V. Ambulation

A multitude of devices associated with developing and maintaining fitness have been introduced in the past decade or so; examples include activity trackers and other wearable instruments, which have the capability of wireless communication for sharing data that they capture. Although the use of such equipment is becoming more widespread, favorable health outcomes (such as weight loss and improved cardiovascular function) have either been too low to be noticeable or have only a small impact[1,2]. The purpose of this study is to compare these devices with those based on much simpler technology (that typically costs an order of magnitude less) to determine to what extent, if any, the considerably greater expense of the former provides commensurately greater benefits than the latter. Experimental procedure is limited to be appropriate for students at the introductory level. Parameters of interest include design, temporal, geometrical, physiological, environmental and human factors. The research conducted here not only expands the number of projects having a similar educational value[3], but also extends the variety.
