MEASUREMENT SET UP FOR THE EXPERIMENTAL STUDY OF THE DYNAMICS OF HOPPING

Hopping is a gesture that, though simple, is apt to providing precious information on human-body dynamics, including dynamic stability. Currently available studies are normally based on a limited set of sensors and scarcely provide metrological details. This paper presents a new multi-sensors measurement set-up, including acceleration, force, angles and image-based positions. The metrological characteristics of the system are discussed, including systematic and random uncertainty contributions, measurement conditions and procedure. The same experimental apparatus may be used for studying other motion gestures, such as stepping down, forced hopping or cycling, thus providing a flexible experimental tool.
