Human Whole-Body Reaching In Normal Gravity And Microgravity Reveals A Strong Temporal Coordination Between Postural And Focal Task Components, Jerome Patron, Paul Stapley, Thierry Pozzo
Dr Paul J Stapley
Previous experiments by our group in normal gravity (1 G) have revealed spatial relationships between postural and focal components of whole-body reaching and pointing movements. We suggested that these relationships could be explained partly through the use of gravity to displace the CoM and attain the object or target position. In this study we compared human whole-body reaching in 1 G and microgravity (0 G) in order to more fully investigate how gravity contributes to strategies adopted for task execution and to determine possible invariant temporal relationships between multiple segments. Whole-body reaching movements made from the standing position in two …
