Accelerometry For Paddling And Rowing
Keywords: onwater accelerometry, paddling, rowing
AbstractIn paddling and rowing, analysis of the acceleration, velocity and impulse of the system (equipment and athlete) can aid in the appraisal of the stroke (technique) and the usefulness of equipment as it relates to each performer. To this point in time, the primary source of analysis has been through the use of cinema and video. Recently at the Sport Science Laboratory, Dalhousie University a convenient method of obtaining on-water acceleration data has been developed. The triaxial g analyst (Valentine Research Inc.), although created specifically for use in land vehicles, can record the horizontal linear acceleration, horizontal lateral acceleration and provide a friction profile of any moving aquatic craft. Synchronization with video allows the coach and athlete to analyze data of one stroke, or a series of strokes, or a complete race. Acceleration data from the g-analyst can be transferred to virtually any PC, and programs easily written to determine velocity and impulse. The g analyst and power source apparatus is light (l kg), easy to handle, and relatively inexpensive. Little room is required to house the apparatus and it does not interfere with the athletes in the canoe, kayak, rowing shell, or scull. Onwater accelerometry using the g analyst may prove to be an important analytical tool for detection of movement faults and for matching equipment to athlete(s) in paddling and rowing.
