2007b]. They can be implemented to quantify characteristics and events that occur duringa dynamic activity. Traditionally these events were qualitatively analyzed using opticalmethods or by an athlete’s “feel”. The long term outcome from Brodie (2008) and Waegli(2007a, 2007b) is yet to be published but they have demonstrated that having quantitativedata will allow for a more accurate and detailed analysis of dynamic events and will bebeneficial for product development and coaching techniques.The implementation of GPS, an IMU and an axial load cell should allow for datacollection of the desired performance parameters previously described. Skier and boatGPS modules will be able to provide normalized skier velocity. An IMU located on thewater ski will provide ski orientation, acceleration and deceleration and an axial load cellin series with the tow rope will provide rope load. Capturing the performance parameterswill allow for improved proved product development, coaching techniques and injuryprevention within the water ski industry.1.4 MethodologyThere are several uncontrollable factors that can have an influence on the performance ofa water skier and the development of an experimental procedure that would minimizetheir effect is essential. Human participants were recruited based on their skiing ability,the criteria being that they could comfortable ski two passes of a slalom course four timesthroughout each test day. Six subjects, with an advanced skill level, were selected and8
