The swim start project was conducted with the Brisbane Grammar School (BGS) swim squad and the University of QLD School of Human Movement Studies. BGS athletes were analysed using three different start positions on the start block to assess which position gave them the best starting performance. Start performance was assessed by a range of variables such as reaction time, block time, flight time, distance to water entry, centre of mass flight and velocity. The analysis and feedback allowed the coach and swimmers to identify their individual best start position.
