New research by Dr R Mann and the USATF has shown that elite sprinters whether male or female attain over 50-60% of their maximal velocity after the first two strides of the 100m sprint. With the Olympics being one of the worlds biggest sporting events, the 100m sprint particularly the men’s race, is one of the most prestigious events in the tournament. As a result, the physical and physiological demands placed on an athlete are unique to the … The 100m sprint has four distinct phases that should be addressed by the coach – the start, the acceleration phase, the transition phase and the maximum velocity phase (Winkleman, 2009).
