40m block starts today with the Freelap timing system on deck. Each athlete’s 40m sprint is broken down into 10m splits (0-10m, 10-20m, 20-30m, 30-40m) so we can see exactly how they accelerate and reach top speed. These splits help us pinpoint key performance zones: • Acceleration (0-20m): the explosive start out of the blocks. • Transition (20-30m): shifting gears into upright running. • Late acceleration to max velocity (30-40m): the final push toward top speed. From these splits, we can build a velocity curve – basically a graph of how fast an athlete is moving during each segment. This shows each athlete’s unique speed profile: where they’re strong and where they drop off. One sprinter might explode out of the blocks but plateau in the transition, while another starts slower but hits a higher top speed. By looking at the curve, we identify strengths, weaknesses, and improvement opportunities for each individual. And we don’t collect this data just for show. On the track, it ...
