Wondering why they wear arm sleeves but no socks? Here's the lowdown.
Hurdlers Grant Holloway and Rai Benjamin are gold medal favorites as well. Benjamin is competing in the 400 meter hurdles, while Holloway is handling the 110 meter hurdles. And in the 1,500 meters, Matthew Centrowitz became the first American man since 1908 to win the gold at Rio, and he’s defending his title.In events from 100 to 400 meters, including the hurdles, athletes are required to use starting blocks.
In the shorter dashes, blocks are also very helpful in providing a solid platform for the athlete to push off of in order to get a more powerful and rapid start. The first stride that a sprinter takes is the longest and the starting blocks allow the sprinter to increase their acceleration and position themselves upright to move as fast as possible.
This explosive movement before getting in the blocks helps activate neurons and muscle fibers to prepare for the demands of the sprint to follow. It is called Post-activation Potentiation by sports scientists.
