The starting blocks exert an equal magnitude reaction force forward and upward on the sprinter's feet at the exact same instant. The starting blocks exert a greater force forward on the sprinter than the sprinter exerts backward on the blocks. The sprinter experiences a delayed forward force once the muscles fully contract. The reaction force acts downward into the track surface, accelerating the earth away from the sprinter.
