indoor vs. outdoor track
indoor and out door track are very different (at least for the throwing events). outdoor you are throwing on a concrete surface with a metal shot put. But for indoor, you are throwing a plastic cased shot put with beads inside and normally throwing on a wooded surface. the indoor shot put is also bigger in size. this will help the athletes get a better push on the shot so that they can get a better flick. this normally causes a better throw. Moth athletes that throw shot put actually prefer indoor because of the side of the shot put.
