After completing a dive, swimmers climb out the pool and head immediately to a bank of showers that stand close to the diving boards. Then, in full view of the crowd and TV cameras, they take a shower. Divers keep their suits on, of course, usually appearing only to rinse off their hair and arms. Oftentimes, the divers will receive their scores while still showering off. What`s the purpose of this? Divers shower in between each dive to keep their muscles warm after getting out of the pool. The temperature of the pool water and the air are usually different. This difference can cause muscle tightness. To combat this, divers warm up in either the showers or a hot tub.
