No sniggering down the back, now!
The 2-litre rule
Research has clearly shown that a reduction in bodyweight as little as 2%, due to dehydration, can decrease performance by up to 20%. To maintain optimal performance, Bob Smith, a senior consultant to British Swimming, has our top Olympians using the 2-litre rule to help maintain hydration.
Every evening each swimmer places a 2-litre bottle filled with drinking water into the fridge. Throughout the next day the contents must be drunk so that by the evening the empty bottle can be refilled and placed in the fridge for the next day.
This water is in addition to that consumed during training, where at LEAST 1- litre of water should be drunk every hour.
Lets all stay well watered in the water!
