I've recently thought to measure my weight before and after exercise sessions, and was surprised by the result. I assume that the loss over the session is almost exclusively water loss.
Are these sorts of numbers normal, and if not are they a problem?
- Baseline weight pre-exercise: 93-95kg (6ft 1; male; 32)
- Over a 25-30 minute run, with no drinking: 1 - 1.5kg weight loss.
- Over a 1.5 hr elite-level (field) hockey training session, with regular drinking: Drink 1 - 1.5 litres of water, and still have a total weight loss of 1.5 - 2 kg.
(To set a scale for 'elite-level': I don't play international hockey, but ~1/2 the players at the session do/have, and 4 were in Tokyo this year. I'm not 'keeping up' with them; I am just about at a level for it not to be a farce.)
