3kg? Possible? Garmin stat say one?
3kg possible for longer distance / intensity that uses more of glyogen (and less of fats oxidation)
It is also due to glycogen depletion as well. Coz 1kg of glycogen used = approx 3kg of water released.
Glycogen is Stored with Water
When glycogen is stored in muscle tissue, water is stored with it. Roughly in a ratio of 3:1; meaning for every 1g of glycogen, 3g of water is also stored.
When glycogen is broken down, the water it's stored with is released. This water can be used by the body for various functions, including hydration. In some cases, it may be excreted in urine, according to research published in the National Institutes of Health (NIH).
Elaboration:
- Glycogen Storage:
Glycogen is stored in the liver and muscles, and it's stored in a hydrated form. For every gram of glycogen stored, approximately 3 grams of water are also stored.
- Glycogen Breakdown:
When the body needs energy, glycogen is broken down into glucose, which is used as fuel. This breakdown also releases the water that was stored with the glycogen.
- Water Use and Excretion:
The released water can be used by the body to maintain hydration, or it may be excreted through urine.
