During moderate to intense exercise, we can produce up to 2 litres of sweat per hour depending on individual sweat rates and the environmental conditions that surround us. Sweat contains vital electrolytes which are essential for numerous bodily functions such as hydration and the regulation or nerve and muscle function. SiS Hydro Tablets contain essential electrolytes such as sodium, calcium and magnesium to help keep us hydrated during exercise.
If fluid and electrolyte losses are not replaced, dehydration arises which is a major cause of fatigue. Dehydration will augment fatigue through elevated cardiovascular strain, thermal strain, increased heart rate and rate of perceived exhaustion (how hard we perceive the exercise to be), muscle lactate production and glycogen utilisation (we deplete carbohydrate stores quicker meaning we have less for the exercise bout). SiS GO Hydro can help prevent this, with the aim not to lose more than 2% of our body mass through sweat.
General recommendations*
BEFORE EXERCISE
2 hours before exercise, drink 6 to 8ml of fluid per kg of body weight to allow time for absorption and removal of any excess, having sodium before exercise will stimulate thirst and promote the retention of fluids.
DURING EXERCISE
Drink regularly, in small amounts with the aim of consuming enough to prevent excessive dehydration (reductions from baseline body weight greater than 2%). Using SiS GO Hydro during exercise will also replace essential electrolytes, though you can consume before or after exercise also (do not consume over 4 tablets per day).
AFTER EXERCISE
Post exercise you should aim to consume 1.5 L for each kg of body weight lost (this is enough to also take into account the fluid that is naturally lost from the body via urine). This does not need to be consumed all at once though, aim for ~ 500ml immediately post-exercise then regular intervals after that. The easiest way to calculate your fluid loss is to weigh yourself before and after training.
