I am often asked questions related to nutrition... fat burning versus carbs, pacing, etc. When clients ask me about feeling tired and is this possibly bonking.... I say it can be, but it can also be issues with hydration.
I will list a few items of interest....
1. If an athlete is 2% dehydrated... their performance is also reduced.... by 11%!
2. Most rehydration drinks have sodium chloride as a primary electrolyte. Sodium chloride can create bloating and dehydration since water from the body (plasma) has to travel to the gut to dilute Sodium chloride for absortion. These types of drinks are best used as a preload the night prior or at least 3 hours before a long endurance or high intensity session.
3. The same absortion routine must take place for most refueling drinks because of the high concentration of carbohydrates in the drinks. Yes... water has to leave other areas of the body (plasma) to dilute carbs. So, if an athlete is close to being dehydrated they feel tired or bonky. They take in carbs and then get really dehydrated. Sound familiar?
4. Other sourses of sodium such as citrate and bicarbonate transfer into the blood stream without that bloating effect. A bonus to these types of electrolytes is they also have a lactate buffering effect.
