The science of sports drinks college blok 2.3
The concentration of a substrate in the blood is not necessarily representable of what is happening in
the skeletal muscle. To know this, you should take skeletal muscle tissue: biopsy. You can study this
underneath a microscope, and you can study the muscle metabolism. Based on this information, you
can develop sportsdrinks.
Every skeletal muscle tissue consists of myo fibers, which consist out of myofibrils.
Protein isn’t an important fuel: only carbohydrate and fat in normal conditions.
Endogenous energy stores:
Fat : most energy:
- 12.000 gram in adipose tissue.
- 300 gram in skeletal tissue: intramyocellulair lipids.
- Always some fat in the circulation.
Carbohydrate:
- 100 gram in liver.
- 350 gram in skeletal tissue.
- 20 gram in circulation.
Fat Carbohydrate

Large storage capacity (500 MJ) you can store Limited storage (8MJ)
a lot for a limited gain of weight.

that you can get from the processing of an
amount of fat. This is diesel.
Capacity to burn fat decreases at high intensity exercise. Muscle glycogen is the most important.
Glucose never leaves the muscle. The only organ that puts glucose in the circulation is the liver.
Dietary intervention targets
- Before competition: optimize muscle glycogen stores.
- During competition: exogenous carbohydrate administration.
- After competition: ppt.
Before competition
6 days before a competition you start to increase the amount of carbohydrates in your diet. To get the
same energy intake, you don’t have to eat more in the energy perspective, but you do need to eat
more in kilograms, since: carbohydrat 17 kJ/kg, but fat is 38 kJ/kg!
You increase the carbohydrate intake till about 77% of diet.
In these 6 days, you do tapering: not reducing the intensity of your exercise, but the duration.
You do in the days before the competition:
- Modified supercompensation diet.
