Sports Nutrition
In a car you have spark plugs. With old or inadequate
spark plugs, the car does not run efficiently. Additionally, even if you
put premium petrol, the car will not run well. The spark plugs have to
be in good condition for the car to run well. Vitamins and minerals can
generally be thought of as spark plugs in the body.
Truly, adequate vitamins and minerals are needed
to thoroughly utilise the macronutrients (carbohydrates, protein and fats).
Additionally, since the athlete utilises large
amounts of oxygen, there is a tremendous amount of free radicals being
produced. So not only do athletes need a good supply of vitamins and minerals
to be able to thoroughly utilise the food they eat, they also need additional
antioxidant nutrients (Vitamin C, E and Beta Carotene) to minimise the
free radical damage that can occur.
By minimising the free radical production that
occurs with sport, the athlete can potentially reduce the amount of recovery
time needed between sporting events. Reducing free radical damage may
reduce the amount of muscle fibre degradation, thus reducing muscle soreness.
Additionally, glycogen (the carbohydrate that is stored in the muscle
and available for immediate usage) may be re-synthesised more quickly
in the presence of antioxidant nutrients and low levels of free radicals.
The three antioxidant nutrients work together.
Vitamin C is water soluble and works in the plasma area (liquid area).
Vitamin E and Beta carotene are both fat soluble. The cell membrane is
a lipid structure, made up of fatty tissue, and since Vitamin E and Beta
Carotene are both fat soluble, they sit on the cell wall and cross over
into the cell. So the cell has protection from the free radicals three
fold: plasma, cell wall, and intercellularially
The above information regarding free radicals and
antioxidant nutrients can be summarised simply by: when the body burns
fuel, its combustion processes (metabolic functions) create exhaust in
the body. As our body does not have an exhaust pipe, we must have ways
to get rid of this exhaust build-up. This can be done with antioxidant
nutrients. Antioxidant nutrients help reduce the damage of this exhaust
build-up (free radicals) in the body.
