Summary Introduction
To review:
The importance of consumption of a diet with large amounts of complex carbohydrates for a day or two before the competitive event by the athletes.
Introduction:
Carbohydrates are organic molecules that are utilized by the individuals for the production of energy. These are broadly categorized as a monosaccharide (simple sugars), oligosaccharide (few monosaccharides linked together), and polysaccharide (multiple monosaccharides linked together). Polysaccharides are also called as complex carbohydrates.
