Protein

Introduction

Proteins are often referred as an essential aspect of all lives. They are one of the vital nutrients, whose fundamental structure form 20 different amino acids. The protein enhances the physiological functions, which is significant for the physical fitness and health. Under stress, proteins also act as a source of energy for the human body. In view of the fact that the body cannot store proteins; therefore, a steady supply is necessary (Creighton, 2003). The best protein sources include animal products such as meat, fish along with the milk products and vegetable products. Protein is the building material for muscles. The training stimulus can be converted by the body but only in muscle building if sufficient protein is supplied (Royston, 2009).

The daily protein intake should be about 2 grams per kilogram of body weight. Especially, the phase immediately after exercise should be seized to support the growth stimulation of the muscles quickly. A molecule of protein contains several tens to over 1000 amino acids. For instance, the hemoglobin molecule consists of 574 amino acids and has a molecular weight of 68,000. Protein intake is important to not only the quantity, but also the nature and composition (biological value) of proteins. Also, the amount of the individual proteins varied. The closer the amino acid pattern of the dietary protein is that of the body, the less need thereof is consumed and the higher is its biological significance (Creighton, 2003).

Discussion

The excess amount of proteins can adversely affect the physical condition and performance of the athletes. For the base of the endurance athlete's diet, it should be a proportion of 15% protein will be sought in the total energy demand. The proteins from the milk contain very different components that support numerous effects in the body. The two main factions of the ...
