An optimal range of protein intake for an athlete trying to maintain current fitness and strength is 1.2 to 1.4 grams per day for every kilogram.

What are proteins?

Proteins are molecules made up of amino acids, and they play a fundamental role in the growth and maintenance of various tissues, such as muscle mass.

Characteristics of muscle-building:

  • Muscles are made primarily of protein and rebuild themselves, a process in which proteins are basic.

  • In order for a muscle-building athlete to keep muscles in good shape, it is necessary to synthesize more muscle protein than is consumed, which is known as nitrogen balance.

Therefore, we can conclude that the main determinants of an athlete's protein needs are his training regimen and usual nutrient intake.
