Protein intake recommendations Controversy has existed over the safety and effectiveness of protein intake above that currently recommended. Safety of protein intakes higher than RDA It is often erroneously reported by popular media that a chronically high protein intake is unhealthy and may result in unnecessary metabolic strain on the kidneys leading to impaired renal function.

Protein quality and common types of protein supplements To obtain supplemental dietary protein, exercising individuals often ingest protein powders. Protein timing It is generally recognized that active individuals require more dietary protein due to an increase in intramuscular protein oxidation [ 39 ] and protein breakdown [ 40 ] that occurs during exercise, as well as the need to further complement intramuscular protein resynthesis and attenuate proteolytic mechanisms that occur during the post-exercise recovery phases [ 41 — 43 ].

The role of BCAA's in exercise The branched-chain amino acids i. Conclusion It is the position of the International Society of Sports Nutrition that exercising individuals need approximately 1.

There does exist, however, published data to suggest that individuals habitually performing resistance and or endurance exercise require more protein than their sedentary counterparts.

The RDA covers protein losses with margins for inter-individual variability and protein quality; the notion of consumption of excess protein above these levels to cover increased needs owing to physical activity is not, however, given any credence. Notwithstanding, diet programs i. A framework for understanding dietary protein intake within the context of weight loss and athletic performance is laid out.

The aim of this review is to analyse the turnover flux and the relative oxidation rate of different types of muscle proteins after one bout of exercise as well as after resistance and endurance condition of training. Protein feeding in athletes appears to be a crucial nutrition necessity to promote the maintenance of muscle mass and its adaptation to the need imposed by the imposed technical requirements. In resting human individuals, the recommended protein daily allowance is about 0. Nevertheless, practical feeding recommendations related to regular exercise practice are proposed to athletes by different bodies in order to foster their skills and performance.
