Exercise increases protein needs for athletes, potentially by 50-100% for endurance athletes. However, most athletes already consume sufficient protein, so higher intake may not boost performance.

Area of Science:

  • Exercise Science
  • Nutritional Biochemistry
  • Sports Nutrition

Background:

  • Historically, exercise's impact on protein requirements was underestimated.
  • Athletes, particularly strength athletes, have traditionally consumed high-protein diets.

Purpose of the Study:

  • To investigate the effect of exercise on protein and amino acid requirements in athletes.
  • To determine optimal protein intake ranges for athletic performance and muscle development.

Main Methods:

  • Review of recent investigations on strength and endurance athletes.
  • Analysis of protein intake patterns in athletes compared to sedentary individuals.

Main Results:

  • Regular exercise increases protein needs, especially for endurance athletes (50-100% increase).

  • Data for strength athletes suggest excess protein may aid muscle growth, but optimal levels are less defined.
  • Many athletes consume 150-200% of recommended protein intake, potentially negating benefits of further increases.

    • Conclusions:

    • While exercise elevates protein requirements, most athletes meet or exceed these needs through diet.
    • A protein intake of 12-15% of total energy is likely adequate for both endurance and strength athletes, provided energy intake is sufficient.
    • Increased protein intake beyond current levels may not enhance athletic performance for many athletes.
