Study Notes
History of Sports Nutrition
- Hippocrates (circa 460 BC) emphasized the importance of proper nourishment and exercise for optimal health.
- Roman gladiators consumed high-carbohydrate diets, including breads and stewed legumes, mainly as affordable meals rather than solely for energy during battles.
- Justus Von Liebig (1842) argued protein was the primary fuel for muscle contractions, but subsequent research established the roles of carbohydrates and fats in muscle energy use.
- Advances in the 1950s and 1960s, including isotopes and muscle biopsies, enhanced the study of nutritional science, particularly regarding muscle glycogen storage during exercise.
- Modern consensus recognizes the necessity of carbohydrates for high-intensity exercise and notes that fat oxidation diminishes during high-intensity efforts but increases with lower-intensity endurance training after 10-12 weeks.
