NHM 315 1nd Edition Lecture 4Outline of Last Lecture I. Chapter 4Outline of Current Lecture II. Chapter 5Current Lecture Protein Quality-Proper amounts and types of amino acids-Animal and plant proteins differ-Animal proteins are termed complete-Plant proteins are termed incompleteProtein Catabolism-Amino acids are not “stored” for future use-Amino acids can be used for energy-Gluconeogenesis-4 kcal/ g-Not the preferred source of energy for exerciseProtein Recommendations as a relative amount-10% of total energy intake is typically equal to 0.8g/kg/day-General guideline if energy intake is adequate:-1-2g/kgRecommended protein intake for vegetarian athletes-General recommendation + 10%-Takes into account lower digestibility of plant proteins-Energy intake should be sufficient-Emphasize protein- rich vegetarian sourcesTiming of protein intake-Protein consumption before exercise -Insufficient evidence to show benefits-Protein consumption during exercise-Some studies show benefitsThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.-Protein consumption after exercise-Take advantage of “anabolic window”Intake of protein above recommended levels-Short-term effects-Short-term, high protein intake seems to be safe in healthy adults-Adequate fluid intake needed to prevent dehydration-Protein intake in relation need for CHO and fat-Long-term effects-Increased calcium excretionEnergy Restriction and Protein intake by athletes-Long term, substantial energy deficits-More protein intake in athletes with disordered eating or eating disorders-Long term, Small energy deficits-Pattern of eating may be small daily energy deficits-Increasing daily protein intake is essentialIntake of protein below recommended levels-Body cannot maintain protein balance-Skeletal muscle mass and functionality are reduced-Immune system is negatively
