Document Summary

Nutrition and physical activity: lecture recording available by monday, small quizzes on canvas for participation, 2 points per evaluation of course evals if at least 70% participates. Types of exercise: resistance, cardiorespiratory, neuromotor, flexibility. Nutrient utilization during physical activity: energy sources during activity, macronutrients, energy comes from carbs, proteins, and fats, glucose > fatty acids > amino acids > energy. Fuel sources during activity and exercise: fat is used before carbohydrates, at 65% energy you burn the most fat. Carbohydrate needs: main fuel source for most activities, need to consume a diet moderate to high in carbohydrates, recommended 6-10 g carbs/kg body weight/day. Importance of glycogen stores: carbohydrate-deficient diet rapidly depletes muscle and liver glycogen, carbohydrate depletion during prolonged exercise results in reduced exercise capacity. Fat needs: 20-35% of total kcal form fat, rich in mufa and pufas, limit saturated and trans fatty acids.
