Unit 6572 Nutrition and Physical Activity BALANCED NUTRITION FOR ATHLETES Your diet should be optimal in both quality and quantity of food, in order to replenish your energy reserves and avoid fatigue or inadequate nutrition. A good diet will help your body perform at its best. Even though athletes often have varying nutritional requirements, they too must follow a healthy diet for normal bodily function. This includes the recommended intakes of macronutrients and micronutrients. Food labels can provide useful guide for identifying specific foods. Be careful of the contribution of additives and preservatives to micronutrient values. The Four Macronutrients Function Storage Carbohydrate Provides the greatest contribution to energy intake to use on moderate to high intensity exercise Mostly in muscle Some in liver Stored in limited amounts – needs to be continually replenished Protein Growth, develop and repair of muscles/tissues O 2 carriage Prevent of illness (immune function) Chemical reactions A minor energy source Muscle, bone, tissues, etc Fat Convenient and concentrate source of energy Provides most of the energy for daily living Absorbs and transports fat- soluble vitamins (A,D,K,E) Body insulation Body cushioning and protection Subcutaneous Surrounding organs Around joints Muscle Alcohol usually converted to fat *See your 6571 notes for a more in depth description of each macronutrient In terms of energy production, carbohydrate, protein, and fat fuel aerobic metabolism (energy production with oxygen), while carbohydrate is also used in anaerobic glycolysis (energy production without the presence of oxygen). 2

Unit 6572 Nutrition and Physical Activity Energy System Description Duration Fuel Aerobic long-term energy system ATP produced in the presence of O 2 Medium – low intensity activity eg long-distance running 60s-days Carbohydrate fat protein Anaerobic Lactic Short-term energy system ATP without the presence of O 2 High intensity activity eg sustained sprinting such as 400m sprint 10s-90s Carbohydrate ATP-CP Immediate energy system ATP without the presence O 2 High intensity activity eg short sprints 0-10s ATP CP Aerobic Energy Production – Carbohydrate & Fat While three macronutrients fuel the aerobic energy system, they contribute in varying amounts; fat and carbohydrate providing the vast majority of fuel. The greater the intensity of aerobic exercise, the greater the contribution of carbohydrate is used to provide energy. If you start training with high levels of

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
