Lower risk of Type 2 diabetes 4. Lower risk of breast cancer 5. Reduced depression 6. Improved cardiorespiratory and muscular fitness 7. lower risk of colon cancer 8. prevention of weight gain 9. reduce chance of falling 10. improve cognitive function Define energy as a food source Correct Answer: Energy is the ability to do work and the main source is the sun List three physiological adaptations that occur to improve exercise performance and state how or why improvement occurs Correct Answer: 1. Increase maximal blood flow- Performing aerobic exercise forces larger volumes of blood which increases stroke volume 2. Increased O2 delivery and CO2 removal- the cardiorespiratory system saturates blood coming from the lungs with O2 efficiently. The high pulmonary ventilation assists with the removal of CO2 during exercise. 3. Increase maximal O2 update and aerobic power- regular aerobic exercise causes an increase in a number of capillaries per muscle fiber How can interval training improve aerobic performance Correct Answer: Maximizing aerobic power and increasing aerobic endurance and anaerobic power Define ATP Correct Answer: Adenosine Triphosphate intracellular carrier of chemical energy produced by the bod for muscular work 1 mole of ATP=1/10 energy walk What are the two energy pathways and describe them Correct Answer: Anaerobic: process of completely breaking down muscle carbohydrates that does not require the presence of O2 Aerobic: process of breaking down carbohydrates and fats with the presence of O2, which leads to an abundant supply of ATP; short spurt, high energy activities ATP-CP system/phosphagen system (anaerobic
