The document consists of a questionnaire focused on human physiology during aerobic exercise, covering topics such as ATP production, sources of carbohydrates, and energy utilization. Key answers indicate that mitochondria are the main site for ATP production, fat and carbohydrates are primary energy sources in endurance activities, and adaptation to training is related to the specificity principle. Additionally, it notes that protein synthesis decreases during exercise but increases afterward.
Questionnaire science of exercise
- 2. The major site of ATP production during aerobic exercise is • Sarcoplasmic reticulum • Mitochondria • Hemoglobin • Cell nucleus Answer - Mitochondria
- 3. Which of the following is a source of carbohydrate for the body during exercise • Muscle glycogen • Blood glucose • Liver glycogen • All of the above Answer – All of the above
- 4. What are the primary source of energy during a marathon • Creatine phosphate • Fat and carbohydrate • Fats only • Carbohydrate only Answer – Fat and carbohydrate
- 5. Which is true regarding fuel stored in the body • There is significantly more carbohydrate than fat • There is significantly more fat than carbohydrate • These fuels will not deplete during any exercise • There are equal amounts of carbohydrate and fat Answer – There is significantly more fat than carbohydrate
- 6. Endurance training will result in • An increase in carbohydrate utilization and fat sparing • An increase in fat utilization and carbohydrate sparing • An increase in fat and carbohydrate utilization • A decrease in fat and carbohydrate utilization Answer - An increase in fat utilization and carbohydrate sparing
- 7. The respiratory exchange ratio is • 0.70 for carbohydrate • 1.0 for fats • A ratio of carbon dioxide produced to oxygen consumed • A ratio of oxygen consumed to carbon dioxide produced Answer - A ratio of carbon dioxide produced to oxygen consumed
