AFAA Primary Group Exercise Study Guide questions with correct answers

List 8 health benefits associated with regular participation in physical activity. Answer decrease in: Resting heart rate, blood pressure, depression increase in: stroke volume, respiratory capacity, metabolic rate weight loss/maintenance, improved posture How can interval training improve athletic performance? Answer increase stroke volume= increased cardiac output increased tidal volume and breathing ratio= efficient use of O2 in blood increase CO2 removal due to high pulmonary ventilation= appropriate acid balance List 3 physiological adaptations that occur to improve exercise performance and state how or why improvement occurs. Answer increase of capillaries per muscle fiber= rich supply of O2 and nutrients rapid removal of CO2 and waste allows maximum energy production increase in glycogen & triglycoride storage in skeletal muscle increase in mitochondrial volume and activity= increase in enzymes Define ENERGY and it's food source. Answer Energy= the ability to do work. Food source is carbohydrates, protein, and fats. Define ATP. Answer High energy phosphate molecule required to provide energy for cellular function. Produced both anaerobically and aerobically and stored in the body.
