The Best AFAA Primary Group Exercise Study Guide
List 8 health benefits associated with regular participation in physical activity. - 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? - 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. - 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. - Energy= the ability to do work. Food source is carbohydrates, protein, and fats. Define ATP. - High energy phosphate molecule required to provide energy for cellular function. Produced both anaerobically and aerobically and stored in the body
