Physical Activity - ️️Any bodily movement produced by contracting skeletal muscles, with an increase in energy expenditure. Exercise - ️️Planned, purposeful, repetitive Physical Fitness - ️️Attributes or characteristics that individuals have achieved that related to their ability to perform physical activity 3 metabolic pathways the body uses to creates ATP - ️️1. Creatine Phosphate 2. anaerobic glycolysis 3. 0xidative system Claudication - ️️pain in the leg is induced by exercise, usually because of an artery obstruction. Creatine Phosphate system - ️️Small amounts of CP are stored within each cell. Simple one-to-one trade off that allows for the rapid production of ATP. ONLY for use during short bouts of exercise. less that 10 seconds. Anaerobic glycolysis - ️️No oxygen required. NExt most immediate energy source. break down carbs (glucose or glycogen) into pyruvate. Used during medium-duration exercise. no more than about 90 seconds. Aerobic glycolysis (oxidative system) - ️️Oxygen dependent. As exercise intensity decreases allowing for longer duration activities, use of the oxidative system increases. (Krebs cycle and ETC). Produce ATP in the mitochondria of the cell--requires oxygen. Lasts longer than 1-2 minutes.
