Document Summary
Energy systems and metabolic pathways: energy sources, carbohydrates (cho) Sugars and starches that provide rapid forms of energy: glucose, glycogen, fats. Composed of fatty acids with high energy potential: stored as triglycerides and within fat cells that form adipose tissue, cholesterol is a type of fat (steroid) the body does not use for energy production, proteins. Atp production occurs via anaerobic an aerobic metabolism: anaerobic: with out oxygen, aerobic: with oxygen, anaerobic vs. aerobic metabolism, anaerobic- Used for high intensity activities such as power lifting and sprinting: aerobic- Forms atp via glycogen and free fatty acids. Used for endurance activities in which muscles must repeatedly contract over time: anaerobic metabolic pathways, phosphagen system (atp+pc) Produces immediate energy for maximal intensity activities: power lifting, 100m sprint, football. Replenishment of pc stores occurs within 2-5 minutes of rest. Stored glycogen (within muscle) is rapidly broken down to produce atp and lactate.
