Exercise Physiology
| Question | Answer |
|---|---|
| Claudius Galenus | Gladiator doctor; anatomist, caused people to neglect the study for many years; "Laws of Health" |
| Augustus Flint Jr. | Published 5 textbooks; combined into "The Principles and Practice of Medicine" (first exercise physiology book) |
| Edward Hitchcock Jr. | Amherst Professor of Hygiene and PE; First to record annual statistical data on large group of subjects; proof-exercise is good |
| George W. Fitz | Helped create Dept. Anat., Phys. and Physical Training at Harvard (first formal exercise physiology class/lab); class died when he quit |
| Harvard Fatigue Laboratory | First major research lab to focus on the physiology of human movement and the effects of environmental stress on exercise; large influence because scientists went on to major positions |
| Exercise physiology | Study of how the body's structures and functions are altered when exposed to acute and chronic bouts of exercise |
| Sport physiology | Application of exercise physiology concepts to an athlete's training and performance |
| Metabolism | Breakdown of nutrients to create energy; catabolic or anabolic |
| Catabolic | Breaking things down |
| Anabolic | Building things up |
| ATP | Adenosine triphosphate; energy source for all cells; facilitates muscle contraction |
| Three metabolic pathways to synthesize ATP | Immediate energy system (ATP-PCr); Anaerobic glycolytic system (lactic acid); oxidative system |
| Substrate | Substance acted upon by an enzyme |
| Immediate energy system | ATP, PCr; very quick rate of reaction; duration 0-30s; limiting factor PCr depletion |
| Anaerobic glycolytic system | Glucose, glycogen; quick rate of reaction; duration 30s-3 min; limiting factors glycogen depletion, lactate accumulation (relative acidity); in cytoplasm and sarcoplasm |
