Document Summary
Chapter #2: distinguish between physical activity and exercise. Physical activity: any activity above resting levels, such as going for a walk or gardening. Exercise: a subset of physical activity that is planned, structured, and repetitive, such as swimming for 30 minutes three times per week. Physical activity will not necessarily improve your fitness levels, whereas exercise is a term used to suggest an intensity of activity that will improve fitness components: describe the four principles of physiologic conditioning. Overload principle: stress the bodies system (increase frequency while maintaining intensity or increase instensity while maintaining duration or increase duration while maintaining intensity). Specificity principle: specific exercise elicits specific adaptations that create specific training. Reversibility principle: once you have reached a desirable level of physical fitness, you must exercise to maintain that level (prevent de-conditioning). Individual differences principle: there are limits to the amount they can adapt. Heart rate reserve: maximal heart rate resting heart rate (50-85%)
