I. Exercise Prescription 1. Mode or type of the exercise 2. Frequency of the participation 3. Duration of each exercise bout 4. Intensity of the exercise bout More intensity, longer duration More you work out, the more intensity II. Monitoring Exercise Intensity a. Can be qualified by i. THR- total heart rate 1. Based on the linear relationship between heart rate and VO2 with increasing rates of work a. The exercise intensity necessary to achieve a given percentage of VO2max results in a much higher HR than that same percentage of HR max i. Lower ranges, less effective to match VO2 max ii. MET- proxy measure, metabolic equivalent with a task 1. 10 min mile= 10 mets iii. RPE- rating of perceived exertion III. Karvonen method a. Adjusts the THR b. HR and VO2 correlate better at moderate to high intensities c. Uses heart rate reserve i. HRmax- HRrest 1. If an athlete it will be a small HRrest d. THR75%= HR rest + .75 (HRmax-HR rest) i. 48 + .75(136) = 150 IV. Metabolic Equivalent a. Amount of O2 consumed is directly proportional to the energy expended during physical activity b. Assumed that the body uses 3.5 ml of O2 per kg of body weight per min (3.5 ml/kg/min) at rest c. Activities can be classified by intensity according to their oxygen requirements V. 35 is an average VO2 max VI.
