Kinesiology 110 Spring 2009 Professor Braun Lecture 17 questions - 1. Does exercise at a lower intensity “burn more fat” than exercise at a higher intensity? - Chars are on the wall of almost every gym - The idea is that exercise at a lower % of maximal heart rate is more effective to “burn” body fat and manage weight - First, what is the importance of maximal heart rate (MHR)? o The intensity of exercise based on VO2 max is difficult to measure b/c it requires expensive and rare laboratory equipment o On the other hand, everyone can estimate heart rate by taking their pulse at the radial artery - Count beats for 10 seconds and multiply by 6 (or count for 15 seconds and multiply by 4) to get heart rate in beats per minute - The intensity of exercise is determined by comparing your heart rate to your maximal heart rate (Max HR) - Max HR is mainly a function of your age: it goes down as you get older o Training does not affect Max HR. - Traditional Formula to calculate MHR o Max HR = 220 – age in years So at age 20, Max HR = 200 At age 50 , Max HR = 170 - Newer formula o Max HR = 208 – (0.7 * age in years) So, at age 20, Max HR = 194 At age 50, Max HR = 173
