CARDIOVASCULAR FITNESS A man's health can be judged by that which he takes two at a time - pills or stairs. - Joan Welsh
Definition and Facts • Cardiovascular Fitness: The body’s ability to provide oxygen to working muscles • Cardiovascular disease is the leading cause of death in the US (831,272deaths in 2006; 34.3 %of all deaths) • Cardiovascular disease accounts for more deaths than all other diseases combined • Unhealthy diet and a lack of exercise (especially aerobic exercise) are the two biggest factors
Aerobic vs. Anaerobic • Aerobic = Long in duration and moderate intensity (with oxygen) • Anaerobic = Short in duration and High intensity (without oxygen) 4 ways to tell if an activity is aerobic • Must use large muscle groups of body. • Increased respiration • Increased sweat • Increased heart rate (60-80 % of MHR for at least 25 minutes) If all four are present it is good indicator
TARGET HEART RATE • 220 (max beats/minute) - age = Age Adjusted MHR • Adjusted MHR * 0.60 (60%) = Lower limit • Adjusted MHR * 0.80 (80%) = Upper limit Target Training Zone is between Lower Limit and Upper Limit
Ways to Increase Aerobic Workload (FIT) • FREQUENCY increase (how often): 4-5 times/week • INTENSITY: 60-80% MHR • Increase intensity by either: • Decrease time with same distance • Increase distance with same time • TIME increase: At least 25 minutes minimum (ramp effect) • Same pace for longer time Oxygen is the last electron acceptor in the Krebs Cycle
