CARDIOVASCULAR TRAINING
• F.I.T.T. FORMULA–FREQUENCY– INTENSITY–TIME/DURATION–TYPE
FREQUENCY
• How often to exercise• Minimum – 3 X’s weekly• Maximum – 4-5 X’s weekly
INTENSITY

TARGET HEART RATE
• Exercise within your target heart rate to get maximum benefits of exercise
• Maintain range for at least 15-30 continuous minutes
• Maximum heart rate = 220 – age– Fastest your heart can beat without collapse
• Target heart rate range = 70-85% of maximum heart rate
Factors Affecting Heart Rate
• Sex: adult females average 5 – 10 beats per minute more than men due to supporting more body fat
• Size: Extra body fat causes the heart to work harder
• Temperature: A rise in body temperature will raise the heart rate eg. Hot tub, desert
• Ingesting food: It takes extra energy to digest a meal
• Posture: The more prone, the lower the heart rate.
