There are lots of cardio myths floating around so here's the results of a test from Gotime Training.com. They used Polar FT7 Heart Rate Monitors to see what truly burns more calories: High Intensity Interval Cardio (HIIT) or low intensity steady state cardio. Here’s the breakdown of each cardio session:
LOW INTENSITY STATE STATE
Duration: 69 minutes
Calories burned: 491
Average heart rate: 109 bpm
Max heart rate: 120 bpm
Results: 7.12 calories burned per minute
HIGH INTENSITY INTERVAL TRAINING
Duration: 17 minutes
Calories burned: 210
Average heart rate: 142 bpm
Max heart rate: 161 bpm
Results: 12.4 calories burned per minute
The results show that HIIT burns 42.6% more calories per minutes than low intensity steady state cardio. But the low intensity state cardio burned more calories, right? Yes, but who has hours to spend walking when you could simply amplify your cardio and get a much greater return on your efforts. On top of producing a greater calorie burn rate HIIT also offers these benefits over low intensity steady state cardio:
preserves muscle mass
increased Excess Post-Exercise Oxygen Consumption (burn more calories after the training)
significantly increased aerobic and anaerobic fitness
decreased fasting insulin and increased insulin sensitivity
reduced abdominal and subcutaneous (under the skin) fat
stimulates hormones to increase metabolic rate
Get off the treadmill for hours and get after some HIIT! Try sprinting, rower, or body weight resistance training intervals. I prefer the stair climber and find I even burn more calories per minute.
We put our heart rate monitor to the test and put a few cardio myths on the chopping block. Learn why HIIT cardio rules when it comes to burning calories.
