Power yoga is a general term for any type of yoga that emphasizes strength and flexibility. This type of yoga can burn a significant number of calories, depending on the specific movements that it requires. You can calculate the calories you burn with one hour of power yoga by using several different standard formulas.
Estimate
You can obtain a rough estimate on the calories you burn from an hour of power yoga by using only your weight. BuddySlim estimates that you burn 501 calories during an hour of power yoga if you weigh 154 lb. This estimate doesn't account for your physical condition, age or gender.
Considerations
It's important to remember that power yoga may be any form of high-intensity yoga, and does not refer to any particular routine. The specific routine can vary greatly depending on your skill level, even within a given power yoga class. The calories you burn during a power yoga class can therefore vary greatly.
Heart Rate
The accuracy of your calorie expenditure calculation increases greatly when you take your heart rate into account. This technique requires you to keep your heart rate within a target range of 90 to 150 beats per minute. This is the range over which your heart rate correlates most closely with your calorie expenditure rate. You may need to increase or decrease the difficulty of your movements to keep your heart rate within your target range.
Measurements
Most heart rate monitors today allow you to record your average heart rate over a specific time interval. This will allow you to obtain your heart rate during an hour of power yoga. You can obtain your weight with a bathroom scale, and the calculation also requires your gender and age.
Calculation
The following equation calculates the calorie expenditure for an hour of activity for women: Calories = [(Heart Rate x 0.4472) -- (Weight x 0.05741) + (Age x 0.074) -- 20.4022] x 60/4.184. The equivalent equation for men is: Calories = [(Heart Rate x 0.6309) -- (Weight x 0.09036) + (Age x 0.2017) -- 55.0969] x 60/4.184.
