The formula to estimate the calories burned during a power walk is:
Calories Burned=(METs×3.5×weight in kg)200×time in minutes
where METs is the Metabolic Equivalent of Task (4.5 for power walking), weight is the body weight in kilograms, and time is the duration of the power walk in minutes.
Power walking is a form of walking with a speed at the upper end of the natural range for walking gait, typically 4.5 to 5.5 mph. It is a low-impact exercise that aims to increase cardiovascular fitness and calorie burn, utilizing more muscle groups than regular walking.
Let's assume we have the following values:
Step 1: Convert weight to kilograms:
Weight in kg=1502.20462≈68.04 kg
Step 2: Use the formula to calculate calories burned:
Calories Burned=(4.5×3.5×68.04)200×30≈160.59 calories
Therefore, the calories burned during the power walk is approximately 160.59 calories.
