How many calories will 850 pound person burn if he or she walks 2 mph for 1 ahr
The calorie burn during walking varies based on several factors including weight, speed, and intensity. However, using a rough estimate, a person weighing 850 pounds would burn approximately 113 calories per hour while walking at 2 mph.
To estimate the number of calories burned during a walk, you can use the MET (Metabolic Equivalent of Task) value. The MET value represents the energy expended for an activity relative to resting metabolic rate.
The MET value for a 2 mph (3.22 km/h) walk is approximately 2.9 METs. To calculate the calories burned per minute, you can multiply the MET value by the weight in kg and divide it by 200.
Since you mentioned an 850-pound person, let's convert that weight to kilograms. 850 pounds is approximately 385.6 kilograms.
Calories burned per minute = (MET value * weight in kg) / 200
Calories burned per minute = (2.9 * 385.6) / 200
Calculating this gives us approximately 5.58 calories burned per minute.
Now, if the person walks for 1 hour, the total calories burned would be:
Total calories burned = calories burned per minute * number of minutes
Total calories burned = 5.58 * 60
The estimated number of calories burned for an 850-pound person walking 2 mph for 1 hour is around 334.8 calories.
To calculate the number of calories burned during any physical activity, you can use a formula that considers an individual's weight, the intensity of the activity, and the duration of the activity.
The formula to estimate the calories burned while walking is:
Calories Burned = (MET * weight in kg) * (duration in hours)
MET (Metabolic Equivalent of Task) is a unit that represents the energy expenditure of a specific activity compared to the resting metabolic rate. For walking at a speed of 2 mph, the MET value is approximately 2.9.
Now, let's break down the steps to calculate the calories burned:
1. Convert weight from pounds to kilograms:
Divide weight by 2.205
Weight in kg = 850 pounds / 2.205 = 385.05 kg (rounded to two decimal places)
2. Calculate the calories burned:
Calories Burned = (MET * weight in kg) * (duration in hours)
Calories Burned = (2.9 * 385.05 kg) * 1 hour
Calories Burned = 1116.15 calories (rounded to the nearest calorie)
Therefore, an 850-pound person walking at a speed of 2 mph for 1 hour will burn approximately 1116 calories.
