Enter the total breast stroke time (min) and the body weight (lbs) into the Calculator. The calculator will evaluate the Breast Stroke Calories. 

Breast Stroke Calorie Formula

BSC = BST / 60 * 400 * BW/150

Variables:

  • BSC is the Breast Stroke Calorie (calories)
  • BST is the total breast stroke time (min)
  • BW is the body weight (lbs)

To calculate Breast Stroke Calories, divide the total breast stroke time by 60, multiply by 400, then multiply by your body weight over 150.

How to Calculate Breast Stroke Calories?

The following steps outline how to calculate the Breast Stroke Calorie.


  1. First, determine the total breast stroke time (min). 
  2. Next, determine the body weight (lbs). 
  3. Next, gather the formula from above = BSC = BST / 60 * 400 * BW/150.
  4. Finally, calculate the Breast Stroke Calories.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total breast stroke time (min) = 50

body weight (lbs) = 195

Frequently Asked Questions

How does body weight affect the number of calories burned during breast stroke?

Body weight plays a significant role in determining the number of calories burned during breast stroke. Heavier individuals tend to burn more calories than lighter individuals for the same duration and intensity of swimming because their bodies require more energy to move through the water.

Can the breast stroke calorie formula be used for other swimming strokes?

No, the breast stroke calorie formula is specifically designed for calculating calories burned during breast stroke swimming. Different swimming strokes, such as freestyle or butterfly, have different intensities and techniques, which affect the calorie burn rate. Separate formulas are required for other strokes.

Why is the number 400 used in the breast stroke calorie formula?

The number 400 in the breast stroke calorie formula represents an average metabolic equivalent (MET) value for the breast stroke, which is used to estimate the energy expenditure of physical activities. It is a factor that helps translate the effort of swimming into calories burned, based on average data.

Is it possible to increase the calories burned during breast stroke?

Yes, increasing the intensity or duration of the breast stroke can lead to a higher calorie burn. Additionally, incorporating intervals of faster swimming or using swim training tools like fins or hand paddles can also increase the resistance and intensity, leading to more calories being burned.
