Factors that affect calories burned when swimming.
But don’t get caught up in these numbers, because calories burned depends on many factors.
– Body: The heavier person will consume more calories than the low weight person because it will need more energy to move the body bigger than the smaller body. (This is taken into account in the MET formula.) But a larger body will also create more surface area than water, thus creating more resistance. More resistance means more energy is needed to overcome resistance, thereby increasing your heart rate and leading to consuming more calories.
– Swimming speed: Swimming speed also affects the burning of calories. The slower you swim, the less energy is consumed, resulting in fewer calories burned. Therefore, the faster you swim, the more energy you will use. Using swimming equipment such as floats, ducklings, umbrellas and ice, to increase drag or increase traction will also increase energy consumption, increase calories burned.
– Swim style: Butterfly swimming is probably the hardest and most technically demanding, which is why it burns the most calories. When swimming the butterfly, you must pedal like a dolphin and your arms reach above your head, requiring the participation of the whole body muscles (especially in the core and upper back). Swimming strides the next in terms of calories burned when swimming. Every time you spread your arms, you’ll pedal at the same time! It is a perfect combination to burn large calories. Swimming frogs and backsteps are equivalent in calorie results. These are two slower swimming styles, but you can still burn calories with the right technique. Below are more specific estimates of the number of calories burned by each swim pattern.
• Floating (moderate exertion): 3.5 MET = 223 calories/hour
• Backstroke: 4.8 MET = 305 calories/hour
• Swimming frog: 5.3 MET = 337 calories/hour
• Freestyle or stride swimming (low or moderate exercise): 5.8 MET = 369 calories
• Free swimming or stride swimming (moderate to high exercise): 8.3 MET = 528 calories/hour
• Freestyle or stride swimming (fast or strenuous): 9.8 MET = 623 calories/hour
• Butterfly swimming: 13.8 MET = 878 calories/hour
How to burn more calories while swimming
Regardless of body size, pace, or type of swimming, the best way to burn more calories while swimming is to do strenuous exercise alternating with recovery time.
Example of a set of interleaved models: 50m freestyle sprint, then take a 10-second break for the heart rate to return to normal, repeat a total of five times. These intense efforts, along with rest, will require more of your body than training in a steady state – and science has shown that HIIT burns an additional 25 to 30% of calories, plus the following effect. Burn – burn calories even when the workout is finished.
