When comparing exercises or activities in terms of number of calories burned, you are really asking how much energy is required for each activity. To explain this in more detail, the body actually needs the calories you eat every day as a source of energy; which means that the more you train, the more calories you will burn. The math varies drastically based on factors like age, gender, weight, fitness level, and more. When it comes to how much you burn from swimming and other cardio exercises, an estimate can be made by measuring the amount of oxygen consumed during the activity.
It takes a long time to learn to swim, a lot of skill and technique to do the exercise well. Compared to other cardio exercises, many people know how to run, jog, row and bike with ease. However, in order to swim, one needs to practice properly. That said, someone who is not efficient at such a water sport would burn more calories than someone who is already an expert, since less effort is put in. Experience also plays an important role. For example, if you’re not very familiar with a sport and you feel like you’re pushing yourself too hard, you may think you’re burning a lot of fat but the truth is you’re only working at a medium intensity, but I just feel like it’s already intense.
Swimming at a speed of 1:15 every 100 meters will burn between 15 and 25 kcal per minute. An hour of extreme activity in the water would burn approximately 1,000-1,500 kcal. Just looking at these values proves that sport is one of the best exercises that can be used to combat obesity as it melts fat due to the number of body parts involved. Compared to other cardio exercises, running at 8:00 per mile will consume between 10 and 20 kcal per minute. This means that one hour would only consume 800-1000 kcal. Riding a bike at 10 miles per hour uses 6 to 10 kcal per minute, which means only 900 to 1,200 kcal per hour.
