This depends on a few factors. A 75 kilogram or 165 pound person will burn between 628 (slow freestyle) and 864 (fast freestyle) Calories per hour of swimming, depending on how fast they swim. However, assuming it takes you 30 seconds to swim a lap of a 50 metre pool, you would do 100 laps in 60 minutes. This speed is faster than slow, but slower than fast, so you'd burn about 700 Calories per hour. Divide this by the number of laps you swim, and you answer would be 7 Calories per lap.
You can burn as many as 100 calories per hour just swimming casually in salt water. You can burn up to 500 calories per hour if you're swimming vigorously.
If someone is swimming for 35 minutes just for fun, it will burn around 300 calories. If swimming using specialized strokes, it could burn up to 500 calories.
You can burn up to 500 calories by swimming a mile using front crawl. This is at a high intensity.
