Teknik ile alakalıymış cidden bak burada yazıyor:
In swimming, skill and technique significantly impact energy expenditure. Most people know how to run and ride a bike with reasonable economy, but it takes years of practice to be able to swim properly. Therefore, someone who is very inefficient in the water
may be burning more calories per minute than someone who has beautiful technique. Also, experience comes into play. If you are not familiar with swimming, it may feel like you're working extremely hard and burning a lot of calories, but in reality you may only working at a moderate intensity. One more difference with swimming is that if you're monitoring your heart rate, you'll see lower heart rates at given intensity levels, compared with running or cycling. This is due to the physiological response to exercising in a horizontal body position, and in a buoyant environment. The heart can pump more blood easier since it doesn't have to overcome the forces of gravity to distribute it, as it does when you're standing up.

Running: Values are slightly lower than those for swimming since you re not using your upper body muscles to the same degree as while swimming.
