Swimming has absolute advantages in improving cardiopulmonary endurance. Swimming requires more breathing and heart pumping ability. In the process of continuous exercise, improve vital capacity and heart function. Running is good for relieving depression. Psychologists' research shows that the cause of depression is the lack of hormones in brain neurons. Hormones increase during running, and the secretion of hormones can also increase after running, so running can eliminate people's depression.

For the same distance, swimming needs more energy than running. Because the resistance of water is greater than that of air, and the faster the speed, the greater the resistance, and at the same time, more heat is needed to maintain the body temperature in water, because the heat loss rate of water is faster than that of air, and the lower the water temperature, the faster the loss rate and the greater the heat consumption. Swimming can relieve the pressure on the waist and knees. These two joints are most likely to be damaged by overweight people. The swimming posture determines that these joints do not need to be impacted by the ground. Running will greatly increase the pressure on these two joints. Swimming has little side effects, and unscientific running is easy to get hurt. But running is simple, you can run at any time, and swimming needs to find a place first, wash and change clothes when you arrive, wash after swimming, and swim once, which wastes too much non-sports time. Compared with running, the shaping effect of swimming is more obvious, and the figure obtained through swimming exercise is more symmetrical. Of course, jogging is also a good way to lose weight. When people exercise in water, all organs participate in it, which consumes a lot of energy, accelerates blood circulation and provides more nutrition for sports organs. The acceleration of blood speed will increase the load on the heart, make the heart beat faster and contract strongly. People who swim regularly have excellent heart function.

Whether running or swimming is a form of exercise, even if there is no condition to swim or run, doing aerobic squats and push-ups in situ can also play a role in losing weight. Losing weight is not a form of exercise, but whether you have the heart and action to lose weight.
