Swimming is not only a good means to exercise, but also a life-saving skill. Swimming is also welcomed by more and more people because of its special properties. But before learning to swim, we still need to know the characteristics of swimming.
1. The resistance in water is 12 times that on land. In water, our bodies need to fully accept water, and we need to overcome the resistance in water to do work, so it takes more energy to do work in water at the same distance than on land. According to relevant research, the resistance of human body in water is 12 times that on land.
At the same time, because we are in the water, we need to keep our body on a horizontal plane, and my body needs to be in motion at all times. In this way, we need to overcome the resistance in the water at all times, which will lead to the need to consume heat when swimming and to exercise far above the road.
Second, the heat transfer performance of water is much stronger than that of air. In other words, in order to maintain the normal temperature of the body, our body consumes more calories in water than in air. Relevant experiments show that the energy consumed by standing in water at 12 degree for 4 minutes is the same as that consumed on land at 1 hour under the same conditions.
So swimming is a very suitable exercise to lose weight, which can consume more calories in the shortest time.
3. Swimming can reduce the harm of exercise to the body. Because we need to overcome the self-respect of the human body, it is inevitable that we will affect some parts of our body through injury. In the water, we are floating on the water, which can completely avoid this situation.
So swimming is not only an efficient way to lose weight, but also the safest fitness exercise.
