The meaning of swimming pool? Why must there be deep water
Buoyancy does not change, but resistance decreases. Specifically, water waves generated by water will propagate down to the bottom of the pool and then reflect back. It will produce resistance to people. The deeper the water, the smaller the resistance and the longer the time. This is why the standard swimming pool for international competitions has reached a water depth of 3 metersHow does the depth of the swimming pool affect swimming
This is called backward compatibility. However, according to the regulations, a deep-water certificate is required for swimming in deep watercourses, and many swimming pools do not need a deep-water certificate at alDeep water swimming  but resistance will decreasel. Although the buoyancy in shDeep water swimming  but resistance will decreaseallow water and deep water does not change, the resistance will decrease. Specifically, the water wave generated by pumping will be transmitted down to the bottom of the pool, and then reflected back, causing resistance to people. The deeper the water isWhy does it take more effort to swim in a deep pool than in a shallow one
There is always a sinking feeling in the diving area. Swimming in deep water is easier and faster than swimming in shallow water. Because the deep water area is deep, the disturbance reflected by the bottom of the pool is small, and the water wave resistance is small, while the shallow water area is the opposite. Therefore, this tired "feeling" may be that you unconsciously swim faster and output more strengthWhy can't you swim in deep water
