Freestyle, with reasonable action structure, labor-saving and low resistance, is the fastest swimming posture at present. To be specific, even in the whole set of Freestyle movements, leg movements, in addition to propulsion, also play a role in balancing, maintaining the stability and coordination of the body, and making a powerful stroke with both arms. The stroke with both arms can be divided into forward crossing and middleTechnical movements of synchronized swimming

In order to lay tiles on the ground around the pool, use the number of tiles
Suppose the length of the pool is a and the width is B, then m=2 (A-1) +2 (B-1) +8=2 (a+b) +4, so it is: 2 (a+b) +4About swimming
For beginners, generally speaking, due to the limited time to learn swimming, or poor physical coordination and other reasons, sometimes in teaching, when beginners are not proficient in leg movements, they have a complete cooperation practice of breaststroke in order to catch upThe picture on the right is the schematic diagram of the swimming pool to be renovated in the red star hotel. The workers want to wipe every side of it
The location of tiling is actually the bottom and surrounding of the swimming pool. This problem is to calculate the surface area of the swimming pool, and then divide the surface area by the area of a tile. In this way, the number is the number of tiles to be purchased (20+15) two 2+20 15]0.4 0。How does synchronized swimming float on the water
