How to stand up on the surfing board, why doesn't the surf board sink

1. How to stand up on the surfing board

Athletes stand on the surfing plate, or use a water movement that controls the waves such as abdominal plates, Kneeling boards, inflatable rubber pads, rowing rowing, kayaks, etc.No matter which equipment is used, athletes must have high skills and balance ability, and at the same time be good at swimming in the middle and long distances.So how do you stand up on the surfing board in the actual operation?

The surfing movement is the athlete's proling or Kneeling on the surfing plate, and draws the starting point where there is a suitable wave.When the waves are pushing the surfing board to slide, the athletes keep the surfboard standing up in front of the waves, and open the front and back of the legs (usually the balanced legs are in front, control the legs behind).Waves, fast gliding.

2. Why can't the surfing board sink

The root cause is buoyancy.For surfingboards, the value of buoyancy and gravity determines that the surfboard will not sink.

There are two causes of buoyancy:

1. The density of the surfboard itself is less than water. The buoyant caused by the part that is not soaked under the water can offset gravity.

2. The shape of the surfing board determines that it has a larger volume of water (which is related to the slightly rolling of the bottom area and edge), which causes a large buoyancy to offset gravity.If the bottom area of the surfing board is small, there will be no chance to get enough buoyancy.

The pressure is just a manifestation of the effect of the interaction between the surfing board and the seawater, and does not determine the ups and downs of the object.Water's force on surfing boards is buoyancy and not support.If it is supported, it is related to the size of the pressure.
