What is this?
Members stand on surfboards, or use nets, kneeling boards, inflatable rubber pads, rowing boats, kayaks, etc. Ride the wind and waves. No matter what kind of equipment is used, swimmers must have high skills and balance ability, and be good at swimming in the wind and waves.
Take the waves as the power and do it at the stormy seaside. The height of waves should be around 1 m, and the minimum should be not less than 30 cm. Hawaii has suitable waves all year round, especially in winter or spring. There are waves from the North Pacific Ocean, and the waves are as high as 4 meters, allowing athletes to slide on them. Therefore, Hawaii has always been the center of surfing in the world.
The surfboard originally used was about 5 meters long and weighed 50 ~ 60 kilograms. After World War II, foam plastic board appeared and its shape was improved. The surfboard in use now is 1.5 ~ 2.7 meters long, about 60 cm wide and 7 ~ 10 cm thick. The board is light and flat, with narrow front and rear ends, and the tail fin plays a stabilizing role in the back waist. In order to increase friction, the cardboard is also coated with a waxy outer film. The weight of all surfboards is only 1 1 ~ 26kg.
Surfing is that athletes lie down or kneel on the surfboard first, and then row to a place suitable for waves as a starting point. When the waves push the surfboard to slide, the athlete keeps the surfboard in front of the wave peak and stands, and his legs naturally spread back and forth (usually the balance leg is in front and the control leg is in the back), and his knees are slightly flexed to slide quickly along the waves.
What are the benefits of surfing?
1, restore energy and relieve stress.
In any case, if you want to compare high-rise buildings with commercial centers, the sea and beaches are definitely natural places to relieve stress. Otherwise, why do people choose to spend their holidays by the sea? Walking barefoot on the beach can fully relax your body.

When the tide rises and falls, when you soak in the sea or surf, the waves will play a role in your body. Surfing can eliminate the fat on the abdomen, legs and arms, and swing away the excess fat, which has the effect of losing weight.
Surfing is the most suitable thing to find abroad. Running at full speed on land 100 meters will consume about 35 kilocalories, while sliding on the surfboard 100 meters will only consume 28 kilocalories. At first glance, surfing seems to be inferior to running to lose weight. However, you should know that in the high temperature of 32 degrees, if you can't finish running 1000 meters, you will be panting like an ox, and in the cool sea water, you may still feel dissatisfied at 0 meters. Because the colder the water, the more excited you will be, and even tirelessly look for waves. At this time, not only your whole body muscles are consuming energy, but your body will also break down more sugar and fat to supplement calories in order to maintain body temperature.
3, restore the body, strong physique
When you are on the surfboard, you need to keep your head up and turn your head and ski with your arms. These movements are very good for the neck, shoulders and waist, and are very helpful for the functional recovery of the damaged parts. When surfing, in order to keep the balance of the body, tighten the muscles, which will gain the muscles of the back and abdomen. Constantly looking for a balanced position, thus losing the muscles of the thigh.
Even if you can't control it and fall into the water at once, you don't have to worry about spraining your joints. Because at the moment of breaking through the surge, the buoyancy generated by the water will lift people up, and then the load of the body will be evenly distributed throughout the body. The advantage of surfing in summer is that it can greatly reduce the exercise pressure of lower limb joints. On land, every mile we run, each foot will touch the ground about 1000 times. Ankle, knee and thigh joints will shake violently, and muscle sprains or ligament strains often occur. And if you drive a surfboard, the vibration is almost running on land112, which is very harmless.
