In the hot summer, the most comfortable way to cool down is to play in the swimming pool or the beach. You can cool off the heat and quench your thirst and exercise.
When you go out for a swim, you must bring your own whale goggles.
There are many whale goggles on the market, with different prices and different brands, which make people look dazzled.
I hope that through my own actual measurement, I can help you choose suitable and easy-to-use whale goggles. The prices of the 7 whale goggles are all around 100 yuan, and they are also the most popular styles on a certain treasure in their respective flagship stores.
I will start from the five dimensions of comfort (wearing comfort, weight), practicality (waterproof, fogging), UV resistance, workmanship (appearance value, outer packaging), and price. I measured 7 models of these 7 different brands. Whale goggles.
Among them, the comfort is based on my personal feelings, and each person’s situation is different for reference only.
Underwater breaststroke standards and norms refer to this study and practice
There are many types of whale goggles and breaststroke, and the technique is the most complicated. There are wave frogs, flat frogs, high-flying styles, semi-high-flying styles, etc. Of course, there are also leisure frogs and head-up frogs. To say that the mainstream competitive frog is now the wave frog. Breaststroke is easy to learn, but difficult to learn well. There are too many detailed movements. Many swimmers like breaststroke but always feel that their technique is not standard. Let’s talk about this breaststroke with you today!
Step 1: Stroke outwards, straighten your elbows, turn your palms from downwards to outwards, and extend your arms out while turning your palms. During the entire stroke, the hands must be stretched forward with yin force. When the hands are stretched forward, the body will be stretched, the width of the shoulders will be narrowed, and the streamlined shape will be strengthened to make the water more draining. Sweep outwards to push the water to both sides, there is no forward propulsion force, all actions without propulsion force do not exert force, waste physical energy. It can be seen that when the hands complete the outward stroke, the elbows are still straight, and the distance between the hands is very wide, and the shoulders are about one foot extended. Common mistakes: bent elbows, blocking water. Struggling hard, wasting energy, and creating waves. Even though the waves are small, it will have an impact on the 0.01-second match.
The second step: catching water, high elbow catching, is the key to the propulsion of catching water. Common mistakes: sinking elbows to catch water and dragging elbows to catch water are common problems in self-learning breaststrokes. The wrists of this kind of breaststroke must be bent. Catch the water too early and catch the water before reaching the catching position, which will shorten the distance of stroke inward.
The third step: stroke inwards and push backwards when catching the water. Everyone knows that there is propulsion. When you stroke inward, hold the forearms with your hands inward and push the water inward to push your upper body up and keep your body in position. The high position can reduce resistance and help the speed of kicking water. When this action is completed, the elbows are under the armpit and close to the chest to reduce water resistance. Amateur swimmers don't need to stroke inward, because it is always a motion that is not propelled. If it is used, it will consume a lot of physical energy. Common mistake: Many people do not use the stroke because this inward movement has no propulsion, which makes the body position too low.
The fourth step: stretch your hands forward, quickly stretch your hands forward, straighten your elbows, and then stretch forward with yin force after straightening, lengthen the upper body, narrow the width of the shoulders, and create a streamlined shape. When the hand is stretched forward, the palm turns from upward to inward and then downward. The forward movement must be carried out in the water, and the palms and fingers should be straightened, and the hands should be streamlined in the water as soon as possible to break the water. Common mistakes: Some people see the Olympic gold medals show up when their hands are stretched forward, and they follow suit. However, because of their immense strength and high body position, their hands will be exposed to the surface of the water, and you...? Don't follow it, after all, the water out of your hands when you stretch out will reduce the streamline.
The first step: retract the legs and relax the ankles of the amateur swimmer. There is no propulsive force when the leg is retracted, so remember not to use force. When retracting the legs, the knees should not be separated and do not need to be clamped. When the legs are retracted, the angle between the thighs and the body is about 120° to 140°. When the legs are closed, the soles of the feet must be as close to the hips as possible to increase the kicking distance. Common mistakes: When retracting the legs, the feet are turned upside down, and the water is pushed forward to reduce the speed. The more the thigh is retracted forward, the greater the resistance, and when the leg is retracted, the water pushes forward, sending the person backward, slowing down the speed, and even stopping in severe cases.
Step 2: Turn the toe board and lift the toe board with the toes facing outward. The distance between the knees is about the same as the width of the shoulders. If the knee joint is stiff, the distance between the knees should be extended according to the actual situation. It is necessary to know that the wider the distance between the knees, the more water is blocked. When the legs are retracted, the legs must be fully retracted to increase the kick distance. Common mistake: Many people stretch their knees a long way, which is very water-blocking, and some people can't learn to turn the toeboard.
The third step: kick the water, kick the water to the back of the body. Common mistakes: It is wrong to kick up or down. Kick up. When kicking, the person sinks down and then floats up. Kick down to push the person up and weaken the propulsion. A breaststroke foot that is not kicked backwards will definitely not move forward.
Step 4: Continue to kick the water. When you kick the water until your knees are straight, your feet are almost as wide as your shoulders. The feet of this frame are still reversed. Amateurs must note that this is a professional swimming technique, and most people don’t. It's easy to control, don't care about it, usually amateur swimmers will straighten their feet early, just ignore it. Common mistake: Many people straighten their knees too early, and even kick their feet outside. This kind of mistake is slow because the kicking force is lost outwards, and it is easy to kick people, frogs feet. It hurts to kick someone.
Step 5: Put your feet together and put your feet together. Amateurs don't need to straighten the feet, just relax the feet. Remember that I am an amateur swimmer, it is impossible to compare with Olympic-level swimmers, otherwise it may be counterproductive. Common mistakes: Many lazy people don’t straighten their feet together. Even after kicking, they think they can save effort, but in fact they waste more energy because of water blocking.
