butterflyCorrect posture for butterfly strokeThe arm movements are divided into three stages: pulling and pushing and water out of the water in the pulling stageCorrect posture for butterfly strokePull your arms downCorrect posture for butterfly stroke, palms face downward, arms straighten during the pushing stage, arms push outward, palms face outward, arms bend during the water stage, arms push upward, palms face upward, arms straighten during the water stage, arms should be stretched as far as possible, in order to push the body out of the water body posture in the upper body out of the butterfly stroke, body posture is very important. Correct body posture can be used.
First, the arms are gently inserted into the water on the extension line of the shoulders in the order of the elbow joints of the hands, forearms, upper arms, and elbows, keeping the shoulders relaxed to avoid pressing the arms. After the hands enter the water, the butterfly swimmer's head and shoulders are positioned lower than the elbow joints. With the inertia of the body forward, the arms are separated outward, and then the hands are hooked to hold the water. At the same time, the elbow is slightly lifted. The shoulder strap muscles are stretched. At this time, the distance between the hands is the largest, forming an ideal water holding posture. The forearms are at an angle of about 45 ° to the water surface. Start paddling.
When the legs continue to move up, the thighs begin to press down, and the knee joint presses down with the thighs, and the movement bends naturally. The thighs continue to accelerate downward. As the degree of knee bending increases, when the feet are lifted close to the water, the hips drop to the lowest point. When the knees are bent at an angle of approximately 110 to 130 degrees, the feet are lifted up to the highest point, and the water is accurately drawn downward and rearward. 3-arm posture The stroke of the butterfly arm is the main factor in generating propulsion, and compared with other postures.
Butterfly prone position, the body swings in a wavy dolphin style. The head and shoulders fluctuate with the waves, emphasizing the coordinated efforts of the trunk. The range of action is large. The breaststroke Breaststroke prone position, the body remains relatively horizontal. When retracting the legs, the hips are slightly higher than the head. The movement is highly cyclical, emphasizing the symmetrical cooperation of kick and paddle. The 2-arm movement backstroke alternating stroke with one arm alternating stroke backwards, similar to the reverse movement of freestyle.
3 Correct water holding posture. Water holding posture. Both palms and palms face obliquely downward and stroke outwards to be as wide as shoulder to shoulder. Then high elbows hold the water in your arms and push the water and kick are connected. When the arms accelerate backward and push the water, your legs are ready to go. When the push is about to be completed, your legs are ready to go. When the push is about to be completed, your legs are forced downward to draw water. Keep the continuity of the movement and relax when you retract the legs. When you retract the legs, your thighs are close together but you cannot clamp them tightly. There will naturally be gaps in your calves, which will be natural when you draw water downward.
Butterfly leg movements are very important, and most of the wrong postures are irregular leg movements.Correct posture for butterfly strokeWe will talk about the present later. Let's talk about the correct butterfly leg movement, which consists of two parts: upward kick and downward kick. Upward kick. 1 The legs are naturally close together, the heels are slightly separated into an "inner 8", and the feet are at the lowest point, straighten the knees, lift the hips up to the water, bend the hips to about 160 degrees, 2 straighten the legs and swing upward, and gradually swing the hips.
How to swim the butterfly is as follows: 1 Carry out correct arm movements The arm movements of the butterfly stroke can be broken down into three parts: Pull back. At the beginning, your arms are spread over the top of your head as wide as your shoulders, pull your hand towards your body, and do a semicircular motion, while the palm is facing out and remember that your elbows are always higher than your palms. This is the pulling motion. At the end of the pulling motion, start pushing your palms backwards in the water, along.
7 Long-term training In addition to mastering the correct skills and postures, long-term training is also the key to improving the efficiency of slow butterfly. Through continuous training, the body gradually adapts and improves its technical quality and physical fitness, thereby reducing energy consumption and improving efficiency. Characteristics of butterfly stroke 1 Its core movement is the word "butterfly", which means that the arms circle to both sides at the same time, allowing the body to fly on the water like a butterfly. 2 It is difficult to breathe. Butterfly stroke should be all swimming strokes.
Modern butterfly stroke refers to the basic movement of dolphin swimming. When the arms enter the water and are separated outward, the palms turn sideways, and then turn sideways to downward for paddling. At this time, the high elbow posture is maintained to allow the hands and forearms to form a better water position., and start to paddle from front to back and from outside to inside. When the paddle reaches the bottom of the abdomen, the elbow joint bends to the maximum. The hands are very close to each other and then push the water backwards and outwards to end the paddling movement of the arms with both hands on both sides of the thighs.
2. Master the butterfly breathing skills. The coordination of breathing and stroke is the key to the butterfly stroke technique. When the arm ends the stroke inward, the head is out of the water to inhale. When the arm is moved, the head is restored to enter the water. Remember the "two before", that is, the head is in the hand. Out of the water before entering the water, enter the water before entering the water with the hand. Pay attention to the butterfly stroke body posture and whip kick. It is difficult to master the body posture of the butterfly stroke. It is necessary to maintain the horizontal position and stability of the body. Whipping is the main source of butterfly stroke propulsion. It requires a quick and powerful swing of the legs up and down to form.
1 When entering the water, bend the elbow slightly, slightly higher than the forearm, with the palm facing downwards, and enter the water at an angle of about 45 ° to the horizontal. Then drive the forearm and the upper arm to enter the water accordingly. 2 After holding the water and completing the entry, the arm rotates outwards, the palm gradually turns backwards, and the direction of movement of the hand gradually changes outwards and then backwards and then downwards to hold the water. 3 After completing the hold, while the forearm is externally rotated, the movement of the arms is gradually increased, and the arms are slowly rowed to the water.
3 Arm moving posture After paddling out of the water, the arm is driven by the shoulder to move the arm forward through the air. When preparing to enter the water, the arm is usually moved forward from both sides in a low, flat and relaxed posture. 4 Body posture and whip kick body posture. Butterfly stroke body posture is relatively difficult to master. It is necessary to maintain a certain undulating shape and whip kick the legs at the same time to coordinate efforts to perform whip kick to provide motivation for advancement. 5 Coordination of limbs.
Mastering the correct posture in the butterfly stroke can also help you swim further. The body posture of the butterfly stroke is different from other swimming strokes. It has no fixed body position. The relative positions of the trunk and the head constantly change with each other during swimming. The head and trunk are sometimes exposed to the water and sometimes submerged into the water, forming a wave-like change in position. Generally, after the two-leg movements are over, the two arms are straightened and slid forward is a preliminary posture. At this time, the body must be completely straightened, almost in the water.
1 From the start and the first stroke after each turn, the body must be in a prone position, and the shoulders must be parallel to the water surface. However, the legs are allowed to hit sideways under the water surface. The body must not be turned over into a tilted position at any time. Back down 2 The arms must be swung forward on the water surface at the same time, while paddling backwards underwater. 3 The kicking movements of both legs must be consistent at the same time. Both legs or feet may not be on the same level, but no alternating movements are allowed.
8 Dog-crawl swimming with arms and legs straight, propelled by rapid sweeping of the legs, is one of the most primitive swimming styles 9 Diving swimming Dive from a platform or a height into the water, quickly change to either swimming position and continue forward 10 Bath-style swimming Suitable for beginners or swimmers, treading water with both legs and paddling in the water to simulate swimming in a bathtub.
