Why is the freestyle so tired?
Many people in the study of freestyle will feel compared to other swimming posture, freestyle to a more strenuous, in fact, this situation is mostly because of freestyle or posture is not correct, the main reasons are shown in the following aspects.
Breathing is not in place: hypoxia caused.
Action is not relaxed: not in place, swimming too tight, no open action.
The body has no balance: the legs and hips sink, and in the course of the swim you have to kick your legs to make your legs and hips. Breathing ventilation When the head is not well controlled: in the air when the concentration of attention and head, the head under pressure into the water, just leave half the eyes and half mouth out of the water to breathe on the line, if not the problem of ventilation skills, that is the problem of physical strength. When your hands are holding water, be ready to breathe. The head is the side turn ventilation, not to change head.
Once the head is out of water, do not exhale and inhale with a large mouth.
Water resistance: When swimming, the forearm will begin to form a vertical position as far as possible in the head.
The secret of long swim without tired One, the breath, the stroke, the proportion of the leg, the main role of freestyle kick is to balance the body, followed by part of the power. Freestyle kicks balance the body and can reduce a lot of resistance.
Long and freestyle, it is recommended to use breathing: stroke: The proportion of the leg, 1:1:4 (or 1:1:2). Two, the position of the hand stroke, the freestyle stroke position is divided into: before, in, after. Pre-stroke: 1 o'clock position (strong directional position, easy to keep straight line); Middle scribe: 3 o'clock Position (the direction of the position is not strong, not easy to maintain a straight line); after-stroke: 5 o'clock position (poor orientation).
For long distance travel freestyle, it is recommended to use the front stroke position. Three, the stroke route, freestyle strokes can be divided into: linear (J-shaped), curved (C-shaped, s-shaped).
For long distance freestyle, it is recommended to use a curved shape (s shape). Four, breathing frequency, long-distance swimming freestyle should not be used (breathing, paddling, beating legs) 1:2:6 proportion, this proportion is easy to hold your breath (hypoxia).
For long distance freestyle, it is recommended to use a breath frequency set of actions (1 breaths)/1.5~2.0 seconds.
The action Essentials of Freestyle
1, a ghostly glide To master the timing of the two arms, the body must first in the water to maintain a good balance. Maintaining the momentum balance between the end of an arm's stroke and the beginning of the other's arm can help the athlete get a sense of the ability to ' travel ' in the water, gliding without a trace in the water, ghostly and effortlessly.
Momentum retention coupled with a good streamline is the best way to overcome resistance.
2, head, shoulder position, body rotation and streamline The position of the head is very important. The position of the head is higher, so that the torso and legs are easily sunk, resulting in an increase in face resistance. The lower head position causes the hip to rise, and the whole body and the horizontal line, so that the gentle and meticulous water is filled under the body and around the freedom to pass. The posture of the shoulder also plays a great role in streamlining. A slightly upward shrug of the shoulders makes the chest and abdomen flat, creating a smooth, streamlined surface that allows the water to pass smoothly.
A slightly shrugged shoulder also increases the movement of the muscles around the shoulder, making the arm's contractile muscles more advantageous in the mechanical position, making the strokes more powerful.
3, Kick The key to easy and efficient leg kicking is to loosen the ankle. If you can feel the water flowing through the feet of the toes, it means that the ankle is relaxed, two feet soft alternately water. At a fast speed, this operation becomes a powerful whip-like water, maintains the balance of the body, and quickly whips within the body section. As long as the rhythm and balance are unaffected, the way to kick is free to choose.
The modern excellent swimmer's technology is no longer as single as in the past, but shows the characteristic of each other.
4, high elbow position The position of the elbow plays an important role in the underwater stroke stage. The elbow must not be lower than the hand and shoulder, and the first half of the stroke cannot exceed the hand.
Otherwise, the propulsion force is reduced and the hands and forearms are not reacting to the resistance of the water.
5, speed up the stroke. The arm must be accelerated during the stroke, otherwise it is futile and will hardly produce a real propulsion force. When the arm is pushing backwards, the other hand is entering the water at a relatively slow speed and adjusting the hands to prepare for the next stroke.
The arm in the water is slightly slower to avoid damaging the power generated by the other arm's stroke. How not tired of freestyle slimming? It's good to master the action.
