Description
Technical Field
The invention belongs to the field of sports equipment, and particularly relates to a free swimming land trainer.
Background
Free swimming is one of swimming match items, and is a swimming gesture in which arms move from the water surface to cut water under water and the two arms continuously and alternately perform. The swimming speed of the athlete is mainly 85 percent of the total thrust provided by the upper limb stroke, and the difference between the swimming speed of the legging and the swimming speed of the non-legging is only about 10 percent. Therefore, the paddling of the two arms is very important for the achievement of the free swimming, and the two arms can be matched with the turning body to better complete the technical action.
From the freestyle teaching, freestyle motions are divided into freeplay arm motions and freestyle body rotation motions. Free swimming arm motion: 1) entering water: after the arms move in the air, the big arms rotate inwards, the fingers stretch straight and naturally gather together, and the palm is naturally inserted into the water towards the oblique lower part outside in the posture of high elbow and low hand; 2) carrying out water holding: after the palm center begins to change from the oblique direction to the oblique direction, gradually bending the elbow and the wrist, wherein the elbow is always higher than the arm; 3) paddling: the arms rotate in coordination with the shoulders, the big arms rotate inwards to drive the small arms, the bent arms gradually straighten the thighs to paddle water, the palm center is changed from the lower part in the oblique direction to the upper part in the oblique direction, and the thighs paddle water from bottom to top; 4) water outlet: the palm center turns to the thigh, the fingers firstly draw the water surface upwards, the elbow is slightly bent, the arms are relaxed, the big arm drives the small arm, the elbow part is lifted upwards, the palm center turns to the upper back, and the whole water outlet process needs to be coherent, quick and uninterrupted; 5) moving the arm in the air: the elbow is in a lifting state, the elbow is higher than the arm at the moment, the arm is moved towards the front of the body, the hand feels the action of inserting water, and the preparation of the next water-entering action is carried out; the action of free-swimming body rotation: from the beginning of the water holding action, the body rotates along with the water holding action to the arm on the water holding side until the body rotates to the maximum angle (19.7 degrees for men and 24 degrees for women) when the water outlet action is finished, and then the body rotates to the horizontal position along with the action of moving the arm in the air.
At present, in the free swimming training, the land standing position and the body inclined position in water are adopted for decomposition exercise, and the exercises are too abstract and have poor effect in the early learning stage or when the technical action is improved. The prior disclosed land swimming simulator can not achieve good action shaping of standard arm-drawing action and muscle memory training of standard arm-drawing action because of the lack of specific tracks for free swimming stroke which can not correct action and complete the cooperation of hand-drawing and body-turning.
Free swimming and breaststroke are two most commonly used swimming postures of mass swimming body building, different from breaststroke, land arm bending training of free swimming teaching is more abstract and unintelligible, arm technology and exercise are particularly important for the free swimming training, but no auxiliary instrument for better improving the technical action of the free swimming arm is provided for beginners or sports enthusiasts, and particularly for swimming teaching, the cooperation of free swimming arm bending teaching and turning is a difficult point in the free swimming teaching.
