Freestyle swimming land trainer

Abstract

The invention provides a freestyle swimming land trainer; rotary supporting devices are arranged on a base in parallel, and a front lying plate and a rear lying plate are arranged on the rotary supporting devices respectively; a motor transmission device drives the rotary supporting devices to drive the front lying plate and the rear lying plate to rotate left and right; each rotary supporting device drives a rotary rod through a rotary wheel to push a rotary supporting rod to move up and down in a limiting groove drum, and the rotary supporting rods drive the front lying plate and the rear lying plate to rotate left and right; telescopic guide rails are arranged on the two sides of the front lying plate, pulleys are arranged in the telescopic guide rails, and gloves and pull wires are connected to the pulleys; a wind resistance device and a pull wire rod are arranged at one end of the base, and a rotating speed sensor is arranged in the wind resistance device; a driving wheel is arranged on a rotating shaft of a wind impeller; a pull wire wheel is arranged on the pull wire rod, pull wires on the pulleys bypass the pull wire wheel, and the transmission wheel is connected into a tension sensor to be connected with an elastic pull wire. According to the invention, the optimal underwater arm scratching action teaching training can be truly simulated, and the matching data of scratching arms and rotating bodies is collected to facilitate teaching.

Description

technical field [0001] The invention belongs to the field of sports equipment, in particular to a freestyle land training device. Background technique [0002] Freestyle is one of the swimming competitions. Freestyle is a swimming style in which the arms move from the surface of the water to stroke underwater, and the two arms are constantly alternated. The swimming speed of an athlete mainly provides 85% of the total thrust through upper body strokes, and the difference in swimming speed between kicking and non-kicking is only about 10%. Therefore, the stroke of the two arms is very important for the performance of freestyle swimming. At the same time, the two arms need to cooperate with the turning to better complete the technical movements. [0003] From freestyle teaching, we can know that freestyle movements are divided into freestyle arm movements and freestyle body rotation movements. Freestyle arm movements: 1) Entering the water: After the arm moves in the air, th...

AI Technical Summary

Problems solved by technology

[0004] At present, in the freestyle training, the standing position on land and the inclining position in the water are used for decomposing exercises. In the early stage of learning or when improving technical movements, these exercises are too abstract and the effect is not good

The existing open land swimming simulator, because it does not have a specific track for the freestyle stroke, cannot correct the action well and complete the cooperation of the stroker and the turn, and cannot reach the action stereotypes and standards of a good standard arm stroke action. Arm stroke muscle memory training

[0005] Freestyle and breaststroke are two of the most commonly used swimming styles for public swimming and fitness. Unlike breaststroke, the land-curved arm training in freestyle teaching is more abstract and difficult to understand. Arm technique and practice are particularly important for freestyle training, but for beginners For scholars or sports enthusiasts, there is no better auxiliary equipment for improving freestyle arm stroke technique, especially for swimming teaching, the coordination of freestyle curved arm stroke teaching and turning is a difficult point in freestyle teaching
