Instrument and method for evaluating land-water force transformation efficiency of aquatic sports athlete

Abstract

The invention relates to an instrument and a method for evaluating land-water force transformation efficiency of an aquatic sports athlete, which belong to the technical field of motion training methods and testing instruments of competitive sports and are used for evaluating the land-water force transformation efficiency of the aquatic sports athlete. The technical scheme is as follows: an on-water traction testing instrument comprises a pulling force sensor, an electric signal conversion circuit board, an isokinetic motor and a computer, wherein one end of the pulling force sensor is connected with a boat through a traction belt, the other end of the pulling force sensor is connected with the isokinetic motor, the electric signal output end of the pulling force sensor is connected with the electric signal conversion circuit board, and the electric signal conversion circuit board is connected with the computer; and an overland rowing testing instrument and the on-water traction testing instrument are used for testing overland force, paddling power, traction force of the boat and traction power of the athlete, the computer is used for calculating the land-water force transformation efficiency of the athlete, and the training process is further evaluated. According to the instrument and the method, disclosed by the invention, the land-water force transformation efficiency of the athlete can be accurately determined, and the blank at home and abroad can be filled up.

Description

technical field [0001] The present invention relates to a test instrument for converting the land power of athletes in water events such as rowing and kayaking into water driving force and a method for evaluating the conversion efficiency of athletes' land-water power by using the instrument, which belongs to The technical field of sports training and testing instruments and methods for competitive sports. Background technique [0002] In the rowing and kayaking events of competitive sports, the strength level of athletes is one of the main factors affecting sports performance. The land-water power conversion efficiency of kayakers has a more direct impact on sports performance. [0003] The strength training of rowing, kayaking and other water sports athletes can be divided into land strength training and water strength training. Land strength training can purposely practice the muscle strength of all parts of the body, especially for the development of maximum muscle str...

AI Technical Summary

Problems solved by technology

At present, the land strength ergometer can only measure the specific strength level of athletes on land, and the specific strength level of athletes in water cannot be accurately measured.

[0006] (2) Blindness of strength training

The blindness of strength training is mainly manifested in the fact that there are different stages of transformation from landing strength quality to water strength, how to accurately determine the different transformation stages and transformation effects of individual athletes, there are no definite means and instruments at present

[0007] (3) The relationship between specific strength and sports performance is uncertain

Athletes' specific strength, especially the correlation coefficient between specific strength in water and performance, is the theoretical basis for determining strength training goals. However, due to the particularity of water events, there is currently no means to accurately measure specific strength in water.

[0008] (4) Since the conversion efficiency of the athlete's land-water force cannot be accurately determined, it is difficult to determine the training direction of the athlete, that is, the relationship between strength training and technical improvement. This is a problem that plagues many coaches. Judgment based on the personal experience of the staff, which has a large blindness

[0009] (5) There is no water traction test instrument for water sports athletes

At present, there are only relevant land-based special strength test instruments for the strength test instruments of water sports athletes at home and abroad, such as isokinetic strength tester (C0N-TREX), rowing ergometer (CONCEPTⅡ), kayak ergometer (KAYAKPYO) ), etc., but there is no water traction testing equipment for water sports athletes, so there is no research on the land-water special power conversion of water sports athletes so far
