Biomechanical analysis-based aerobics athletes' athletic ability fuzzy comprehensive evaluation

摘要

The paper firstly applies Lagrange equations to solve restricted particle kinetic equations, combines with theoretical formulas to analyze athlete hand jointmechanicalmovement, and combineswith shoulder joint, elbow joint mechanical analysis to study on aerobics taking-off, rotation and other motions. Establish fuzzy comprehensive evaluation model, define weights, and then establish fuzzy relation matrix, finally calculate. Result shows that aerobics cooperative ability occupies 30%, innovation attainment occupies 25%, and aesthetic level occupies 18%.Among them, cooperative ability, innovation attainment, and aesthetic level belong to humanistic education and cultivation range, the paper can clearly get that aerobics such event is a kind of sports discipline with stronger cultural atmosphere.
