Shot throwing technique to performance influence T test based on mathematical statistics

Zhiqiang Zhao

The paper more deeply understands spinning technique application in shot throwing by experiment and data handling. By analyzing, it finds spinning shot putting technique relative conforms to shot movement basic principle and rules. Its lengthening on apparatus accelerated speed distance, motions continuity and fluency, full of rhythm, enlarging on apparatus achieved prior speed and other techniques showthat it is current relative advanced shot throwing technique. Spinning technique requires athletesmore coordinate and sensitive, but it doesnÂ’t have high requirement of athletesÂ’ height and weight as well as other indicators, according to Chinese athletes their own features, strength features and better flexibility, coordination and sense of balance, it carries out comparative research on back sliding type and spinning type by data analysis
