Sports speed allocation optimization model research and application in marathon competition

Zhiqiang Cai, Weiguo Li, Binfei Bai

By consulting document literature, adopt survey and logistic analysis; make research on 117 athletes of master sportsmen and sportswomen competition speed allocation. Research result shows that athletesÂ’ first, second, third, fourth, fifth phase performance is higher thanwhole journey running average performance, the seventh, eighth phase performance is in the reduction trend, competition speed allocation is in constant speed running, athletesÂ’ competition process each phase speed percentage overall differences is small and has the same feature, which builds theoretical basis for establishing competition each phase performance quantization mode, adopt formula: target performance*phase speed percentage=competition whole journey each phase ideal performance, establish men athlete competition performance 2:05:00-2:20:000women competition performance 2:15:00-2:30:00 each phase performance quantization mode table that is each phase speed allocation table, suggest coaches, athletes to apply established mode comparing competition implementation ideal speed monitoring and allocation, and provide references for creating excellent results.
