Moder aerobics iitially was the physical traiig cotets that huma desiged for astroauts to pedal towards outer space. While i the eighties 0th cetury with the globalizatio of iformatio aerobics as a kid of etertaimet ad fitess evet has rapidly developed i the world ad formed ito a fitess craze. People s purst of beauty ad health lets aerobics to go further ad further i the advaced scietific society. The paper researches o Chiese aerobics sports idustry through fuzzy comprehesive evaluatio by fuzzy comprehesive evaluatio value it ca get that Chiese aerobics sports idustry developmet status is good but there are still some room for improvemet with aerobics sports idustry develops Chiese aerobics udertakig will more rapidly develop. Keywords: Aerobics Biomechaics Fuzzy comprehesive evaluatio Fitess effectiveess Sports idustry.. INTRODCTION I 998 iteratioal aerobics league was fouded i the world icluded member states as Russia Swede kraie Britai America Demark Filad Germay Hugary Japa Chia s Taiwa ad so o. til 00 there were 8 coutries orgaizig ad cultivatig aerobics i the world []. Chiese aerobics udertakigs are rapidly developig research o the aspect of aerobics basic mechaics are fewer; the paper carries out mechaical research o aerobics accordig to aerobics difficulty rules util 000 Chia totally published above 000 pieces of aerobics papers ad textbooks as well as works which idicated Chiese research o aerobics was gradually developig ad gradually formed ito system. The paper firstly researches o aerobics udertakig techique of expressio ad actio form i sports techiques as Table show []. Secodly accordig to iteratioal aerobics judgmet criterio aalyze a aerobics athlete or a aerobics team utilize evaluatio model to calculate.. FZZY EVALATION MODEL ESTABLISH- MENTS Fuzzy comprehesive evaluatio model is fit for fuzzy calculatio that multiple factors are ucertai the paper utilizes fuzzy comprehesive evaluatio ad steps are as followig: At first the paper establishes factor set : = ( ) k Secodly it establishes judgmet set V (evaluatio set):the paper establishes fuzzy mappig from judgmet matrix to judgmet matrix V it gets fuzzy relatio as followig matrix shows: R r r r r r r rm rm rm = The paper establishes weight set A= ( a a a ) it meets coditios: i= a = a 0 i Fuzzy relatio R every lie reflects the lie ifluece factors to object judgmet extet ad meawhile R every colum reflects the colum ifluece factors to object judgmet extet. ij i= r j = m Secodly the paper carries out followig calculatio accordig to fuzzy comprehesive evaluatio: i 87-0X/5 05 Betham Ope

Based o above described facts actual chage model that obtais by fuzzy comprehesive evaluatio is as (Fig. ) shows: Fig. (). Chaged model. Accordig to (Fig. ) markig cotets it gets fuzzy comprehesive evaluatio chaged model so that ca establish correspodig every factor grade evaluatio trasformatio fuctio evaluatio factors u u u u u5 membership fuctios ca be expressed as followig formula ()()(): k 0.5( + ) k k k u u ( u ) = 0.5( ) k u < k 0 < k i v i k k k 0.5( ) k k k 0.5( + ) k < k k k uv( u) = k 0.5( ) k < k k k k 0.5( ) < k k 0 k k u u ( u ) = 0.5( ) k u < k i v i k k k 0.5( + ) < k k.. Combie with Fuzzy Evaluatio Model to Evaluate Aerobics Players Aerobics maily focuses o teeagers with the developmet of global competitio teeagers educatio has become key factors. However physique of teeagers that are immersed i study has become key problems with the () () () pheomea multiplies its health coditios become more serious. For aerobics future udertakig developmet physique is more crucial it decides aerobics future developmet i special aerobics educatio places. By above model priciples it establishes factor set from which = ( ). Amog them sports school fitess facilities sports school educators cultivatio sports curriculum orgaizatio cultivatio ad else it gets Table. The paper establishes small factor set amog four importat factors sets. By Table listed factors it gets evaluatio set. { } = u u u u { } = u u u u u 5 { } = u u u { } = u u u u By collectig data ad aalyzig it gets sports school fitess facilities sports school educators cultivatio sports curriculum orgaizatio cultivatio ad else four kids of factors importace rakig statistics as Table show.
