The Correlation Between Body Composition And Body Function In Some Elite Winter Athletes

Objective: The objectives were to test the index of body composition, balance ability,maximum oxygen intake (VO2max) and Lung function on elite athletes of Freestyleskiing aerials and Short-Track Speed Skating for describing the feature of bodycomposition and function, and to further explore the relationship between bodycomposition and cardiopulmonary function.Methods:20athletes(8males and12females) of Freestyle skiing aerials and12athletes(7males and females) of Short-Track Speed Skating were recruited assubjects. Body composition, balance ability, VO2max and Lung function weremeasured to analyze the correlations with body composition and cardiopulmonaryfunction.Results:(1) In Freestyle aerials, body fat percentage(PBF) of males and females were13.10±4.82%and21.79±5.38%respectively; Lean body mass(LBM) were50.68±5.40kg and39.29±5.59kg respectively; Wist-to-ratio (WHR) were0.76±0.04and0.72±0.02respectively.(2) In Speed Skating, PBF of males and females were17.04±2.92%and23.16±4.63%respectively; LBM were60.75±3.84kg and44.52±4.80kg respectively; WHR were0.66±0.29and0.59±0.33respectively.(3) PBF of females of Freestyle aerials (21.79±5.38)was significantly higher than thatof middle-distance race （17.92±3.59）， short distance race(16.24±3.01), andgymnastics(10.35±3.10)（P<0.05）；WHR(0.72±0.02) was significantly lower thangymnastics(0.77±0.02)（P<0.05）.(4) In Freestyle aerials, maximal oxygen absolute value of male and female were3.45±0.72L/min and3.19±0.45L/min respectively.(5)In Freestyle aerials, Y axis mobile distance of both legs and right leg in male were200.91±50.95mm and266.81±69.52mm respectively, and X axis mobile distancewere207.32±35.54mm and280.44±64.57mm respectively; Y axis mobile distanceof left leg in female was244.78±57.90mm, and X axis mobile distance was271.97±97.77mm.(6) In males of Speed Skating, pulmonary ventilation volume was16.72±3.11L/min, maximal voluntary ventilation(MVV) was201.55±39.63L/min, tidal volume(TV)was1.07±0.20L; In females of Speed Skating, pulmonary ventilation volume was10.40±2.92L/min, maximal voluntary ventilation(MVV) was136.56±15.66L/min,tidal volume(TV) was0.63±0.09L.(7) In females of Freestyle aerials,there was significantly positive correlation betweenWHR and VO2max absolute value（r=0.879，P<0.05）.(8) In females of Speed Skating, there was significantly positive correlation betweenpulmonary ventilation volume and PBF（r=-0.979，P<0.01）、 Fat weight（r=-0.941，P<0.05）and WHR（r=-0.976，P<0.01）.Conclusions：(1)There are significant differences in body composition in femaleathletes between different sports events in Freestyle aerials.(2) There was significantly correlation between body composition or body shape andcardiopulmonary performance and cardiopulmonary performance may be speculatedform body composition and body shape.(3)There was no significant correlation between body composition andcardiopulmonary performance in males.
