TI  - Estimation of Body Fat Percentage in Jockeys: Implications for a Weight Category 
      Sport.
PG  - 511-525
AB  - The assessment of body composition in horse racing, a unique weight-restricted 
      sport, provides an important health and performance indicator. The accuracy of 
      skinfold prediction equations at estimating % body fat (% BF) was compared with 
      dual-energy X-ray absorptiometry (DXA) data in a group of professional Irish 
      jockeys (age 27.5 +/- 7.7 years). Body composition was assessed in seventy-two male 
      professional jockeys (flat n=35 and national hunt n=37) using standardised 
      guidelines for skinfold thickness at 8 sites and DXA body fat assessment. 
      Hydration status was assessed using urine specific gravity (Usg) to determine if 
      participants were euhydrated and male specific prediction equations (Durnin and 
      Womersley, Evans, Lohman, Reilly, Withers and Zemski) were selected to estimate % 
      BF. Jockey-group specific equations were developed using the collected dataset. 
      The selected equations underestimated % BF with variability between equations 
      ranging from 7% to 10% compared to the DXA % BF of 15%. Flat jockeys were 
      significantly lighter and shorter (p < 0.05) compared to national hunt jockeys 
      resulting in the need for individual jockey-specific equations. The Flat and 
      National Hunt Jockey specific equations demonstrated overall agreement accounting 
      for 84% and 83% variance, respectively. Caution must be taken when using existing 
      prediction equations due to the variability of % BF relative to DXA. 
      Jockey-specific equations offer an alternative method for interpreting estimated 
      body fat %.
