Effects of Hydration Changes on Body Composition of Wrestlers

The aim of this study was to determine effects of hydration changes on bioelectrical impedance in wrestlers. One hundred fourteen wrestlers aged 15-17 yr were recruited. The wrestlers’ body composition analysis was determined using the methods of bioelectrical impedance (BIA) and skinfold (SK). Urine specific gravity (Usg) method was used for determining the level of body hydration. According to different hydration status no significant difference was found in the comparison of body composition as determined by BIA (P>0.05). There was a significant difference between the two methods used for the assessment of body fat percentage (BIA %10.4±4.8; SKF % 9.0±5.6) (P<0.05). We may suggest that body hydration fluctuations or dehydration relatively may affect to assess body composition assessment via BIA. This observation may appear to not be appropriate the BIA to determine body composition of wrestlers during dehydration position.
