TI  - The effect of acute fluid consumption following exercise-induced fluid loss on 
      hydration status, percent body fat, and minimum wrestling weight in wrestlers.

AB  - Acute fluid consumption (approximately 1 L) has been shown to reduce urine 
      specific gravity (Usg) among subjects after an overnight fast, yet it is unknown 
      if Usg may be reduced among subjects who have experienced exercise-induced fluid 
      loss. The purpose of this study was to examine the effect of acute fluid 
      consumption on Usg, body mass, percent body fat (%BF), and minimum wrestling 
      weight (MWW) following an exercise-induced fluid loss protocol. National 
      Collegiate Athletic Association coaches' perceptions of the weight certification 
      program (WCP) were also evaluated. Twelve men wrestlers (19.8 +/- 1.14 years) were 
      tested prepractice (PRE), postpractice (POST), and 1 hour after consuming 1 L of 
      water (PFC). Percent body fat was measured by skinfolds (SF), air displacement 
      plethysmography (ADP), and multifrequency and leg-to-leg bioelectrical impedance 
      analysis to calculate MWW. Urine specific gravity measurements significantly 
      increased above PRE (1.013 +/- 0.006) at the POST (1.019 +/- 0.007; p = 0.017) and 
      PFC (1.022 +/- 0.008; p = 0.025) assessments; however, POST and PFC were not 
      significantly different (p = 0.978) from one another. The %BF values were similar 
      (p > 0.05) at each assessment point when using SF and ADP. When compared with 
      PRE, MWW significantly reduced at the POST assessment when using SF (67.2 +/- 8.4 
      vs. 65.7 +/- 8.2 kg; p < 0.001) and ADP (66.6 +/- 9.1 vs. 64.8 +/- 9.0 kg; p = 0.001), 
      reflecting the reduction in body mass observed after exercise. Forty-seven 
      National Collegiate Athletic Association coaches completed the questionnaire and 
      2 central themes emerged: (a) concerns with the 1.5% weight loss plan and (b) 
      wrestlers using strategies in an attempt to circumvent the WCP. Exercise-induced 
      fluid loss followed by acute fluid consumption equal to 1 L was ineffective in 
      reducing Usg.
