AB  - This study examined the methods used to meet certification weight for wrestling 
      and to measure the changes in body composition during 1 season for Division III 
      college wrestlers. Nine college wrestlers completed this study. Body composition 
      was analyzed by underwater weighing (UWW) and multifrequency bioelectrical 
      impedance before and throughout the competitive season. Hydration status was 
      measured by urine osmolality (Uosm) and urine specific gravity (Usg). Nutritional 
      intake was measured for 2 1-week periods, once at the beginning and again near 
      the end of the season. Subjects' fat-free mass (FFM) increased an average of 1.8 
      kg, whereas fat mass (FM) decreased 2.2 kg as indicated by UWW from the beginning 
      to the end of the season. Wrestlers on average cycled their weight 3.4 kg (4.7% 
      of body weight) per week. The majority of wrestlers cut weight by reducing 
      calories and restricting fluids starting 2 days before the competition. Uosm and 
      body weights on Friday suggested that for wrestlers to achieve the necessary 
      weight loss by dehydration to "make weight" for a Saturday meet, wrestlers would 
      approach a 5% level of dehydration. No loss of FFM because of weight cycling (WC) 
      was evident to achieve competitive weight. Most wrestlers significantly 
      restricted fluids and caloric intake in the 48 hours before weigh-in.
