  Combined effects of caloric
  restriction and branched-chain amino acid supplementation on
  body composition and exercise performance in elite wrestlers.
  International Journal of Sports Medicine.  18(1):47-55, 1997 Jan.
  Twenty-five competitive wrestlers restricted their caloric
  intake (28 kcal.kg-1.day-1) for 19 days, using a hypocaloric
  control (hC, n = 6), hypocaloric high-protein (hHP, n = 7),
  hypocaloric high-branched-chain amino acid (hBCAA, n = 6),
  hypocaloric low-protein (hLP, n = 6) diet to determine the
  effects of caloric
  restriction on body composition and performances versus
  control diet (C, n = 6). Anthropometric parameters (weight, percent body fat)
  and adipose tissue (AT) distribution measured by magnetic resonance imaging
  (MRI) obtained before and after diet, were compared. A significant highest
  body weight loss (-4 kg, p < 0.05) and decrease in the percent of body fat
  (-17.3%, p < 0.05) were observed for subjects of the hBCAA group. Subjects of
  the hBCAA group exhibited a significant reduction (-34.4%, p < 0.05) in
  abdominal visceral adipose tissue (VAT). There was no change in aerobic
  (VO2max) (p > 0.75) and anaerobic capacities (Wingate test) (p > 0.81), and
  in muscular strength (p > 0.82). We conclude that under our experimental
  conditions, the combination of moderate energy restriction
  and BCAA supplementation induced significant and preferential losses of VAT,
  and allowed maintainance of a high level of performance.
