Abstract

We evaluated the effects of 7-day rapid weight loss (RWL) intervention on body composition and biomarkers of creatine metabolism in eight elite judokas during a pre-competition period. RWL induced a significant drop in weight (81.7 ± 10.7 kg at baseline vs. 76.8 ± 10.3 kg at follow-up; P < 0.001), fat mass (12.6 ± 5.6 kg vs. 9.2 ± 4.0 kg; P = 0.003) and fat-free mass (69.1 ± 7.3 kg vs. 67.6 ± 7.7 kg; P = 0.05), accompanied by an increase in serum creatinine levels at follow up (104.0 ± 10.5 µmol/L vs. 114.9 ± 10.2 µmol/L; P = 0.009). An acute restriction of food and fluid intake appears to negatively affects fat-free mass and indices of kidney function in judokas.
