ABSTRACT
Six wrestlers, whose body weights should be reduced 4-11% in relatively short period of time to be acknowledged for intercollegeate 62 kg class competition, were selected and their daily food intakes in regulation, reduction through recovery period of body weights were estimated. Simultaneously, the weights of whole urine and feces were estimated, and some urine components were analysed.<BR>Nutrients intake except calsium and iron were maintained allowance level in regulation period, and reduced through reduction period. On third day of recovery period, the body weights were recovered to their own level, but through the period, only the intake of energy, water, sodium and vitamin A were recovered to the level of regulation period. Personal deviations in their intakes of vitamin B complex and C were distinkt, and the iron intake was under level through all period.<BR>The average body water contents was 68%, estimated by D<SUB>2</SUB>0 method. Negative water and nitrogen balance through regulation and reduction period turned to positive in recovery period, but not completely recovered to their nomal level.
