title: [Relation of human weight loss to the duration of space flight].
abstract: A formula describing weight losses in the first approximation during space mission was derived assuming that humans may adapt to space flight effects. The process depended on two parameters one of which characterized maximum body losses and another--time of adaptation. Weight estimates of Skylab crewmembers obtained with the aid of the formula were in good agreement with actual results. The typical time of adaptation was two days. Possible ways of constructing a more precise model of weight changes and its use to diagnose the status of crewmembers are discussed.
