    Experiment Description

    Research Overview
    Information Pending

    To study effects of zero-gravity on human cardiovascular system. Recorded in the course of the experiment is the heart rate of South African cosmonaut at rest or under graduated physical exercise. to study human energy inputs in the course of physical exercise in space flight environment by analyzing water balance in the body.

    Operational Requirements
    Saliva-A kit, dictaphone, cassettes, measuring tape, RPE (coefficient) scale, Stationary bicycle VB-3, Expander out of the medical monitoring equipment, Sphygmomanometer "Tensoplus", Cardio-recorder 90205.

    Operational Protocols
    Comparing the process of heart rate regulation by cosmonaut's vegetative system at rest and during physical exercise in space flight. Reducing the negative effects of space flight on the muscles. Determining cosmonaut's power inputs over a 24-hour period of measurements based on his individual heart rate vs. energy input curve. Determining daily fluctuations of cortisol content in saliva as a function energy inputs.

    Results/More Information
    Obtaining data under a specially designed cosmonaut training program, including pre- and post-flight studies, which allow to develop a new method for evaluating energy inputs during various physical exercises and to update the strategy for cosmonauts' physical training.
