Science Research on ISS Russian Segment

Implementation of the program of scientific experiments of a South-African cosmonaut

CCE Experiment

CCE experiment is included in the scientific program of South African cosmonaut Mark Shuttleworth and is a constituent part of the Russian Program for Implementation of Scientific and Technological Research Planned for the Fourth Manned Expedition ISS-4.


  • 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.


  • 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.

Flight Equipment Used:

  • Out of the aides protecting against effects of zero-gravity:
    - Stationary bicycle VB-3;
    - Expander.
  • Out of the medical monitoring equipment:
    - Sphygmomanometer "Tensoplus";
    - Cardio-recorder 90205.


  • Consumables pack for Cardio-recorder 90205;
  • Saliva-A kit;
  • An accessories kit:
    - dictaphone;
    - batteries for the dictaphone;
    - cassettes;
    - measuring tape;
    - RPE (coefficient) scale.

Expected Results:

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.
