[An expert system for controlling the physical training program of crews on long-term space missions].

The concept of in-flight expert system for controlling (ESC) the physical training program during extended, including Martian, space missions has been developed based on the literature dedicated to the microgravity countermeasures and a retrospective analysis of effectiveness of the known ESC methods. This concept and the principle of crew autonomy were used as prime assumptions for defining the structure of ESC-based training in long-duration and planetary missions.

[Comparative analysis of the informational merits of ergometric and functional indicators of work capacity].

Informational merits of ergometric and routine functional indices (MPK, anaerobic threshold--AT, PWC170) were compared by testing performance of 20 young males with high levels of fitness. Criterion for work ability was maximum time of rowing ergometer with incremental loading and two tests with permanent load in the regions of submaximum (about 7 W/kg) and high (about 4 W/kg) loading. Ergometric indices, i.e. individual limits of relative power, were calculated from Muller's equation tlim = eb x W-a. Before, during, and after 5-20 minutes of test session gas exchange, pulse rate, and blood lactate were measured to calculate MPK, AT and PWC170, and oxygen demand fraction. Ergometric indices were found to be no less informative in evaluation of work ability than the common indices involving determination of gas exchange, PR and lactate. Ergometric and functional indices showed high correlation. It was stated that none of the indices can be equally informative regarding all types of work ability testing. Application of two-increment test and subsequent calculation using Muller's equation allows to get around the principle of uncertainty according to which none of the test can be at one and the same time used to assess power and capacity of energy systems of the skeletal muscles. Besides, ergometric tests provide reliable enough characteristics of work ability without resort to expensive and bulky equipment.

[Effect of single and systematically repeated physical exercise on the threshold of anaerobic metabolism].

The anerobic threshold (AT) has been defined in 37 healthy young subjects and adults after single and repeated exercises close to the threshold one as regards the intensity. Single exercise lasted 1.5--2 h, whereas repeated ones 7 days to 5 months. The AT has been found to drop significantly at single exercises and to increase at systematic exercises lasting 30 days and more.

[Health-promoting technologies of the 21st century: realities and prospects].

The paper outlines present-day progress and prospects of new-generation health-promoting technologies by automatic control over physical condition and by drawing up individual health-promoting physical exercises and elaborating a basically new approach to evaluating the physical condition of each specific human being with regard to the naturally different qualities of individuals in the population. The authors propose a family of computer-aided diagnostically recommended expert systems which provide not only new possibilities of improving physical education, but can be used in solving other tasks of health-promotion.
