[Changes in the body weight of cosmonauts during a 140-day space flight].

During 140-day space flight body mass changes of the Commander and Flight-Engineer were measured. No correlation between body mass losses and flight duration was found. Greatest body mass losses occurred on MD 44--59 in Commander (2.

[Apparatus for medico-physiologic studies of the functional state and work capacity of civil aviation pilots].

It has now become possible to study the functional state of the pilots and to appraise their performance capacity by using a complex set of equipment. During the pilot's operation this equipment provides for obtaining electrocardiograms, information on the heart rate, respiration rate, maximum arterial pressure measured on the finger, skin temperature at 4 points, ambient temperature, taking electromyograms, registering dermato-galvanic reactions after Tarkhanov and the rate of the reaction in response to light and sound. In addition to the mentioned data it is also possible to study during off-duty time the electroencephalogram in 2 leads, arterial pressure after Korotkov, dynamogram, critical fusion frequency, as well as data on the coordination of movements and thresholds of audio-sensitivity.
