[Optimization of directed training loads on the respiratory system].

Potentiality of an increased elastic resistance to respiratory movements in improving the functional conditioning of young athletes was evaluated. Training with increased elastic resistance to respiration brought about gains in strength and endurance of the respiratory muscles, growth of the maximal oxygen consumption, work ability, and special physical fitness of athletes.

[The effect of sensory stimuli of varying modality on the human body functioning and indices of tense muscular activity].

The work had a purpose to study benefits of aromatic blends of tonic and relaxing essences and functional music on some of the psychophysiological properties of the human functional state and motor activeity. Participants were 30 sprinters (18-22 y.o. males) having the first-class and master ranks. The psychophysiological indices of the athletes' functional state were evaluated with the use of the "CAH" and Spilberger situational anxiety tests, calculated Cardeu vegetative index, time for simple motor reaction and reaction to a moving object. Motor activity was evaluated by top running speed determined with a photo-electronic time-keeper and by duration of pedaling on bicycle ergometer at maximal power. The running step parameters were recorded with electropodography. It was shown that the positive effect of the aromatic essence blends and functional music on motor activity developed fairly rapidly but did not last long. The article discusses features and possible ways the aromatic blends and music effect human organism.

[Specifics of bio-controlled training in directed relaxation].

Studies of personal and general patterns of acquisition of skills in biocontrolled relaxation based on biological feedback (EMG) permitted classification of human subjects by the ability to relax voluntarily muscles. In the process of skill acquisition changes were minimal at the beginning, grew progressively further on and stabilized on completion of the course of training.

Results of training in directed relaxation were assessed based on the principle of biological feedback (BF). The psychophysiological status and balance of the key sympathetic control pathways were shown to undergo changes in the course of training.
