Abstract: FIELD: medicine. SUBSTANCE: method involves applying curative pauses in the situations of training-and-working activity like alternating muscles tension and relaxation in combination with calming and mobilizing breathing exercise complexes. Calming breathing gradually prolongs exhalation until it turns out to become twice as long as inhalation phase which is kept unchanged. Breathing pause is made at the end of exhalation phase. The mobilizing breathing involves elongating inhalation phase and breathing pause in proportional relation. Breathing pause duration is kept one half as long as the inhalation phase duration. Muscle tension-relaxation coordination in combination with the calming and mobilizing breathing exercises are aimed at optimization of excitation-inhibition processes in organism on the background of slowing down these processes under full power supply.
