FIELD: medicine.
SUBSTANCE: invention relates to a method for determining the effectiveness of an athlete’s respiratory movements when performing exercises with a weight or weights. When executing the method, the specified parameters of the athlete’s movement and breathing are recorded and assessed using a hardware and software complex. The researcher and/or athlete selects the athlete’s testing program from the program library of the hardware and software complex. The complex comprises: a signal recorder with a specified number of sensors, a device for displaying graphic information. The sensors are designed to be fixed in specified places on the athlete’s body and record the movement and acceleration of the athlete’s body in space, as well as the athlete’s breathing parameters. Display devices are monitors and/or projectors that show the researcher and/or athlete at a given distance graphs of periodic changes in the longitudinal and vertical components of the acceleration of the athlete’s body, as well as breathing capacity and volumetric velocity of the air flow of breathing, during the exercise or additionally, in specified testing modes showing the execution time of the exercise and/or the number of lifts of the sports equipment. Respiratory parameters are recorded using a spirograph or pneumotachograph. The signal graphs are processed by a computer program. Then the frequency spectra of these signals are converted into graphs. The efficiency of the athlete’s respiratory movements is calculated using graph processing with a computer program. In this case, the breathing capacity synchrony coefficient is calculated as the ratio of the peak frequency of the breathing capacity to the peak frequency of the longitudinal component of the body acceleration. The synchrony coefficient of the volumetric air flow velocity is calculated as the ratio of the peak frequency of the air flow velocity during the athlete’s breathing to the peak frequency of the vertical component of the body acceleration. The efficiency coefficient of respiratory movements is calculated as the product of the synchrony coefficients of synchrony coefficient and volumetric air flow velocity, and the effective range of coefficient values when an athlete performs exercises with a weight or weights tends to unity in the range of 0.76-1.00.
EFFECT: assessment of the athlete's breathing is provided, taking into account the coordination of respiratory movements with motor actions in weight lifting using the frequency spectra of breathing indicators and body movement.
