METHOD FOR PREDICTING THE GROWTH OF PROFESSIONAL SKILL IN BALLET ARTISTS Russian patent published in 2006 - IPC A61B5/456 A61B5/91 

FIELD: medicine, sports medicine.

SUBSTANCE: one should study the values for variability of cardiac rhythm at detecting standard deviation against mean arithmetic duration of the next R-R intervals per period of investigation (SDNN) and/or square root out of mean sum of differences squares between the next R-R intervals (r-MSSD) and/or spirography at detecting mean volumetric rate of output (MVR 25-75%) and/or calculating Tiffno's index determined as the ratio of forced expiratory volume (FEV)/sec (FEV1) to vital capacity (VC): (VC)-(FEV1/VC). In case of decreased SDNN value being below 100 msec and/or r-MSSD value being below 80 msec, and/or increased MVR 25-75% up to 120% and more against due value and/or decreased Tiffno's index being below 70% one should consider the prediction for the growth of professional skills of future ballet's artists to be unfavorable. The innovation provides an opportunity for objective prediction of skill growth based upon accurate quantitative criteria reflecting interaction between tonicity of autonomic nervous system and parasympathetic department of regulation against physical adaptation abilities of the body.

EFFECT: higher accuracy of prediction.
