The article considers a method of analysis of the results of the study by the method of functional biomechanical tests. Encouraged to undertake an analysis on the basis of the reduced sample data, which is considered the informative part of the received signal. Analysis is suggested on the basis of interpolation polynomials. As basic features to consider the interpolation polynomial of Lagrange and interpolation polynomial Gauss. Determination of the coefficients of interpolation polynomials is based on a matrix representation of the decomposition of vectors of a polynomial in approximation and further application of the obtained matrix. Discusses the application of the method of analysis on the example of the results of studies by the method of functional biomechanical tests. Provide an assessment of the accuracy of the approximation for the entire curve interpolation polynomial of Lagrange and interpolation polynomial of Gauss. It is revealed that for the analyzed signal type interpolation polynomial Gauss gives a lower level of absolute error of approximation.
