Physiology and biomechanics have been actively using various methods of statistics for the last 100–150 years. However, N.A. Bernstein – the outstanding biomechanic of the 20th century, put forward the hypothesis of «repetition without repetition» in the organization of movements back in 1948. A year later, W. Weaver - one of the information theory founders, generally proposed to bring all biosystems beyond the limits of deterministic and stochastic science. However, the proof of these two brilliant hypotheses began only 20 years ago. The Eskov-Zinchenko effect was proved, which showed the absence of any samples’ statistical stability of body functions parameters. In particular, this is clearly manifested in the organization of any movements. #CSOC1120.
