Chaotic dynamics of cardio intervals parameters in repeated experiments before and after physical exercise
A multiple repetitions of cardio intervals parameters of trained examinee before and after physical exercise have been studied. It has been presented the theory of chaos and self-organization offers new methods which provide calculation of quasi-attractors parameters of state vector behavior of system x(t) in the phase space of states. For all received cardio intervals values the comparative statistical analysis has been made, the areas and volumes of quasi-attractors has been calculated, and also phase portraits where as function (the first coordinate) x1=x1(t) used cardio intervals itself and the second phase coordinate x2=x2(t) =dxi/dt was rate of change of x1(t). Any dosed physical loading leads to reorganization in mechanism of cardio intervals regulation what changes the value of volumes and areas of quasi-attractors, however the received result statistically insignificant.
