[Mobility of cardiorespiratory system under conditions of tiredness in cycling sprinters and stayers of identical qualification].

The aim of this research work was to determine and to compare the dynamics indices of the mobility function of the cardiorespiratory system (CRS) under different conditions of functioning of the cyclist's organism. The indices of mobility of the CRS functioning at various levels of organism functioning were determined and compared on 24 cyclists- sprinters and stayers in each period of annual cycle (at the end of the transition and comparative periods and at the middle of the competition period). It has been revealed that mobility of the CRS functioning straight away after the limbering-up in the initial stage of physical loading is developed in sprinters more than in stayers. Under conditions of light tiredness especially with increasing of sporting form these differences are leveling. Mobility of the CRS functioning in the process of rehabilitation is developed in stayers in greater degree than in sprinters. After loading under conditions of light tiredness the differences in the indices characterizing mobility of the CRS functioning in the period of rehabilitation with the sporting form growth increase.
