[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.

[Indices of immune reactivity of sportsmen organism after one time physical load of different intensity and duration].

The aim of this research was to determine and to compare the indices of immune reactivity of sportsmen during one time physical load of different intensity and duration. Observation was carried out on 15 wrestlers of average qualification during the annual cycle after three one time physical loadings of different intensity and duration (15 sec.-maximum intensity; 60 sec.
