Problems of social, medical, economic, psychological and pedagogical nature related to human disability and processes of their rehabilitation have always been relevant in the society. The purpose of the study was to determine the level of physical working capacity of skilled orienteers with hearing impairments. According to analysis of the dynamics of heart rate and running speed on competitive distances, high performance of orienteers mostly correspond to steadier mean values of pulse and running speed. Pulse curves were rather flat with small fluctuations associated mainly with reaching the checkpoint, registering and leaving it. Thus, as revealed in a series of investigations, orienteers with hearing impairments had a fairly high correlation between running speed and heart rate during competitive activity. It is especially evident when passing lowland parts of the distance. An increase in heart rate was observed when dealing with inclines, water-logged grounds and ploughed fields. Heart rate decreased when descending, stopping or slowing down while reaching a checkpoint and registering on it. The required level of physical working capacity of skilled orienteers with hearing impairments is ensured by high resource indicators of the oxygen transport system. The indicators of maximum oxygen consumption of the leading Russian orienteers with hearing impairments are at the level of 66-71 and 55-60 ml/min/kg for men and women respectively, the speed at the anaerobic threshold is 4.8-4.9 m/s and 3.9-4.1 m/s for men and women respectively, which is slightly different from the indicators of elite orienteers.
