The paper deals with the ergometric endurance criteria in field-and-track middle-distance race and systematizes the applied training means according to the direction (nature) of the physiological effect. The ergometric analysis of 'velocity-time' and 'distance-time' dependences, according to the data of the world race records, allows defining the role of the aerobic and anaerobic energy production at particular distances of the field-and-track race. The level of development of the sportsmen's aerobic and anaerobic capacities affects the manifestation of special endurance in the middle-distance race. The experiment was conducted among field-and-track athletes of high qualification specializing in the middle (800 and 1500 m) distances. The main factor influencing the result in a race is the energy indicators. So, their measurement and estimate serve the main leverage of the training session. The use of predominantly anaerobic exercises during the specialized work-outs significantly improves the runners' special endurance indicators.

The main concept of the study is based on the study of human potential as one of the conditions for the economic security of an enterprise. The article considers the theoretical aspects of human potential, describes the subject of human potential, reveals assessment tools and factors influencing its human development. The most significant potential threats that directly affect the development of human potential are indicated, including: the risk of burnout of employees working remotely, the prevalence of relatively directive management methods at the level of line managers of the enterprise. The ways of overcoming the existing problems are proposed, the solution of which will influence the development of human potential.
