This investigation is one of the main studies which can be used to gain a better understanding in the performance enhancement of athletes. Athletes were subjected to hypobaric environment (high altitude) training in order to attain an understanding of both blood lactate levels and heart in endurance ability related performances. Exercise intensity based on the 4mM level determined by blood lactate concentration in hypobaric environment was used as a standard. One set of athletes were examined at 2,000m after one hour stay at 4,000m high altitude and one at a fix level of 2,000m. Athletes performed at differing altitudes produced steady state at lactate equalling 4mM during physical activity. They also gave lower heart rates compared with athletes examined at fix altitudes. Athletes performed at fix altitudes produced fluctuating levels of lactate which increased during exercise. It was concluded that athletes performed at varying high altitudes might be effective to the balance of blood lactate entry and removal, and response of heart rate. Hence it can be seen that this form of training is one of the more beneficial methods for athletes involved with endurance based sports.
