תקציר	Lactate threshold, also termed the onset of blood lactate accumulation (OBLA), is the exercise intensity at which blood lactate concentration increases rapidly and non-linearly. Initially defined by Klaus Wasserman in 1973, the concept describes the physiological transition from aerobic to anaerobic metabolism. As exercise intensity increases, lactate production and clearance remain balanced until a critical threshold is exceeded, after which lactate rapidly accumulates in the blood, signaling a shift toward anaerobic energy pathways. This parameter is crucial in endurance sports and clinical exercise assessment.	VO2 max represents the maximum amount of oxygen a person can utilize during intense exercise, measured in millilitres of oxygen per kilogram of body weight per minute (ml/kg/min). Developed by Robert Bruce in 1963, the Bruce Protocol is a graded maximal exercise test on a motorized treadmill that incrementally increases speed and incline until the subject reaches volitional exhaustion. This test is a gold standard in clinical and sports medicine for assessing cardiorespiratory fitness and aerobic capacity.
