N2 - © 2015, Pleiades Publishing, Inc.The effect of exhaustive weightlifting exercise (WE) on the time-related changes in performance capacity was studied along with measuring several physiological and biochemical variables during exercise. The work performed decreased soon after the start of exercise and stabilized after reducing the amount of weight used (40-10% 1RM). The maximal amplitude of the surface electromyogram (EMG) of m. rectus femori strongly tended to increase in the first half of WE and stabilized at the end of WE. WE substantially increased the blood plasma lactate level, the myoglobin concentration grew twice as high, while creatine kinase (CK) activity remained unchanged. It was assumed to explain the observed decrease in performance capacity that fast motor units (MUs) progressively refuse to work, while weaker intermediate and slow MUs continue working. Unchanged CK activity and an insignificant increase in plasma myoglobin suggested only minor, if any, WE-induced damage to myocyte membranes in
