Bielecki, J.W., Pawlicka, E. and Górski, J.: Effect of exhaustive exercise on liver mitochondrial function in the rat. Acta physiol, pol., 1968, 39(5-6): 421-406. The oxidative and phosphorylative function of rat liver mitochondria after exhaustive exercise was investigated. The stimulation of state 4 respiration (without ADP) with NADH and FADH₂ dependent substrates was demonstrated. The reduction in RCR ratio (the rate of oxidation in state 3/the rate of oxidation in state 4) and enhanced activity of oligomycin sensitive ATP-ase was also found. The results suggest an inhibition of liver mitochondrial phosphorylative activity in rats exercised till exhaustion.
