Summary Relationships between functional anaerobic indicators and the character of cellular muscle energy metabolism were studied. Twelve untrained male students were tested by a specific anaerobic test on the treadmill. The mean values of the anaerobic test were as follows: blood lactate 10.69 mmol · 1−1, running speed 16.08 km · h−1 and duration 92.67 s. The average distribution of muscle fibres (m. vastus lateralis) was: type I 52.2%, type II A 29.0% and type II B 18.8%. The mean enzyme activity values were: triosephosphate dehydrogenase (TPDH) 4.67 Μkat · g−1 w.w., lactate dehydrogenase (LDH) 5.76 Μkat · g−1 w.w, citrate synthase (CS) 0.21 Μkat · g−1 w.w. and hydroxyacyl-CoA dehydrogenase (HAD) 0.12 Μkat · g−1 w.w. Significant negative correlations were found between δLA and CS (r=0.64) and % of fibre type II B and CS (r=0.78) and positive correlations between % of fibre type I and CS and/or HAD (r=0.60 andr=0.62, respectively).
