AB  - Effects of different cycling cadences (revolutions/min [rpm]) on metabolic rate, 
      blood lactate concentration (BLC), and reliance on carbohydrate (CHO) defined as 
      the fraction of oxygen uptake used for CHO oxidation (relCHO) are highly 
      individual. Whether this depends on the individually maximal achievable rpm 
      obtained at minimized cycling resistance (rpm(max)) is unknown. The authors 
      tested the hypotheses that the individual freely chosen rpm in an incremental 
      cycle-ergometer test (ILT) and relCHO at given BLC levels both depend on 
      rpm(max). Seven master cyclists and 8 not specifically trained leisure athletes 
      performed an ILT at individually freely chosen rpm and an rpm(max) test. 
      Respiratory data and BLC were measured; relCHO was plotted as a function of the 
      BLC for the determinations of the individual BLC at relCHO of 75% and 95% (BLC75% 
      and BLC95%). With 16.7%, the between-subjects variability of individual rpm was 
      high but independent from rpm(max). In the master athletes, rpm(max) explained 
      59.3% and 95.2% of BLC75% (P = .043) and BLC95% (P = .001), respectively. 
      Irrespective of cycling experience, the individually preferred average rpm at 
      submaximal stages of an ILT is highly variable and independent of rpm(max). In 
      experienced cyclists, carbohydrate management defined as the ratio between 
      substrate availability as indicated by BLC and relCHO depends on rpm(max).
