Population
9 professional road cyclists (mean age 26 years; VO2max 72.6 ml/kg/min)
Design

Follow-up
20 minutes
Key result
During constant load heavy exercise, professional cyclists exhibited a small VO2 slow component (130 ml in 17 minutes) without significant changes in neuromuscular activity (P>0.05).

Small VO2 slow component without neuromuscular changes in cyclists warrants caution attributing it to fatigue; leaves open other mechanisms in trained athletes.
Observational (n=9)
In professional cyclists, constant load heavy exercise induces a small VO2 slow component that does not appear to be driven by altered neuromuscular activity.
Lucı́a et al. (2000) conducted an observational in Professional road cyclists (n=9). 20 minute cycle ergometer tests at about 80% of VO2MAX was evaluated on Magnitude of the slow component of oxygen uptake (VO2) and neuromuscular activity (rms-EMG and MPF). During constant load heavy exercise, professional cyclists exhibited a small VO2 slow component (130 ml in 17 minutes) without significant changes in neuromuscular activity (P>0.05).
