Aim: In order to obtain new insight into physiological indicators of performance, the aim of this study was to analyze the relationship between freely chosen cadence (FCC) heart rate (HR) and power output (PO) profiles in members of professional and non professional cycling teams during an incremental test. Method: Heterogeneous group of 26 male cyclists performed a 10W/30sec incremental test on cycloergometer (SRM Training Systems, Jülich, Germany) until exhaustion and FCC - HR ratio vs PO was measured. Results: In all subjects the FCC/HR vs PO obtained showed a linear phase followed by a curvilinear phase starting at comparable FCC/HR value in all subjects (0,62 ± 0,06 SD; ES: 0,01, IC95%: 0,60 - 0,65, IC99%: 0.59 - 0.65). Conclusion: According to some preliminary observations carried out in our laboratory, we hypothesize that the observed deflection point can be related to the anaerobic threshold, but this hypothesis deserves future investigation.
