For trained cyclists, the ideal pedaling speed (cadence) for energy efficiency and muscle use is linked to their strength. However, their preferred pedaling speed is more related to their endurance fitness level.

Area of Science:

  • Exercise Physiology
  • Sports Biomechanics
  • Cycling Performance

Background:

  • Understanding optimal pedaling cadence is crucial for cycling efficiency and performance.
  • Individual differences in preferred cadence may reflect varying physiological adaptations.
  • The relationship between strength, endurance, and cadence selection in trained cyclists requires further investigation.

Purpose of the Study:

  • To investigate the association between muscular strength capacity and both preferred and optimal pedaling cadences in well-trained cyclists.
  • To differentiate between energetically optimal cadence (EOC), neuromuscular optimal cadence (NOC), and preferred cadence (FCC).

Main Methods:

  • Eighteen trained cyclists underwent three testing sessions.
  • Evaluated maximal voluntary contraction of lower limbs and performed an incremental test to exhaustion.

  • Conducted a 20-minute submaximal cycling exercise at various cadences, including preferred cadence (FCC), measuring cardiorespiratory and EMG data.

    • Main Results:

    • An energetically optimal cadence (EOC) was identified at 63.5 rpm, distinct from the preferred cadence (FCC) at 90.6 rpm.
    • No significant difference was observed between preferred cadence (FCC) and neuromuscular optimal cadence (NOC) (93.5 rpm).
    • Significant correlations were found between EOC, NOC, and strength capacities (r = -0.75, -0.63), while FCC correlated with VO2max (r = 0.59).

    Conclusions:

    • In trained cyclists, the energetically and neuromuscularly optimal cadences are significantly influenced by lower limb strength capacity.
    • Preferred cadence appears to be more closely associated with an individual's endurance training status (VO2max) rather than strength.
    • These findings suggest distinct physiological underpinnings for preferred versus optimal pedaling cadences in cyclists.
