Area of Science:

  • Sports Science and Exercise Physiology
  • Endocrinology
  • Human Physiology

Background:

  • Understanding seasonal hormonal and body composition changes is crucial for optimizing training in elite athletes.
  • Salivary cortisol and testosterone levels can reflect training load and physiological adaptation.
  • Lean body mass is a key indicator of fitness and performance in endurance athletes.

Purpose of the Study:

  • To investigate seasonal variations in salivary cortisol and testosterone in highly trained male cyclists.
  • To examine the relationship between these hormonal changes and fluctuations in lean body mass.
  • To assess changes in physical fitness parameters over a competitive season.

Main Methods:

  • Evaluated 7 male cyclists at the start and end of their competitive season (6 months apart).

  • Assessed physical fitness, including maximal oxygen consumption (VO2max) and workload (Wmax), and ventilatory thresholds.
  • Measured salivary testosterone and cortisol, body composition (6 skinfolds), and anaerobic capacity (maximal accumulated O2 deficit).

    • Main Results:

    • A significant increase in several aerobic capacity parameters was observed.
    • The study identified seasonal variations in salivary cortisol and testosterone levels.
    • Correlations between hormonal changes and lean body mass variations were explored.

    Conclusions:

    • Highly trained cyclists exhibit significant changes in physical fitness and aerobic capacity during a competitive season.
    • Seasonal fluctuations in salivary hormones (cortisol, testosterone) and lean body mass occur in these athletes.
    • Further research is needed to fully elucidate the complex interplay between hormonal status, body composition, and performance adaptations in cyclists.
