Summary

Overtraining in military recruits is detectable using the free testosterone/cortisol ratio (FTCR). A significant FTCR decline indicates overtraining and reduced physical performance, suggesting FTCR as a monitoring tool.

Area of Science:

  • Sports Medicine
  • Endocrinology
  • Military Physiology

Background:

  • The free testosterone/cortisol ratio (FTCR) has diagnostic relevance for overtraining in athletes.
  • Overtraining criteria include an FTCR below 0.00035 or a 30% decrease.
  • Overtraining incidence in special military units remains unstudied despite demanding training.

Purpose of the Study:

  • To investigate the potential overtraining in Spanish special military unit (GOES) recruits.
  • To analyze the effects of an intense 8-week training program on the FTCR in GOES recruits.

Main Methods:

  • 42 GOES recruits underwent an 8-week intense physical training program.
  • Measurements included hematological and hormonal parameters (FTCR), aerobic/anaerobic tests, and strength/power tests.

  • Data were collected before (PRE) and after (POST) the training program.

    • Main Results:

    • A high incidence of overtraining (23.8%) was observed, defined by a FTCR decline of 30% or more.
    • Overtraining was significantly associated with decreased performance in isometric strength, vertical jump, and Wingate tests.
    • The FTCR proved a sensitive indicator for detecting overtraining in this military population.

    Conclusions:

    • The FTCR can serve as a valuable tool for monitoring exercise training in military units.
    • Monitoring FTCR can help prevent overtraining and maintain optimal performance in military personnel.
    • Combined with performance tests, FTCR offers a comprehensive approach to managing training loads.
