Diagnosing overtraining in athletes is challenging. This study suggests the Recovery Stress Questionnaire for Athletes, reaction times, and hormonal responses to exercise can help identify nonfunctional overreaching (NFO) in female speed skaters.

Area of Science:

  • Sports Medicine
  • Exercise Physiology
  • Psychology of Sport

Background:

  • Current diagnosis of overreaching and overtraining relies on exclusion criteria.
  • Objective diagnostic tools are needed to confirm overtraining syndrome in athletes.

Purpose of the Study:

  • To evaluate the effectiveness of four potential diagnostic tools for identifying nonfunctional overreaching (NFO) in female speed skaters.
  • To differentiate between athletes experiencing NFO, recovering from NFO, and healthy controls.

Main Methods:

  • Case study involving three female speed skaters (16-19 years old): one with NFO, one recovering from NFO, and one healthy control.
  • Utilized the Recovery Stress Questionnaire for Athletes (RSQ-A) and the Profile of Mood States (POMS).
  • Assessed reaction time under pressure and hormonal responses (e.g., cortisol) to maximal exercise bouts.

Main Results:

  • The NFO athlete exhibited high stress and low recovery on the RSQ-A, alongside an unfavorable mood profile on the POMS.
  • The recovering athlete showed intermediate stress/recovery levels and a mood profile similar to sedentary individuals.
  • The NFO athlete demonstrated impaired reaction time performance under pressure and an exaggerated hormonal response to exercise.

Conclusions:

  • The RSQ-A, reaction time tests, and hormonal analysis show promise as objective tools for diagnosing NFO.
  • These methods may aid in the early detection and management of overtraining syndrome in young athletes.
