Brief Summary

Sports training aims to enhance an athlete's performance (overcompensation). To do that, the athlete must go through periods of fatigue and lower performance (overreaching). When the training plan is balanced, this fatigue is short and reversible.If the training load is too heavy or if recuperation periods are too short, it can lead to persistence fatigue that may only be reversible in the long term. This state of fatigue is part of the broader clinical picture of overtraining, which includes stark changes in performance as well as mood and sleep disorders. Many prediction and characterization methods based on biological markers have been evaluated, but they have not been put into practice in sports training due to obstacles such as reliability, interindividual variability and high costs. This study aims to evaluate a new approach based on the variability of an individual's heart rate (RR variability), which is a way of measuring autonomic nervous system (ASN) activity. It is non-invasive, low-cost, and has already proven useful in athlete health monitoring.

Outcome Measures

Primary Outcomes (2)

  • Autonomic nervous system (ANS) activity

    This ANS is mesured during the night using a spectral analysis of nocturnal heart rate variability.

    One year

  • Fatigue and physical training

    Fatigue and physical training potetially due to overtraining, suspected based on a very significant, long-term worsening in performance

    One year

Secondary Outcomes (5)

  • kinetic of the ANS activity

    Every 15 days (from the iclusion to one year)

  • orthostasis test

    Every 15 days (from inclusion to one year)

  • French Society of Sports Medicine questionnaire

    Every 15 days (from inclusion to one year)

  • POMS (Profile of Mood States) questionnaire

    Every 3 months (from inclusion to inclusion)

  • Sleep quality questionnaire

    Every 3 months (from inclusion to one year)

Study Arms (1)
