overtraining syndrome OTS exercise athletes cortisol adrenals Testosterone Testosterone:Cortisol hormones

shared by Nathan Goodyear on 29 Jan 16 - No Cached
  • Alterations in the HPA and hypothalamic-pituitary-gonadal axes with a resultant decrease in testosterone:cortisol ratios have been implicated in OTS. Proinflammatory cytokines are potent activators of the HPA system, which cause release of corticotropin-releasing hormone, adrenocorticotropic hormone, and cortisol. These cytokines suppress testosterone through central inhibition
  • Some have suggested that a decreased testosterone:cortisol ratio can be diagnostic of NFO and/or OTS. However, the ratio represents the physiologic strain of training rather than the athlete’s maladaption to that stress
  • Cortisol (catabolic and anti-inflammatory) is converted to inactive cortisone by 11β-HSD2
  • ...2 more annotations...
  • A prospective study found a clinically significant increase in overnight urinary cortisol:cortisone ratio during a high training load period in triathletes, who subsequently underperformed and reported fatigue
  • It is proposed that cytokines may inhibit 11β-HSD2 activity and result in relative increases in cortisol and, hence, catabolism

    Older article, but good one still on hormones and overtraining.  Look to the Testosterone/Cortisol ratio.  OTS will lead to decreased Testosterone and increased cortisol resulting in chronic catabolic state.

    Interesting clinical report on what is termed the "female athlete triad": menstrual dysfunction i.e. loss of menses is not normal and is the result of reduced "energy availability"; sounds like overtraining syndrome.

    Review of the evidence of OTS versus overreaching.  Academic points about the difference really.  This are both dysfunctional physiologies and they need to be approached the same.

    Over training syndrome and its effects on cortisol, SHBG, and IGF-1; or as they authors call it overreaching.  The study contrasted OR versus basic training.
