Overtraining: Don't Do It.

Exercise-Induced Rhabdomyolysis (EIR)

  • EIR  is a relatively common complication of strenuous exercise.
  • "Our data provide evidence that even moderate intensity (approximately 8 METs) (1) prolonged exercise may cause substantial muscle damage equal to that observed in higher-intensity exercise of the same total workload" (Skenderi et al., 2006)

Compromised Immunity

  • Mild tissue Trauma is normal and beneficial part of training, but overtraining could cause trauma that brings more harm than good.
  • "It has been shown that subsequent to severe tissue trauma, humoral immunity is up-regulated and consequently cellular immunity is suppressed. Since cell-mediated immunity, which protects against viral and many bacterial infections, is now suppressed, an individual experiencing severe bodily trauma is at an increased risk of developing a viral or bacterial infection" (Faist et al., 1996)

Overtraining Syndrome

  • Overtraining impedes recovery, decreases performance, increases the risk for musculoskeletal injuries, and disrupt other bodily systems.
  • In an 8-week mouse model, Chung et., al found, "the overtraining syndrome in the exhaustive exercise group significantly affected the growth curve, inflammation, exercise energy metabolism, and behaviors; these changes can also be observed in athletes" (2021).
