Monitoring Overload and Regeneration in Cyclists

  • Uwe A. L. Gastmann
  • Manfred J. Lehmann


Training of high-performance athletes is always like a “ride on a razor blade”. A balance of necessary phases of overload and recovery will, in general and if all other conditions are all right, e. g. day form, environmental conditions, etc., lead to good competition results. A training/competition ≫ recovery imbalance, however, will result in performance incompetence and overtraining syndrome.
