Effect of distance feedback on pacing strategy and perceived exertion during cycling

Article Abstract:

A study was conducted in order to examine whether giving incorrect distance feedback would result in altering the pacing strategies, perceived exertion and heart rate during the 20-km cycling time trials (TT). The results suggest that the exercise performance and pacing strategy are not affected by feeding incorrect distance feedback during a 20-km cycling TT.

Athletes with exercise-associated fatigue have abnormally short muscle DNA telomeres

Article Abstract:

Results reveal that endurance athletes, exhibiting fatigued athlete myopathic syndrome (FAMS), possess shorter telomere lengths of DNA than those of control group athletes. Data indicate that skeletal muscle from FAMS athletes undergoes extensive regeneration resulting from frequent satellite cell proliferation cycles induced by muscle damage.

Regulation of pacing strategies during successive 4-km time trials

Article Abstract:

Athletes adopt a pacing strategy to delay fatigue and optimize athletic performance. Whether alterations in muscle recruitment by the central nervous system could explain the observed pacing strategies is described.
