title: Age differences in human skeletal muscle fatigue during high-intensity intermittent exercise.
abstract: It has been shown at similar relative work rates that children have higher resistance to fatigue than adults during repeated bouts of high-intensity exercise. This age-related difference in fatigue resistance may be explained by factors including muscle mass, muscle morphology, energy metabolism and neuromuscular activation.
  
  
  CONCLUSIONS
  During high-intensity intermittent exercise, recovery periods play an important role in limiting fatigue. Age-related differences in fatigue resistance could also be explained by differences in the rates of resynthesis of some energetic substrates and the rates of removal of various muscle metabolites.
