title: New and old in pediatric exercise physiology.
abstract: Researchers in pediatric exercise physiology sometimes overlook previously published findings that are similar, or even identical, to their own. The intent of this review is to provide examples for the above pattern. These examples relate to the following topics: 1) is the O2 uptake plateau a necessary criterion for the establishment of maximal O2 uptake in children? 2) children's greater utilization of fat during prolonged exercise, 3) children's lower maximal blood lactate levels, 4) the higher metabolic energy cost of locomotion in children and the possible causes for this phenomenon, and 5) the lower cardiac output and stroke volume in children, at any given O2 uptake.
