New and old in pediatric exercise physiology

Researchers in pediatric exercise physiology sometimes overlook previously published findings that are similar, or even identical, to their own. The i ntent of this review is to provide examples for the above pattern, These ex amples relate to the following topics: 1) is the O-2 uptake plateau a neces sary criterion for the establishment of maximal O-2 uptake in children? 2) children's greater utilization of fat during prolonged exercise, 3) childre n'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 O- 2 uptake.
