The thesis investigated a method of determining accumulated oxygen deficit (AOD) in children and quantified the anaerobic performance of children in a variety of ways. The first of the studies investigated the developmental profile of anaerobic performance using AOD in three groups of
male children classified as pre-pubertal, pubertal or post-pubertal. The second study investigated the potential differences in the oxygen uptake when discrete and continuous incremental submaximal protocols were used to determine the relationship between submaximal oxygen uptake and exercise intensity. This second study also aimed to
investigate the repeatability of oxygen uptake during continuous incremental submaximal exercise. Study Three compared AOD of pre-pubertal males using running and cycling as the modes of exercise.
