Traditional methods to normalize aerobic fitness (VO2max) have been considered inadequate for not properly adjusting the effects of body size in children, adolescents and adults. Allometric scaling (Y=aXb) has emerged as an efficient method to compare individuals of different body dimensions. Studies aimed to compare VO2max in individuals with different body sizes should use methodology that properly accounts for the body size effect, thereby avoiding misinterpretation and reaching the potentially wrong conclusion. The use of allometric scaling for studies aimed to compare aerobic fitness in children and adolescents who dramatically vary in body size is strongly recommended.
