Correlation between maximal Oxygen uptake and Distance Running performance in Children

Maximal Oxygen uptake (VO2 max) is considered the single best indicator of aerobic fitness. However, Direct measurement of VO2 max requires a very well equipped laboratory. And takes a considerable d amount of time. Therefore, field testing such as distance running performance has become a popular method for assessing maximal aerobic power. The purpose of the present study was to study the relationship between direct measurement of VO2 max and running performance during 600 and 1000 m in preadolescent children. The result of this study indicated that the correlation coeffecients between VO2 max & each of 600 m and 1000 m running times were 35 and 50, respectively. Analysis of the data by quartiles of VO2 max showed a significant difference between the uppermost and lowermost quartiles in running performance. Finally multiple regression analysis revealed that the best two variables to predict VO2 max included 1000 m running time and subscapular skinfold thickness
