The purpose of this study was to examine the influence of body fatness, aerobic and anaerobic ability on 3-km running performance in 19 physically active boys (mean +/- SD, age = 10.4 +/- 0.9 yrs). The sum of six skinfolds, VO2 at 8.04 and 9.65 km.hr-1, and VO2max were measured in the laboratory. Run time for 3 km was assessed twice on separate days on a 200-meter indoor track. Prior to each run, every child performed two 55-meter sprints and two vertical jumps. Mean +/- SD values for the sum of skinfolds, %VO2max at each running speed, VO2max and 3-km run time were: 33.9 +/- 14.9 mm; 70.6 +/- 6.6% and 81.0 +/- 7.9%; 54.6 +/- 5.0 ml.kg-1.min-1; 16.41 +/- 2.58 min, respectively. Significant (p < 0.05) correlations were observed between the following variables and run time: sum of skinfolds (r = 0.72); vertical jump (r = 0.67); sprint time (r = 0.59); VO2max (r = 0.61); and, %VO2max at each treadmill speed (r = 0.79 and r = 0.75, respectively). Stepwise multiple regression analysis indicated that the combination of the %VO2max at 8.04 km.hr-1 and vertical jump accounted for 83% (adjusted R2) of the variance in running time (SEE = 1.06 min, p < 0.05). This study suggests that 3-km run time in physically active boys is influenced by aerobic and anaerobic indices as well as body fatness, supporting the notion that children, compared to adults, are not metabolic specialists.
