Aim: Monitoring of height and weight in children in schools has been discussed to get data on trends in obesity. Physical fitness may be just as important to monitor and a simple reliable test will therefore be important. The aim of this paper was to analyze the association between VO2max measured during maximal work on a treadmill and running distance in an intermittent running test.
Methods: Three different groups conducted an intermittent running test VO2max was measured directly during treadmill running. The groups were 27 physical education students (age 20.0-27.0 years), 57 children (age 9.9-11.0 years), and 14 male elite soccer players (age 14.2-15.0 years).
Results: The reproducibility of the Andersen test was good (r=0.84). Subjects ran 15 m (SD 61 m) longer the second time, but this difference was not significant (P=0.102). The association between running distance in the Andersen test and VO2max measured on the treadmill showed a correlation coefficient of 0.87 in university students, 0.68 in children, and 0.60 in soccer players. For the whole group: VO2max= 18.38 + (0.03301*distance) - (5.92*sex) (boys=0;girls=1) (r=0.84).
Conclusion: The test may provide teachers and health care professionals with an important tool to estimate physical fitness in children and adolescents in a fast, non-expensive and reliable way.
