The Multidimensional Structure of Physical Fitness: Invariance over Gender and Age.
Marsh, Herbert W.
The present investigation extends the factor analytic approach pioneered by Fleishman (1964), incorporating subsequent developments in the application of confirmatory factor analysis and the physical fitness literature (e.g., an emphasis on maximum oxygen intake). More specifically, the ability of an a priori factor structure of physical fitness to fit (i.e., account for) data from the 1985 Australian Health and Fitness Survey based on 25 indicators of fitness (field exercises, technical measures, and laboratory measures) is tested for 2,817 boys and girls aged 9, 12, and 15. An 8-factor model derived from previous research fit the data well for each of the 6 age/gender groups considered separately. Based on tests of factorial invariance, factor loadings and factor correlations were reasonably invariant across the six groups. This substantively important finding indicates that all 25 indicators were equally valid for boys and girls aged 9, 12, and 15. The results provided clear support for the multidimensionality of physical fitness and call into question attempts to summarize fitness with a single indicator (e.g., aerobic power) or a total score representing different components of physical fitness.
