Fast (n = 50) and slow (n = 49) performers were selected from a convenience sample (n = 125) at a small, Midwestern university based on performance of two 40-yd dash trials. Subjects were also measured for vertical jump (VJ), standing long jump (SLJ), Margaria-Kalamen stair run power (M-K), isometric leg strength (ILS), skinfold-predicted %fat, and thigh cross-sectional area (CSA). Stepwise discriminant analysis selected SLJ, VJ, and CSA, in that order, to differentiate fast and slow performers (canonical correlation = 0.70). The unstandardized discriminant function correctly categorized 84% of the slow performers and 82% of the fast performers. The analysis indicated that greater SLJ, higher VJ, and smaller CSA were associated with faster 40-yd dash performance in untrained college women.
