Abstract

The extent to which differences between men and women in cardiorespiratory capacity (VO2max), percent fat, and running economy (VO2 in ml/min/kg BW at 188 m/min) account for the sex differences in 12-min run performance was investigated in 34 male and 34 female recreational runners, 19-35 yr of age. Men differed significantly from women in VO2max, percent fat, and 12-min run performance (3294 vs 2747 m), but not in running economy (39.0 vs 39.1 ml/min/kg BW). Simple and multiple regression and correlation analyses indicated that relations of the biological variables to 12-min run performance were similar within groups of men and women. Multiple regression analysis revealed that percent fat, VO2max, and running economy accounted for 74, 20, and 2 of the average sex difference in 12-min run performance, respectively. It was concluded thatfor men and women similarly trained, the average sex difference in 12-min run performance is primarily due to differences in percent fat and cardiorespiratory capacity. If the observed differences between men and women on these variables are truly a function of sex, results of this study provide a biological basis for different distance running performance expectations for men and women.
