The study involves 10 males and 10 females, totaling 20 subjects. Since the VO2max is measured before and after the program, a repeated measures ANOVA would be appropriate, which typically involves calculating three F-ratios: one for the main effect of time, one for the main effect of gender, and one for the interaction between time and gender.
