objective: (1) Differences between the effects of circuit and fartlek training method on VO2Max; (2) Differences between the effects of high and low peak expiratory flow on VO2Max; and (3) The interactions between circuit, fartlek exercise methods and peak expiratory flow (high and low) on VO2Max. 2 x 2 factorial method. Peak expiratory flow instruments: peak flow meter and VO2Max: multistage fitness test. ANAVA data analysis α = 0.05. Results. (1) There is a significant difference between the effects of circuit and fartlek exercise methods on VO2Max, p value = 0.022 < 0.05, which show that circuit training method is objectively better than fartlek training method. (2) There is a significant difference between the effects of high and low peak expiratory flow on VO2Max, p value = 0.000 < 0.05, students with high expiratory volume achive higher value than those with low expiratory volume. (3) There is a significant interaction between circuit and fartlek training method and (high and low) peak expiratory flow on VO2Max, p value = 0.000 < 0.05
