Purpose: The research examined the effect of exercise training intervention in aorta and pulmonary artery flow velocity. Methods： Twenty-three healthy university male-student (mean age 20.3±1.6 years, height 174±5.2 cm, weight 72.1±12.4 kg) were randomly assigned to exercise group (E group, 11 males) and control group (C group, 12 males). The exercise training intensity was 75% of VO(subscript 2max) running and the duration time was 45 minutes, three days per week. The resistant training was two days per week, two sets and 12-15 repetitions recommended by ACSM. The C group maintained their life-style. Magnetic resonance imaging and the CV flow analyzer are used to measure velocity of aorta's and pulmonary artery's CV flow. Subjects underwent all tests at baseline and after one year training period. The data were analyzed by mixed two-way ANOVA to examine any change after exercise training. The statistical significance was determined at α=.05. Results： In aorta, there were significant differences in average value caliber velocity of flow's peak (75.0±9.8 vs. 68.4±8.8 cm/s), slowest value caliber velocity of flow's mean (55.8±14.4 vs. 66.1±20.0 cm/s), slowest value caliber velocity of flow's valley (19.5±5.9 vs. 26.1±8.3 cm/s), quickest value caliber velocity of flow's mean (31.2±13.9 vs. 52.2±41.1 cm/s), quickest caliber velocity of flow's peak value (90.6±51.5 vs. 125.1±56.1 cm/s). In pulmonary artery, there were significant differences in slowest value caliber velocity of flow's mean (28.8±8.9 vs. 46.9±12.3 cm/s), slowest value caliber velocity of flow's valley (10.0±6.5 vs. 19.5±6.0 cm/s). Conclusions： We concluded that aorta's and the pulmonary artery's CV flow velocity were unchanged during rest after one year exercise training intervention.
