This study examined the effects of exercise training intervention on the left ventricular structure and function. Twenty-four males (mean age 20.4±1.7 years, height 174±5.3 cm, weight 72.0±12.5 kg) were randomly assigned to exercise (B) and control (C) groups. The magnetic resonance imaging was used to measure the end diastolic and systolic left ventricular mass, left ventricular wall thickness, end diastolic volume, end systolic volume, stroke volume, cardiac output, ejection fraction, peak ejection rate and peak filling rate. The cardiovascular endurance was assessed by Sensor Medics 2900 combination treadmill. Subjects underwent all tests at baseline after one-year training. 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 control group maintained their life-style. The result showed that Group B was significantly higher than group C in end-diastolic left ventricular mass (98.7±4.0g vs. 85.8±3.8 g, p＜.05) and end-systolic left ventricular mass (126.3±3.2 vs. 113.8±3.0 g, p＜.05). Group E was significantly higher than group C in left ventricular wall thickness (posterior of apex: 8.1±0.6 vs. 6.0±0.6 mm, septum of apex: 7.7±0.5 vs. 6.1±0.5 mm, and septum of medial: 7.7±0.5 vs. 6.7±0.4 mm p＜.05). However, there was no significant difference in end-diastolic volumes, end-systolic volumes, stroke volume, cardio output, ejection fraction, peak ejection rate, and peak filling rate (p＞.05) between the two groups. Group E was significantly higher than group C in maximal oxygen uptake (57.0±1.7 vs. 47.8±1.7 ml•kg^(-1)•min^(-1) and 4.0±0.1 vs. 3.6±0.1, L•min^(-1), p＜.05). It was concluded that there were significant improvements on cardiovascular endurance, left ventricular mass, left ventricular wall thickness but no effects on the left ventricular function after exercise training.
