BACKGROUND: There are various changes in cardiac physiology in athletes compared to the normal population. These physiological changes may differ according to the exercise content. The aim of this study was to compare the effects of different exercise methods on the heart.
METHODS: A total of 122 male athletes from various sports were evaluated. Depending on the sorts of sports, these participants were split into aerobic, mixed, and resistance groups. Each athlete had to meet the inclusion criteria of having participated in the present sport for at least a year and having trained for at least 600 minutes per week over the previous three months. Transthoracic echocardiography was used to investigate the effects of different exercise types.
RESULTS: The aerobic group's heart rate and ejection fraction were found to be lower than those of the resistance and mixed groups (F<inf>(2.105)</inf>=23.487, P=0.001). The end-diastolic thicknesses of the interventricular septum (8.7 SD 0.8 vs. 10.0 SD 0.7), interventricular septum (11.3 SD 0.9 vs. 13.0 SD 0.9), left ventricular posterior wall (8.6 SD 0.7 vs. 9.9 SD 0.8), and interventricular septum (11.1 SD 0.9 vs. 13.3 SD 0.9) were all found to be lower in the aerobic group than in the resistance group (P=0.0001). The effect of resistance exercise on heart rate was not observed as clearly as other groups.
CONCLUSIONS: Resistance exercise has a more dominant effect on ventricular thickness than aerobic exercise. In mixed exercise groups, this increase in thickness is similar to resistance exercise. The content of the training should be considered in the evaluation of the athlete's heart. Identifying the subgroups of the athlete's heart will be useful in the differentiation of pathologies and also in the follow-up of the athletes.
