Aerobic training has been reported to have a positive effect on myocardial performance index. The aim of the present study was to examine the myocardial performance index (MPI) in sprinters and endurance athletes.
A total of 66 elite male athletes (36 sprinter and 30 endurance athletes) and 33 agematched sedentary controls voluntarily participated in the study. The echocardiographic evaluation was performed and TEI index was measured as a marker of myocardial performance index in all groups.
Demographic features, training ages and weekly exercise volumes were similar in sprinters and endurance athletes. There were no significant differences in terms of diastolic parameters and among the groups. In sprinters, isovolumetric relaxation time (IVRT) and isovolumetric contraction time (IVCT) were significantly shorter than in controls. In endurance athletes, IVCT was significantly shorter than in controls. Both sprinters and endurance athletes had longer ET compared with controls. TEI Index was significantly lower in sprinters and endurance athletes than in controls.
Our results suggest that both aerobic and anaerobic training seem to have a positive effect on myocardial performance. This comparable effect might be a result of frequently exercising, especially aerobic exercising in sprinters' training programs.
据报道，有氧训练对心肌性能指数有积极影响。本研究的目的是检测短跑运动员和耐力运动员的心肌性能指数（MPI）。
共有66名精英男性运动员（36名短跑运动员和30名耐力运动员）以及33名年龄匹配的久坐不动的对照者自愿参与本研究。对所有组进行了超声心动图评估，并测量了TEI指数作为心肌性能指数的标志物。
短跑运动员和耐力运动员的人口统计学特征、训练年限和每周运动量相似。各舒张参数在各组之间无显著差异。在短跑运动员中，等容舒张时间（IVRT）和等容收缩时间（IVCT）显著短于对照组。在耐力运动员中，IVCT显著短于对照组。与对照组相比，短跑运动员和耐力运动员的射血时间（ET）均更长。短跑运动员和耐力运动员的TEI指数显著低于对照组。
我们的结果表明，有氧训练和无氧训练似乎都对心肌性能有积极影响。这种相似的影响可能是经常锻炼的结果，尤其是短跑运动员训练计划中的有氧运动。
