Most of the studies of athlete's heart have been performed on Caucasian and yet, evidence suggests that there are racial differences in the response of the heart to certain pathological conditions such as hypertension. This study aimed to evaluate the morphologic cardiac changes in a group of highly trained Cameroonian handball players.
We studied cardiac morphology and function as assessed by echocardiography at rest in 21 asymptomatic international level handball players and 21 age-, sex-, height- and weight-matched sedentary controls. Echocardiographic variables were compared between groups using unpaired t-test. Compared with controls, wall thickness, relative wall thickness (h/R), left ventricular (LV) mass, LV end diastolic diameter (LVEDD) and left atrial diameter were significantly greater in athletes. None of the athlete exhibited a wall thickness above 12 mm. The ejection fraction (EF) and the mitral pattern on pulsed wave Doppler did not differ in the two groups.
Both LVEDD and wall thickness of elite Cameroonian handball players are increased. There is an increased h/R. The LV EF was normal and not supranormal, as is sometimes believed. These cardiac changes are consistent with cardiac adaptation required in this type of sportsmen who are submitted both in endurance and resistance training.
大多数关于运动员心脏的研究都是在白种人身上进行的，然而，有证据表明心脏对某些病理状况（如高血压）的反应存在种族差异。本研究旨在评估一组训练有素的喀麦隆手球运动员的心脏形态学变化。
我们对21名无症状的国际水平手球运动员和21名年龄、性别、身高和体重匹配的久坐不动的对照组人员进行了静息状态下的超声心动图检查，以评估心脏形态和功能。使用非配对t检验比较两组之间的超声心动图变量。与对照组相比，运动员的壁厚、相对壁厚（h/R）、左心室（LV）质量、左心室舒张末期直径（LVEDD）和左心房直径明显更大。没有一名运动员的壁厚超过12毫米。两组的射血分数（EF）和脉冲波多普勒上的二尖瓣模式没有差异。
喀麦隆精英手球运动员的LVEDD和壁厚均增加。h/R增加。左心室EF正常，并非如有时所认为的超常。这些心脏变化与这类接受耐力和阻力训练的运动员所需的心脏适应性一致。
