      <trans-abstract xml:lang="en">
        <p>This article analyses informative morphometric and haemodynamic parameters of cardiac function in highly skilled handball players competing in the Russian Super League. Attention is drawn to selected anthropometric data of the athletes in relation to morphometric and specific haemodynamic components of left ventricular function. Additionally, at rest, indicators are examined that reflect the heart's ability to effectively withstand loads of various types.</p>
