Cardiac remodelling in strength and endurance athletes

It looks that TB is right on the money!

"Due to an increased dynamic load, the heart of the endurance athlete responds predominantly with eccentric hypertrophy. Endurance-trained hearts are subject to increased volume and pressure loading, leading to specific myocardial changes such as left ventricular dilatation and increased left ventricular mass.

Strength training is associated with a marked elevation in systolic and diastolic blood pressure. The heart of the strength-trained athlete responds to sudden and large pressure overload with concentric left ventricular hypertrophy, in some cases accompanied by increases in left ventricular diameters.

Both strength training and endurance training cause left ventricular hypertrophy, but left ventricular wall thickness is found to be higher in strength training, while dilatation of the left ventricle is a prominent feature of endurance trained hearts. "

Good: thicker walls and bigger chamber. Bad: thicker walls, smaller chamber.

Nice find....so do both and the heart gets hit from every angle.
