Technical note — Enlarged heart / Athlete’s paradox
Enlarged heart is a common heart ailment, an adaptation that the kind heart goes through in response
to hypertension or high blood pressure. This enlarged heart is often seen in sedentary individuals, with
little or no exercise and high body weight and is identified as a serious risk to the heart. Now athletic
training or even recreational exercise can bring about the exact same adaptation — enlarged heart. The
difference is that, in people who work out, the heart enlarges because it gets bigger in size, strength
and vascularity, and in sedentary folk it enlarges to make up for the lack of the exact same things. The
enlarged heart in people who work out regularly is also called as the ‘athlete’s heart’ and is
characterized by low or normal BP levels and low body fat levels.
