When you train consistently—whether it’s endurance training, speed work, or strength—your heart adapts. That adaptation, which is often referred to as “athlete’s heart,” is not a disease. It’s your cardiovascular system getting more efficient at pumping blood, delivering oxygen, and sustaining workload. But most of what we’ve defined as a “normal” athlete’s heart comes from studies of men. And we’re now beginning to see that women’s hearts don’t adapt the same way. I’ve been saying this for years: women are not small men.
A systematic review in Clinical Cardiology highlights what many female athletes have experienced firsthand: female hearts have distinctly different structural, electrical, and risk patterns compared with male hearts. Understanding those differences isn’t just academic; it matters for interpretation, performance, and health.
