Even when you account for age, fitness, and cholesterol, how smoothly an athlete’s heart rate recovers after a hard race can tell you whether they have early heart artery plaque.

Alterations in the autonomic and haemodynamic response to prolonged high‐intensity endurance exercise in individuals with coronary artery calcification

Cross-Sectional Study

2025 Mar

Scientists found that athletes with hardened arteries had lower heart rate variability during a tough bike race — and this low variability was still a good sign of artery problems even after accounting for age, smoking, and other risk factors. So yes, it supports the idea that this heart measure can signal artery issues.

Similar Assertions

When athletes with early heart artery plaque stop a hard race, their heart rate doesn’t adjust as smoothly as those without plaque, suggesting their body’s automatic control system for heart rate and blood pressure isn’t working as well.

For older male athletes, doing a lot of hard but not extreme exercise—like fast running or cycling—seems to be linked to less calcium buildup in heart arteries over time, compared to doing super intense workouts.

Just doing short, intense workouts isn’t linked to more heart plaque—what matters more is how many total hours you spend training over time.

For older male athletes who work out really hard—like sprinting or intense cycling—doing more of this super intense exercise over time seems to be linked to more calcium building up in their heart arteries, which could be a sign of plaque growth.
