New episode on the optimal exercise intensity, duration, and frequency to prevent and reverse heart aging!

In this podcast episode, Dr. Benjamin Levine discusses his groundbreaking research, which reveals how three weeks of bed rest can have a more detrimental impact on fitness than 30 years of aging.

Dr. Levine details his research findings that show how a structured exercise regimen can reverse up to 20 years of heart aging by improving both shrinkage and compliance, as well as enhancing aspects of vascular age by 15 years.

He also discusses how resistance training and aerobic training have profound differences on the heart, what risks are linked to high-intensity exercise, why recovery is key for the heart, how exercise duration and intensity affect coronary calcium levels, what exercise dose increases Afib risk, and so much more.

This episode is a must!

A great conference is over in Bergen. Met many inspiring scientists doing critical work to understand sex and gender differences. Also fortunate to spend quality time with incredible Florence Haseltine, national academy of medicine winner and a true legend!

Did not expect our project to get so much media attention, but I guess it reflects the massive interest in sauna and cold exposure in Norway and Scandinavia! Also never been this easy to find and recruit participants so I am def. not complaining 😄

@proferikrichter Absolutely! Moving from the US to Norway, it has also been my impression that there is a greater push in Europe, perhaps related to stricter open science policies? 🤷🏼‍♀️

[Ann-Katrin (Anka) Grotle, PhD @AnkaGrotle]

Well said!! It also seem this is becoming a trend when applying for research funding...
