In this article we will look at how your heart rate affects your metabolic health, regardless of other factors.
In the study we will look at, cardiorespiratory fitness was inversely associated with insulin resistance and other key cardiometabolic risks, including liver fat, in people with or without type 2 diabetes.
Let's go and see more.
CARDIORESPIRATORY AND CARDIOVASCULAR HEALTH
As we explained in "Do I need to exercise to have heart health?"the greater the so-called aerobic capacity, or the maximum amount of oxygen the body can use during exercise, the better our cardiovascular and cardiorespiratory health.
CARDIORESPIRATORY AND CARDIOMETABOLIC HEALTH
This study was one of the first to show significant associations between key cardiometabolic risk factors such as liver fat content with cardiorespiratory fitness in people with or without type 2 diabetes.
One of the striking things is that even relatively small variations in cardiorespiratory fitness were associated with increased liver fat content and insulin resistance, which were significantly higher in people with relatively low cardiorespiratory health than those with relatively high cardiorespiratory health.
Similarly, subjects with lower cardiorespiratory fitness had unusually high levels of insulin resistance, liver fat, blood pressure and inflammatory markers.
So we see again, how important it is the preservation of muscle mass, but also the combination with aerobic exercise, as with our cardiopulmonary health, our metabolic health in general improves.
