Within the research, researchers wished to see what performed an even bigger position in arterial stiffness (an indicator of coronary heart well being) for ladies: cardiorespiratory (coronary heart and lung) health or physique composition.
The research analyzed 146 ladies between the ages of 16 and 58. Members’ cardiorespiratory health was measured utilizing an train check and researchers additionally collected their physique fats proportion, fat-free mass index (a measure of fat-free tissue—like bone, muscle, and fluid), and imply arterial stress (i.e., blood stress within the arteries).
Subsequent, these findings have been analyzed alongside the individuals’ arterial stiffness to see what associations (if any) stood out.
The 2 largest elements related to arterial stiffness have been fat-free mass index and imply arterial stress. Particularly, a better fat-free mass and a decrease imply arterial stress have been each linked to decrease arterial stiffness.
This held agency within the research no matter physique fats proportion, however older age was linked to arterial stiffness. Which means the quantity of fat-free mass (like muscle) you carry could play an even bigger position in coronary heart well being than physique fats or complete physique weight, however age performs an element as properly (one thing to remember, as ladies are inclined to lose muscle mass as they age).
Constructing muscle via focused way of life modifications—e.g., weight coaching and consuming extra protein—is a dependable method to improve your fat-free mass.
Nevertheless, it’s essential to keep in mind that this research was observational, so we will’t know for positive that enhancing muscle mass will all the time lead to higher coronary heart well being.
