The Claim
Bimagrumab administration over six months in healthy older adults does not impair maximal oxygen uptake (VO2max) or cardiopulmonary exercise capacity, despite inducing significant increases in lean mass and reductions in fat mass.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In healthy older adults, taking bimagrumab for six months does not reduce aerobic fitness or heart and lung function during exercise, even though it increases muscle mass and decreases fat mass.
See the scientific wording
Bimagrumab does not impair maximal oxygen uptake (VO2max) or cardiopulmonary exercise capacity in healthy older adults over six months, despite significant increases in lean mass and reductions in fat mass.
A drug blocks a signal that normally stops muscle growth and promotes fat storage, causing muscles to get bigger and fat to shrink. The heart does not grow larger or work harder because the muscle gain is not large enough to demand more blood flow, so the body's ability to use oxygen during exercise stays the same.
What the research says
1 studyBimagrumab helped older adults gain muscle and lose fat, but didn't hurt their heart — which means their ability to exercise probably stayed the same, even if it didn't get better.
