The Claim
In older obese adults with heart failure with preserved ejection fraction, caloric restriction combined with aerobic exercise reduces left ventricular mass and arterial stiffness, and the addition of resistance training does not further reduce these measures.
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 older adults who are obese and have heart failure with preserved ejection fraction, losing calories through diet and doing aerobic exercise lowers heart muscle mass and stiffening of arteries; adding weight training does not lower them further.
See the scientific wording
In older obese adults with heart failure with preserved ejection fraction, caloric restriction combined with aerobic exercise reduces left ventricular mass and arterial stiffness, and adding resistance training does not further reduce these measures.
Losing excess body fat and doing regular cardio lowers inflammation and makes arteries more flexible, which reduces the pressure the heart must work against. This lets the thickened heart muscle shrink back to a normal size and improves blood flow.
What the research says
1 studyIn older obese adults with a type of heart failure, cutting calories and doing cardio helped shrink the heart muscle and loosen stiff arteries—but adding weight training didn’t make those improvements any better. It just made their legs stronger.
