The Claim
In older obese adults with heart failure with preserved ejection fraction, a 20-week intervention of caloric restriction combined with aerobic exercise significantly improves peak oxygen consumption (VO2peak) by approximately 5–7%, while the addition of resistance training to this regimen does not further enhance VO2peak improvement.
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 and doing aerobic exercise for 20 weeks increases peak oxygen consumption by 5–7%. Adding strength training to this routine does not increase oxygen consumption further.
See the scientific wording
In older obese adults with heart failure with preserved ejection fraction, caloric restriction combined with aerobic exercise significantly improves peak oxygen consumption (VO2peak) by approximately 5–7% over 20 weeks, but adding resistance training does not further enhance this improvement.
Losing excess body fat and doing regular cardio reduces stiffness in the arteries and lowers the workload on the heart, allowing the heart to pump more blood with each beat. This delivers more oxygen to the muscles during physical activity, which lets the person breathe more efficiently and sustain higher levels of exertion.
What the research says
1 studyIn older, obese adults with heart problems, doing diet and cardio improved their heart and lung fitness by 5–7%, and adding weight training didn’t make that improvement any better—even though it made their legs stronger.
