The Claim
Twelve weeks of walking at WHO-recommended volumes improves cardiorespiratory fitness in middle-aged and older adults with depression, with no significant difference between moderate and vigorous intensities.
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 middle-aged and older adults with depression, 12 weeks of walking at recommended public health volumes increases cardiorespiratory fitness, and this improvement is the same whether the walking is done at a moderate or vigorous pace.
See the scientific wording
Twelve weeks of walking at WHO-recommended volumes improves cardiorespiratory fitness in middle-aged and older adults with depression, with no significant difference between moderate and vigorous intensities, suggesting that even moderate activity can enhance aerobic capacity in this population.
Walking regularly makes the muscles better at using oxygen by growing more energy factories and blood vessels inside them, which lets the heart and lungs work more efficiently over time.
What the research says
1 studyFor older adults with depression, walking 150 minutes a week at a slow pace or 75 minutes a week at a fast pace both made their hearts and lungs stronger — and neither was better than the other.
