The Claim

In community-dwelling older adults aged 65–80, 10 weeks of inspiratory muscle training at 60–80% of baseline maximum inspiratory pressure increases maximum inspiratory pressure by 20–25% (d=0.788–1.032).

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.

Cause and effect
1 study reviewed
In plain English

In adults aged 65 to 80 who live at home, 10 weeks of breathing exercises at 60–80% of their maximum breathing capacity increases their maximum breathing strength by 20–25%.

See the scientific wording

In community-dwelling older adults aged 65–80, 10 weeks of inspiratory muscle training at 60–80% of baseline maximum inspiratory pressure significantly increases maximum inspiratory pressure by 20–25% (d=0.788–1.032), confirming that high-intensity IMT effectively strengthens the primary breathing muscles.

Why this might work

When the breathing muscles are forced to work harder during inhalation, they grow thicker and stronger, allowing them to pull more air into the lungs with each breath.

    The IMT group showed large, statistically significant improvements in MIP and MIP% (P<0.005, d>0.78), directly resulting from the prescribed training intensity (60–80% MIP). This confirms the intervention’s physiological effect on inspiratory muscle strength.
