The Claim

In community-dwelling older adults aged 65–80, 10 weeks of moderate- to high-intensity peripheral muscle training combined with aerobic exercise increases maximum expiratory pressure by 0.876 standard deviations and MEP% by 0.932 standard deviations.

In plain English

In adults aged 65 to 80, 10 weeks of combined strength and aerobic exercise increases expiratory muscle strength by 0.876 standard deviations for maximum expiratory pressure and by 0.932 standard deviations for MEP%.

See the scientific wording

In community-dwelling older adults aged 65–80, 10 weeks of moderate- to high-intensity peripheral muscle training combined with aerobic exercise significantly increases maximum expiratory pressure (MEP) by 0.876 standard deviations (p=0.003) and MEP% by 0.932 standard deviations (p=0.002), suggesting that resistance training targeting limb and core musculature may enhance expiratory muscle strength through indirect biomechanical mechanisms.

Why this might work

When a person does strength training with their arms and legs, their core muscles must tighten to keep the body stable. Over time, this repeated tightening makes the muscles used for forceful breathing out — like the abdominal wall and diaphragm — stronger and more efficient. These muscles then generate more pressure when exhaling, improving the ability to cough and clear the airways.

  1. Study: Comparative effectiveness of progressive moderate- to high-intensity peripheral and inspiratory muscle training combined with aerobic exercise in community-dwelling older adults: A randomized clinical trial

    This study found that older adults who did strength training with their arms and legs, plus walking exercise, got better at forcefully breathing out — just like the claim said. Their breathing muscles got stronger without directly training their lungs.
