Older-adult strength training is not a lung test
In short
A trial of 69 adults aged 60–85 found no lung-function interaction after 12 weeks. Breathing-pressure and chair-rise changes differed by group, but significant pre–post changes occurred only in controls. Track each outcome separately.
Completing 12 weeks of resistance training did not establish better lung function in this trial. The Journal of Aging Research study recruited 69 adults aged 60–85 who had not joined structured exercise for at least a year. Thirty-one entered supervised resistance training three times weekly; 38 formed the control group. The useful lesson for a training log is to distinguish attending sessions from demonstrating a specific health outcome.
Which outcomes changed differently?
| Measure | Group-by-time result | Interpretation |
|---|---|---|
| Spirometry | No significant interaction | Lung-function improvement not established |
| Inspiratory and expiratory pressure | Significant interaction | Significant pre–post changes only in controls |
| One-minute chair rise | Significant interaction | Significant improvement only in controls |
Maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) assess pressure generated by the breathing muscles. They are different from spirometry. A group-by-time interaction means the groups changed differently; it does not itself say the training group improved. Grip strength and oxygen saturation also showed no significant interaction. Selected blood and exhaled-breath biomarkers differed in their changes, but the collected abstract does not give the direction and magnitude needed to call those differences reduced inflammation or stronger immunity.
How should the findings change a training log?
- Record exercise selection, load, repetitions, and weekly attendance.
- Keep breathing tests and chair-rise results in separate dated entries with the test name.
- Repeat assessments under comparable conditions and compare each result with its own baseline.
For fairlift, this means a completed lifting session remains evidence of the work performed, not a substitute for a breathing assessment. A note that stairs felt easier can be useful personal context, but it is not a spirometry result. The Muscle Index calculator compares strength from the three main lifts; it cannot certify lung function or immune status. This separation also prevents selective reporting: a favorable number should not silently stand in for every other outcome. The logging approach is our practical interpretation, rather than an intervention tested by this paper.
The participants were older adults returning from a long period without structured exercise. A 12-week study in this population neither establishes effects in regular lifters nor shows that resistance training has no value overall.
Frequently asked questions
Did resistance training improve lung function?
The spirometry outcomes showed no significant group-by-time interaction. This trial did not establish improved lung function from the intervention.
Does a breathing-pressure interaction mean the training group improved?
No. Different changes between groups are not the same as an improvement within the training group; significant pre–post MIP and MEP changes appeared only in controls.
Can Muscle Index assess breathing health?
Muscle Index addresses relative strength in the three main lifts. Breathing function and immune status require their own appropriate assessments.
