PMID 28174465WHAT IT FOUND
The increase in respiratory muscle strength after 8 weeks of aerobic training was not linked to the blood pressure reduction, although training lowered systolic and diastolic pressure and improved walking distance.
Key findings
01Aerobic training lowered systolic and diastolic blood pressure in the exercised group.
02Aerobic training increased respiratory muscle strength, measured as inspiratory and expiratory pressures.
03Respiratory pressure and walking distance results were not correlated with systolic or diastolic blood pressure levels after training.

What it does not show
The paper does not report how participants were assigned to the intervention and control groups. The control group had 20 participants, so comparisons with the 70-participant exercise group are limited. All participants had hypertension controlled by medication, and the authors suggest medication may have influenced the lack of correlation between conditioning measures and blood pressure. Participants did not make any special diet and lacked nutritionist follow-up, which may explain no weight or BMI change. Only 8 weeks of training were assessed, so durability beyond that period is not shown.

The easy way to misread this
Do not conclude that increased respiratory muscle strength causes or predicts the blood pressure reduction. The study found no correlation between respiratory pressure results and blood pressure levels after training.
