Inspiratory flow resistive loading improves respiratory muscle function and endurance capacity in recreational runners
Abstract
The purpose of this study was to assess the efficacy of inspiratory flow resistive loading (IFRL) on respiratory muscle function, exercise performance and cardiopulmonary and metabolic responses to exercise. Twenty‐four recreational road runners (12 male) were randomly assigned from each gender into an IFRL group (n=8) and sham‐IFRL group (n=8), which performed IFRL for 6 weeks, or a control group (n=8). Strength (+43.9%Δ), endurance (+26.6%Δ), maximum power output (+41.9%Δ) and work capacity (+38.5%Δ) of the inspiratory muscles were significantly increased (P<0.05) at rest following the study period in IFRL group only. In addition, ventilation (−25.7%Δ), oxygen consumption (−13.3%Δ), breathing frequency (−11.9%Δ), tidal volume (−16.0%Δ), heart rate (HR) (−13.1%Δ), blood lactate concentration (−38.9%Δ) and the perceptual response (−33.5%Δ) to constant workload exercise were significantly attenuated (P<0.05), concomitant with a significant improvement (P<0.05) in endurance exercise capacity (+16.4%Δ) during a treadmill run set at 80% in IFRL group only. These data suggest that IFRL can alter breathing mechanics, attenuate the oxygen cost, ventilation, HR, blood lactate and the perceptual response during constant workload exercise and improve endurance exercise performance in recreational runners.

In the citing paper
“However, in studies using CLTs at intensities below the threshold and including a sham-training group, improvements in the RMT groups exceeded those of the sham-training groups [66,71,79,85,88] with only one exception.[83]”

In the citing paper
“Of the fifteen studies testing with a CLT below the 85% threshold, only three specified changes in respiratory sensations, two [79,88] of them reported a significant decrease while one [83] did not.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
