Background In the last 5 years since our last systematic review, a significant number of
articles have been published on the technical aspects of muscle near-infrared spectroscopy …

Simple Summary Respiratory muscle training (RMT) improves physical performance through
increased efficiency of the muscles implicated in respiration, an aspect that preserves the …

This study aimed to evaluate if the changes in oxygen saturation levels at intercostal
muscles (SmO2-m. intercostales) assessed by near-infrared spectroscopy (NIRS) using a …

Background Inspiratory muscle fatigue has been shown to have effects on limbs blood flow
and physical performance. This study aimed to evaluate the influence of an inspiratory …

This study aimed to examine sex differences in oxygen saturation in respiratory (SmO2-m.
intercostales) and locomotor muscles (SmO2-m. vastus lateralis) while performing physical …

Exercise increases the cost of breathing (COB) due to increased lung ventilation (V˙ E),
inducing respiratory muscles deoxygenation (∇ SmO2), while the increase in workload …

Background The fatigue of the inspiratory musculature, particularly the diaphragm, has been
demonstrated to exert systemic effects on the body, impacting cardiovascular and …

This study investigates the differences in metabolic energy cost and physiological
adaptations between carrying a suspended backpack and a traditional backpack during …

Purpose: This study evaluated the effects of exercise training (ET) and inspiratory muscle-
loaded exercise training (IMLET) on ventilatory response and intercostal muscle …

TO THE EDITOR: We commend Kipp et al.(1) for their important study on the metabolic cost
of breathing across agegroups and sexes, providing insights into the increased respiratory …
