Increased work of breathing (Wb) triggers the inspiratory muscle metaboreflex, which elevates systemic blood pressure in response to diaphragmatic fatigue. To counteract this, dietary nitrate could act as a source of nitric oxide, which is known to improve muscle power and efficiency (Jones et al., 2018). This study examines the hypothesis that acute nitrate supplementation would attenuate this response. Utilizing the KH2 device from PowerBreathe, 20 healthy participants (mean age: 21.1 ± 2.5 years; range: 18–30 years) underwent a resistive breathing task (RBT) for a total of three minutes at 60% of their maximal inspiratory pressure (MIP). All 20 participants …

Hypoxia is a condition in which the body’s tissues are deprived of oxygen and has deleterious effects on cognition, perception, and performance. Hypoxia has a myriad of symptoms such as euphoria, difficulty concentrating, headache, fatigue, nausea, dizziness, tunnel vision, and more. Outward signs of hypoxia include cyanosis (blueing of the fingertips and lips), tremors, loss of coordination, pallor, and complexion change, and can be used to notice the onset of hypoxia in others. Many factors are known to contribute to the manifestation of hypoxia, namely altitude, exposure duration, and certain physiological conditions such as heart problems and low blood flow …
