Exercise-induced hypoxemia (EIH) is well-described in endurance-trained athletes during
both maximal and submaximal exercise intensities. Despite the drop in oxygen (O2) …

Background The production of reactive oxygen (ROS) and nitrogen species (RNS) is a
fundamental feature of mammalian physiology, cellular respiration and cell signalling, and …

Context: Beetroot juice is a naturally rich source of inorganic nitrate (NO 3−), a compound
hypothesized to enhance endurance performance by improving exercise efficiency …

Physical exercise has many benefits, but it might also have a negative impact on the body,
depending on the training level, length of workout, gender, age and fitness. The negative …

The respiratory muscle fatigue seems to be able to limit exercise performance and may
influence the determination of maximal oxygen uptake (V̇O 2max) or maximum aerobic …

Purpose: It has been reported that~ 50% of endurance-trained men demonstrate exercise
induced arterial oxyhemoglobin hypoxemia (EIAH) during heavy exercise. However, this …

Background Support for long-distance research and clinical collaborations is in high
demand and has increased owing to COVID-19–related restrictions on travel and social …

Background and Objectives: Angiogenesis describes the outgrowth of new capillaries from
already existing ones. Different biomarkers regulate this process. Physical exercise and …

Exercise causes alterations in redox homeostasis (ARH). Measuring ARH in elite athletes
may aid in the identification of training tolerance, fatigued states, and underperformance. To …

This study examined to what extent athletes exhibiting exercise-induced hypoxemia (EIH)
possess an altered redox status at rest, in response to exercise at sea level (SL) and during …
