At the same time, fatigue has been suggested as one of the factors giving rise to delayed-onset muscle soreness (DOMS). The aim of this study was to investigate the efficacy of a specific electrical stimulation (ES) treatment (without elicited muscular contraction) on two ... -
Oxygen Variations
26 septembre 2023, BALESTRA, Costantino; Virgili, Fabio; Mrakic-Sposta, Simona, HE Bruxelles Brabant
Livre/Ouvrage ou monographieFor many years, diving and hyperbaric medicine has strived to increase our understanding of the effects of environmental stressors on human pathophysiology. It has demonstrated the importance of oxygen and has taught us not to fear this oxidative molecule, the name of which is derived from the ancient Greek meaning the “acid generator” or Oxy-Gene; indeed, at that time, it was believed that all acids ... -
Hyperbaric medicine
Livre/Ouvrage ou monographieOxygen (both its presence and absence) acts as a potent signaling mechanism in many, if not most, cellular processes. Oxygen has been used therapeutically mainly to alleviate or correct hypoxia, and has been administered in supra-atmospheric doses in the form of hyperbaric oxygen (a method derived from diving medicine practices, but has been used in non-diving applications since the 1960s). Hyperbaric ... -
