MHID-31585802025Sport Sciences for Health

Nikola Todorovic, Jovan Kuzmanovic, Dejan Javorac, Sergej M Ostojic

Purpose Exercise induces transient physiological disruptions, including immune suppression and gastrointestinal (GI) disturbance. Molecular hydrogen (H₂), an endogenously produced gas with antioxidant and anti-inflammatory properties, may play a protective role in this context. While the therapeutic potential of exogenous H₂ has been widely explored, little is known about endogenous hydrogen respo

Over the last two decades, a plethora of disease models and human studies have confirmed the beneficial effects of molecular hydrogen (H2), a simple biotherapeutic gas. Recent small-scale studies evaluating the effects of hydrogen-rich water (HRW) on various metabolic conditions pointed to advantageous effects of HRW in regulating blood lipid profiles. However, to the best of the authors’ knowledge,

The intricate relationship between the gut microbiota, its metabolites, and human health has garnered significant attention in recent years because of its potential role in the development of many diseases [1]. Among the various metabolites produced by the microbiota, a group of organic acids, known as short-chain fatty acids (SCFAs), has emerged as key regulators of host energy metabolism. These

The molecular footprints of COVID-19 occur everywhere, even reaching the family of biologically active gases and gasotransmitters. Besides nitric oxide and hydrogen sulfide, COVID-19 might also alter the homeostasis of dihydrogen (H2), another gaseous bioactive molecule produced endogenously by the human gut bacteria. Many studies have shown various alterations of the gut microbiota in patients wit
