Exercise physiology loss of integrity to the blood brain barrier. Hyperthermia also can lower cerebral blood flow, and raise brain temperature. Researchers once attributed fatigue to a build-up of lactic acid in muscles. However, this is no longer believed. Rather, lactate may stop muscle fatigue by keeping muscles fully responding to nerve signals. The available oxygen and energy supply, and disturbances of muscle ion homeostasis are the main factor determining exercise performance, at least during brief very intense exercise. Each muscle contraction involves an action potential that activates voltage sensors, and so releases Ca ions from the muscle fibre’s sarcoplasmic reticulum. The
Oxygen cocktail suffering from hypoxia, cardiovascular system and digestive tract diseases, having problems with the immune system, insomnia, chronic fatigue syndrome and excessive body weight. The contraindications of the oxygen cocktail are: Oxygen cocktail The oxygen cocktail is a foamy substance containing a beverage drink (juice, milk, etc.) enriched in gaseous oxygen. The drink is used as part of oxygen therapy by a number of Russian medical institutions; their research suggest that the drink, by supplying oxygen, reduces chronic fatigue syndrome and hypoxia and activates metabolism. The oxygen cocktail was developed in the 1960s by the Russian academician N. N. Sirotinin. While
