Yoga y respuesta quimiorrefleja a la hipoxia y la hipercapnia
Lancet (London, England)
|November 18, 2000
Resumen
La práctica de yoga y la respiración lenta reducen significativamente la sensibilidad al quimiorreflejo. Los practicantes de yoga a largo plazo muestran una disminución generalizada en el quimiorreflejo, lo que indica adaptaciones fisiológicas más amplias más allá de la respiración lenta.
Área de la Ciencia:
- Fisiología Fisiología Fisiología.
- Biología Integrativa Biología Integrativa.
- Estudios de yoga Estudios de yoga Estudios de yoga Estudios de yoga
Sus antecedentes:
- La sensibilidad al quimiorreflejo es crucial para la regulación cardiovascular.
- Se sabe que el yoga influye en las funciones autónomas, incluidos los patrones de respiración.
- El impacto específico del yoga en la sensibilidad quimiorrefleja sigue sin estar claro.
Objetivo del estudio:
- Para investigar el efecto de la práctica del yoga en la sensibilidad al quimiorreflejo.
- Para diferenciar los efectos de la respiración lenta de la práctica general de yoga en la sensibilidad al quimiorreflejo.
Principales métodos:
- Los participantes se sometieron a evaluaciones de la sensibilidad quimiorrefleja.
- Las tasas de respiración fueron manipuladas para simular la respiración lenta inducida por el yoga.
- La sensibilidad al quimiorreflejo se comparó entre los practicantes de yoga a largo plazo y los controles.
Principales resultados:
- Una tasa de respiración lenta, característica del yoga, redujo sustancialmente la sensibilidad al quimiorreflejo.
- La práctica de yoga a largo plazo resultó en una reducción generalizada de la sensibilidad quimiorrefleja.
- Estos hallazgos sugieren que el yoga induce adaptaciones más allá de los cambios respiratorios agudos.
Conclusiones:
- La respiración lenta es un factor clave para reducir la sensibilidad quimiorrefleja.
- La práctica sostenida de yoga conduce a alteraciones más profundas y generalizadas en el control de quimiorreflejo.
- El yoga puede ofrecer un enfoque no farmacológico para modular la regulación cardiovascular autónoma.

01:24Redox Reactions
Oxidation-reduction or redox reactions involve the transfer of electrons from one molecule or atom to another. When an atom gains an electron, another atom must lose an electron, meaning oxidation and reduction must occur together. Since the redox occurs in pairs, the atom that gets oxidized is also called the reducing agent or reductant, and the atom that is reduced is also called the oxidizing agent or oxidant. A straightforward way to remember the definitions of oxidation and reduction is...
01:23Introduction to Chemical Reactions
All chemical reactions begin with a reactant, the general term for one or more substances entering the reaction. Sodium and chloride ions, for example, are the reactants in the production of table salt. One or more substances produced by a chemical reaction are called the product. Chemical reactions follow the law of conservation of mass, which means that matter cannot be created nor destroyed in a chemical reaction. The components of the reactants—the number of atoms and the elements—are all...
01:08Types of Chemical Reactions: Exchange and Reversible
An exchange reaction is a chemical reaction in which both synthesis and decomposition occur, chemical bonds are both formed and broken, and chemical energy is absorbed, stored, and released.
A special kind of exchange reaction is the oxidation-reduction reaction, or the redox reaction. These reactions involve the transfer of electrons from one compound to another. The electrons in these reactions commonly come from hydrogen atoms, which consist of an electron and a proton. A molecule gives up a...

01:23Redox Equilibria: Overview
A reduction-oxidation reaction is commonly called a redox reaction. In a redox reaction, electrons are transferred from one species to another rather than being shared between or among atoms. The reducing agent or reductant is the species that loses electrons and gets oxidized in the process. The species that gains electrons and gets reduced in the process is the oxidizing agent or oxidant. Redox reactions are represented as two separate equations called half-reactions, where one equation...
01:22Heterogeneous Catalysis
Heterogeneous catalysis involves a catalyst in a different phase from the reactants. It is a process where the catalyst and the reactants are in distinct phases, typically solid and gas or liquid.Most heterogeneous catalysts are metals, metal oxides, or acids. The list includes transition metals like iron (Fe), cobalt (Co), nickel (Ni), palladium (Pd), platinum (Pt), chromium (Cr), manganese (Mn), tungsten (W), silver (Ag), and copper (Cu). These metals possess partially vacant d orbitals that...
01:27Redox Reactions
Redox reactions are vital biochemical processes that underpin energy metabolism in cells. These reactions involve the transfer of electrons between molecules, occurring in tandem as oxidation and reduction. Oxidation refers to the loss of electrons, while reduction denotes their gain. This coupling ensures the seamless flow of electrons through metabolic pathways. For example, in bacterial metabolism, glucose undergoes oxidation to carbon dioxide, while oxygen is simultaneously reduced to...
