Yoga and chemoreflex response to hypoxia and hypercapnia
Lancet (London, England)
|November 18, 2000
Summary
Yoga practice and slow breathing significantly reduce chemoreflex sensitivity. Long-term yoga practitioners show a generalized decrease in chemoreflex, indicating broader physiological adaptations beyond just slow breathing.
Area of Science:
- Physiology
- Integrative Biology
- Yoga Studies
Background:
- Chemoreflex sensitivity is crucial for cardiovascular regulation.
- Yoga is known to influence autonomic functions, including breathing patterns.
- The specific impact of yoga on chemoreflex sensitivity remains unclear.
Purpose of the Study:
- To investigate the effect of yoga practice on chemoreflex sensitivity.
- To differentiate the effects of slow breathing rate from general yoga practice on chemoreflex sensitivity.
Main Methods:
- Participants underwent assessments of chemoreflex sensitivity.
- Breathing rates were manipulated to simulate yoga-induced slow breathing.
- Chemoreflex sensitivity was compared between long-term yoga practitioners and controls.
Main Results:
- A slow breathing rate, characteristic of yoga, substantially reduced chemoreflex sensitivity.
- Long-term yoga practice resulted in a generalized reduction of chemoreflex sensitivity.
- These findings suggest yoga induces adaptations beyond acute breathing changes.
Conclusions:
- Slow breathing is a key factor in reducing chemoreflex sensitivity.
- Sustained yoga practice leads to more profound, generalized alterations in chemoreflex control.
- Yoga may offer a non-pharmacological approach to modulate autonomic cardiovascular regulation.

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...
