Exhaustive exercise Judo lipid peroxidation.doc

Exhaustive exercise Judo lipid peroxidation [Abstract] an exhaustive exercise can lead to an increase of endogenous free radicals, increased lipid peroxidation, constitutes a cell membrane system damage, membrane fluidity, integrity, and permeability decreased, affecting the movement of cells normal physiological function, as important reasons for occurrence of fatigue. [Keywords:] Judo lipid peroxidation exhaustive exercise Judo athletes in the competition use of “bear to vote” and other technical actions fall opponents, mainly by increasing the explosive force of muscle contraction, the increase of the power of technology can enhance the ability to control. An explosive judo athletes must pass the basic forces and speed, technology, combining the sensitivity of coordination in order to play the best results. Therefore, one should not only be technically exhaustive exercise efforts, but also particularly in the growth, such as power, efforts to improve the speed of muscle contraction. Exhaustive movement of free radicals and lipid peroxidation in question is to study the functional aspects of judo athlete a good entry point. First, the basic theory The so-called free radicals are those with odd number of electrons in the chemicals that they are free with an unpaired electron, the electron led to the high reactivity of these substances. Including oxygen free radicals (O - 2), hydroxyl radical (OH -), hydrogen peroxide (H 2O 2), singlet oxygen (O 2). and exercise the most significant increase of oxygen free radicals. Lipid peroxidation refers to the radical and unsaturated fatty acids on the cell membrane (RH) oxidation reaction to produce toxic effects on cells of peroxide (ROOH). Radicals can not only directly attack the cell membrane damaging effects on cells, At the same time the spontaneous decomposition of lipid peroxides can form more free radicals, free radicals attack other double bond caused a chain reaction. malondialdehy
