| Sports Science and Medicine: hypertrophy |
An increase in the size of a tissue or organ due to growth of individual cells without an increase in the number of cells. Chronic hypertrophy of a muscle refers to a relatively permanent increase in its size, in contrast to temporary increases (transient hypertrophy) due, for example, to muscle pumping. Chronic hypertrophy results from resistance training that is repeated over a long period whereas muscle pumping occurs during a single exercise bout. See also hyperplasia.
| Columbia Encyclopedia: hypertrophy |
hypertrophy (hīpûr'trəfē), enlargement of a tissue or organ of the body resulting from an increase in the size of its cells. Such growth accompanies an increase in the functioning of the tissue. In normal physiology the growth in size of muscles (e.g., in an athlete as a result of increased exercise) and also the enlargement of a uterus in pregnancy are caused by hypertrophy of muscle cells. In pathology the thickening of the heart muscle from overstrain, as in hypertension (high blood pressure), is the result of hypertrophy. An organ subjected to extra work (e.g., the one kidney left to function after surgical removal of the other) usually compensates by enlarging; in such cases hyperplasia, an increase in the number of cells, generally accompanies hypertrophy.
| Veterinary Dictionary: hypertrophy |
Increase in volume of a tissue or organ produced entirely by enlargement of existing cells.
