Universal machine -- One of several types of weight lifting devices where weights are on a track or rails and are lifted by levers or pulleys. Deveeloped in the early 60s by Chuck Coker, the phrase originally referred to a multi-station gym.
Unsaturated fatty acids (UFA) -- UFAs are important in lowering blood cholesterol and may thus help prevent heart disease. They are essential for normal glandular activity, healthy skin, mucous membranes and many metabolic processes.
Unsaturated fatty acids (UFA) are fatty acids whose carbon chain contains one or more double or triple bonds, and which are capable or receiving more hydrogen atoms. They include the group polyunsaturates, are generally liquid at room temperature and are derived from vegetables, nuts, seeds or other sources. Examples of unsaturated fatty acids include corn oil, safflower oil, sunflower oil and olive oil. Replacing saturated fats with unsaturated fats in the diet can help reduce cholesterol levels.
A small amount of highly unsaturated fatty acid is essential to animal nutrition. The body cannot desaturate a fat, such as vegetable shortening or margarine, sufficiently by its own metabolic processes to supply this essential need. Therefore, the dietary inclusion of unsaturated or polyunsaturated fats is vital.
The three essential fatty acids (those which the body is unable to manufacture) are linoleic acid, linolenic acid, and arachidonic acid. However, these fatty acids can be synthesized from linoleic acid if sufficient intake occurs. Linoleic acid should provide about 2% of total dietary calories. Corn, safflower and soybean oils are high in linoleic acid.
Cf. monounsaturated fat, polyunsaturated fat, saturated fat.
Upper abs -- Abdominal muscles above navel (see lower abs).
