Cornstarch (or corn flour) usually works best with water-based sauces, reduced stock, jus from meats, wine sauces, wine-soy-vinegar Chinese sauces, etc. Make a thin paste of cornstarch and water, and stir that into the very warm liquids in the pot or pan. Over-heating or over-cooking will break down the starches.
maintaining, or pertaining to, the same length; of equal dimensions. isometric contraction. muscle contraction without appreciable shortening or change in distance between its origin and insertion. isometric exercise. active exercise performed against stable resistance, without change in the length of the muscle.
There are two types of isotonic contractions: (1) concentric and (2) eccentric. In a concentric contraction, the muscle tension rises to meet the resistance, then remains the same as the muscle shortens. In eccentric, the muscle lengthens due to the resistance being greater than the force the muscle is producing.n an isotonic contraction, tension remains unchanged and the muscle's length changes. Isotonic contractions differ from isokinetic contractions in that in isokinetic contractions the muscle speed remains constant.
