A near isotonic contraction is known as Auxotonic contraction. 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.
Isostasy (Greek ísos 'equal', stásis 'standstill') or isostatic equilibrium is the state of gravitational equilibrium between Earth's crust (or lithosphere) and mantle such that the crust "floats" at an elevation that depends on its thickness and density.
The concentric portion is usually the part of the exercise that you think of as “the lift”—it’s the pressing portion of a bench press, standing up out of a squat, pulling the bar from the ...
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
The great utility of the isoinertial method and at the same time what makes it different from the normal isotonic muscle movement lies in the fact that the action isotonic developed in conventional exercises (strength machines and free weights), the resistance is constant throughout the whole of movement in both the concentric phase in which ...
While this definition always applies there are various sub-definitions which exist in order to emphasise how effort is being applied during specific isometric exercises. In a yielding isometric exercise the ambition is to maintain a particular body position; this may also be called maintaining an isometric hold.
Video loop of isallobars showing the motion of a cold front. An isobar (from Ancient Greek βάρος (baros) ' weight ') is a line of equal or constant pressure on a graph, plot, or map; an isopleth or contour line of pressure. More accurately, isobars are lines drawn on a map joining places of equal average atmospheric pressure reduced to sea ...
This creates a cloudy water column which travels under the tidal influence as the wave orbital motion is in equilibrium. The Null-point hypothesis has been quantitatively proven in Akaroa Harbour, New Zealand, The Wash , U.K., Bohai Bay and West Huang Sera, Mainland China, and in numerous other studies; Ippen and Eagleson (1955), Eagleson and ...
