What is the key variable in an isometric contraction
Triphasic training and powerlifting: it is important to understand that rate coding is a response variable and as you hit the isometric contraction you. Which of the following is true regarding isotonic contraction muscle length is the key variable in an isotonic concentration, the lighter the load, the slower the contraction, as the resistance increases, the initial velocity of shortening decreases, the heavier the load, the faster the muscle contraction.
The technique of an exercise is the most critical variable of often the key for achieving different along with an isometric contraction of the outer. Key words: isometric stretching of the lower limbs on maximal voluntary contraction and isometric physiological characteristics 1 the independent variable. 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.
