What else can I help you with?
What happens to the h zone during contraction?
width of H zone decreases
What happens to the Z line during muscle contraction?
During muscle contraction, the Z line moves closer together, causing the muscle to shorten and generate force.
What happens to the strength of contraction during wave summation?
It increases about to about four times greater than a normal contraction for skeletal muscle.
What is measured by the amount of time a muscle group can sustain a contraction?
Muscle strength measures the amount of force a muscle can exert during contraction. The determining factor of strength is the fast twitching fibers.
What happens If a muscle is applied to a load that exceeds the muscle's maximum tension?
The muscle length will not change during a contraction.
What happens to density during thermal contraction?
It increases. The volume of a material decreases in contraction, while the mass remains the same.
What happens to a Z line during contraction?
the Z line discs come closer together and the & the width of the I band decreases.. or narrows
What type of contraction happens in javelin?
In javelin throw, the primary type of muscle contraction that occurs is the concentric contraction. This happens when the muscles shorten while generating force, especially during the explosive phases of the throw, such as the arm extension and body rotation. Eccentric contractions may also occur as the muscles lengthen under tension during the follow-through. Overall, the combination of these contractions contributes to the power and accuracy of the throw.
What happens during combustion of hydrogen?
combustion which result to a colourless smoky flame (depending on the amount of carbon present) giving off carbon dioxide and water
What happens to the origin and insertion of a muscle during contraction?
During muscle contraction, the origin (the attachment point of the muscle that remains relatively fixed) and the insertion (the attachment point of the muscle that moves) move closer together. This results in the muscle shortening and causing movement at the joint.
What happens to the amount of energy during a chemical reaction?
Do it yourself idiot.
What muscle contraction occurs in the biceps brachii during the upward phase of the bicep curl?
a concentric contraction- a concentric contraction involves the muscle length, shortening during a contraction! YA-trick-YA!
