What is the correct phase order of the stretch shortening cycle?
The correct phase order of the stretch-shortening cycle is eccentric contraction, amortization phase, and concentric contraction. This sequence allows for energy storage during the eccentric phase, a brief pause to transition from lengthening to shortening, and then rapid muscle shortening in the concentric phase for powerful movement.
What muscle actions would be classified as isotonic contractions?
Isotonic contractions involve muscle actions where the muscle length changes as it contracts against a constant load. There are two types: concentric contractions (shortening of the muscle during contraction) and eccentric contractions (lengthening of the muscle during contraction).
What effect do calcium slow channels have on shortening or lengthening the contraction of the heart muscle?
Calcium slow channels, also known as L-type calcium channels, play a crucial role in regulating the duration of cardiac muscle contraction. Activation of these channels leads to an influx of calcium ions into the cardiac muscle cells, which triggers contraction. Inhibition of these channels can result in decreased contractility and lengthening of the contraction phase of the heart muscle.

What is Lengthening of muscle is called?
The lengthening of a muscle is called 'relaxing'. As the SHORT muscles work antagonistically- when one contracts, one relaxes. Therefore as one muscle shortens the other lengthens. This is between the bicep and tricep and the hamstring and quadricep. When a muscle shortens it also thickens, this is why you can feel your muscle rise when you bring your arm towards you.
What includes both concentric and eccentric contractions?
Isotonic muscle contractions involve both concentric (muscle shortening) and eccentric (muscle lengthening) phases. In isotonic contractions, the muscle changes in length while maintaining a constant tension, such as when lifting a weight or performing a bicep curl.
What word a noun is used to describe muscle shortening with stimulation?
The noun for muscle shortening is called contraction.
What are muscles not allowed to do?
Muscles do not "push". That is, their power comes from shortening (pulling) rather than lengthening (pushing). The human body -- as with most animal bodies -- is organized with groups of muscles that oppose each other, enabling us to push and pull and twist (and shout) -- but each muscle's primary force comes from shortening.
What are two ways pitch can be changed?
1) Doppler shift 2) shortening or lengthening the wavelength produced by the source.
What is the medical term meaning shortening or tightening of a muscle?
Contraction is the medical term meaning the normal shortening or tightening of a muscle.
Does isotonic muscle contractions involve shortening of muscle?
Yes
What is chiropractic abbreviation ART?
ART is the acronym for Active Release Therapy, which is a form of soft-tissue therapy that is sometimes employed by doctors of chiropractic, physiotherapists, massage therapists, and other manual therapists. ART involves shortening a specific muscle through appropriate movement, applying pressure and then lengthening the muscle.
