What else can I help you with?
What is the concentric joint action of the hamstring curl?
flexion exstention
What is a contraction in which the muscle shorten and work is done?
This is muscle flexion or isotonic contraction.
What is the prime mover of a bicep curl?
the bicep contracts in a concentric contraction which means the muscles has shortened. remember muscles can only pull they can not push. also the bicep curl can be described as elbow flexion and when the weight is lowered is called elbow extention. hope it helps
An example of flexion is the?
Simply stated, flexion is when the angle around a joint is decreased from it's normal position (from the anatomical position) in the SAGITTAL plane. The sagittal plane is an imaginary line that splits your body into left and right pieces. All flexion moves in this plane. Ex. Flexion of the bicep requires you to pull your forearm (decrease the angle) toward your head. That motion running along the side of your body is also in the sagittal plane
What is the proper form for a bicep curl concentric movement?
The proper form for a bicep curl concentric movement involves slowly lifting the weight up towards your shoulders while keeping your elbows close to your body and not swinging the weight.
A sporting example of a concentric movement?
Hahahahahahahahahah A Divinaaaaaaaa
What is an example of a concentric exercise and how does it benefit the muscles?
An example of a concentric exercise is a bicep curl, where you lift a weight towards your shoulder. This exercise benefits the muscles by primarily targeting the bicep muscle, helping to strengthen and tone it.
What is the difference between muscle flexing and and muscle extension?
when u flex it, it tightens, when u extend it, it stretches Flexion is when a muscle action decreases the angle at a joint, extension is when the angle increases. A simple example is bicep curl, flexion is when the hand is brought up towards the shoulder, decreasing the angle at the elbow joint. Just because a muscle is performing flexion or extension does not not mean it is contracting or stretching, that is eccentric and concentric movement. A muscle can still be tight when performing extension.
Is concentric isotonic contraction is defined as tension developing in the muscle as it shorten?
That is correct, the muscle shortens as it contracts. E.g. A bicep curl, the bicep muscle as you lift the wight up is Isotonic contraction. :)
What joint do you use during a bicep curl up phase?
During the up phase of a bicep curl, the primary joint used is the elbow joint. As you lift the weight, the biceps brachii muscle contracts and causes flexion at the elbow, allowing the forearm to move closer to the upper arm. This action primarily targets the biceps while also engaging the forearm muscles.
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!
Is a bicep curl an isotonic or isometric exercise?
A bicep curl is an isotonic exercise.
