What is the muscle action that occurs when the muscle lengthens while exerting a force to overcome a resistance?

The muscle doesn't lengthen to exert a force. There is actually a muscle on the other side of the bone, that is contracting, exerting the force. Example, most everyone knows of the Bicep (the big muscle on the your arm that guys like to flex for the ladies). Well, the tricep is on the other side (on the back of your arm, connecting to the elbow) and that muscle contracts in order to extend your arm outwards.


What does cellular activity do during the phases of Eccentric contraction?

During the eccentric contraction phase, cellular activity involves lengthening the muscle fibers while generating force. This phase creates tension in the muscle as it elongates, allowing for controlled movement and resistance against external forces. Additionally, cellular processes such as protein breakdown and remodeling contribute to muscle adaptation and strength gains.


What is a contraction in which the muscle shorten and work is done?

This is muscle flexion or isotonic contraction.


Is a cricket bowl a concentric contraction?

No, a cricket bowl is not a concentric contraction. A concentric contraction occurs when a muscle shortens while generating force, such as when lifting a weight. In cricket, a bowl refers to the action of the bowler delivering the ball to the batsman. This motion involves a combination of eccentric and concentric muscle contractions.


Does muscle contraction always promote movement?

No, muscle contraction doesn't always promote movement. For example, in an isometric contraction, the muscle does not change length, so movement is not produced. Additionally, some muscles can contract to stabilize joints without producing visible movement.

An eccentric contraction is one that causes a muscle to lengthen.


Give examples for concentric and eccentric muscle contractions in gait cycle?

while kicking a football, the Quadriceps muscle contracts concentrically to straighten the knee and the Hamstrings contract eccentrically to decelerate the motion of the lower limb.In concentric muscle contraction muscle length decreases along with contraction of the fibres while in eccentric muscle contraction the muscle length increases.Dr Santosh


What are the types of contractions doing a situp?

A sit up is an eccentric muscle contraction.


Can skeletal muscle contract without shortening?

Yes. One possibility is that the load on the muscle exceeds the tension produced by the muscle so that the muscle actually lengthens during contraction (eccentric contraction).


What are some ways muscle contractions can graded?

Muscle contraction can be: Concentric, Eccentric, Static.

Which type of strength training uses machines to increase muscle strength and endurance?

Types of Strength Training Exercises Static (isometric) exercise = muscle contraction without a change in the length of the muscle Dynamic (isotonic) exercise = muscle contraction with a change in the length of the muscle Concentric contraction = muscle applies force as it shortens Eccentric contraction = muscle applies force as it lengthens Types of Dynamic Exercise Constant resistance = constant load throughout a joint's range of motion Variable resistance = changing load to provide maximal resistance throughout a joint's range of motion Eccentric loading = placing load on a muscle as it lengthens Plyometrics = sudden eccentric loading and stretching followed by a concentric contraction Speed loading = moving a load as rapidly as possible Isokinetic exercise = exerting force at a constant speed against an equal force
