isometric contraction
It means just what it sounds like - someone is not moving at all, not even one muscle.
The Agonist muscle. In contrast, the muscle group that has passive action(the muscle being stretched) is called the antagonis muscle. For example, when doing a bicep curl. Your biceps are the agonists and your triceps would be the antagonists.
Involuntary muscles are those which function without the need for conscious thought or effort. The heart beats without having to be thought about for it to beat. As a contrasting example, the act of typing this answer is a form of voluntary muscle movement, actively thinking about moving fingers to specific keys on a keyboard.
The muscle that attaches to a non-moving bone is called the origin muscle. This muscle provides stability and support to the bone it is attached to, allowing other muscles to create movement around it. An example is the trapezius muscle, which originates from the base of the skull and attaches to the spine and shoulder blades.
It is called the origin.
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
When a muscle ceases to perform without losing nerve function, this condition is called muscle atrophy. Muscle atrophy occurs when there is a decrease in muscle mass, often due to disuse, inactivity, or various medical conditions. Despite the nerve being intact, the muscle fibers can weaken and shrink, leading to reduced strength and functionality.
The all-or-none law applies to individual muscle fibers within a skeletal muscle. This means that when a muscle fiber is stimulated by a motor neuron, it will either contract maximally or not at all, depending on whether the stimulus reaches the threshold for activation.
No
the muscle would be the flexor muscle because it contracts
by moving it
