What factors affect muscle contraction?
the degree of muscle stretch is affect the strength or force of skeletal muscle contraction
What is the mechanical force of muscle contraction is generated by?
The mechanical force of muscle contraction is generated by a sliding of thin filaments past thick ones.
A contraction in which a muscle exerts force lengthens and is overcome by a resistance?
Eccentric contraction (isotonic)
What is the most common form of force muscle production?
The most common form of muscle force production is the concentric contraction force.
What is muscle force and its vector representation?
Muscle force is the force produced by the contraction of a muscle. Force vectors, torque vectors, and difference vectors can all be used to help describe this force.
What is a mucle contraction?
A muscle contraction happens when too much force or stress is forced upon a muscle cavity. Dr. Whitmore PHD
What type of contraction in which the muscle fibers do not shorten are called?
If the muscle can not shorten because the muscle is trying to move a load that is greater than the force, then the contraction is isometric.
How does the frequency of stimulation affect the amount of force generated by the muscle?
Increasing the stimulus to an isolated muscle increases the strength of a contraction. A muscle begins to contract when the stimulus is given; however, if the muscle does not finish contracting before the next stimulus hits, then the force of the contraction will increase to finish the contraction. This is known as wave summation.
What is the definition of Muscular Strength?
Muscular Strength is defined as "The maximum force that can be generated by a muscle or group of muscles in one singular contraction. Muscular strength is affected by the following factors. -Cross sectional area of the muscle -Angle of pull -Length -Age -Gender -Number of fibres (motor units) recruited -Speed of contraction, depends on (Slow or fast twitch muscle fibres) -Shape of muscle -Type of contraction
In a concentration contraction the muscles shorten to produce movement?
True.
What is it called when a muscle applies force without moving?
isometric contraction
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.
