Name four factors that influence contractile force and two that influence velocity and duration of contraction?
The four factors that influence contractile force are the number of muscle fibers stimulated, the relative size of the fibers, the frequency of stimulation and the degree of muscle stretch. Factors that influence the velocity and duration of contraction are the muscle fiber type, load and recruitment.
What factors directly influence venous blood flow?
Skeletal Muscle contraction, breathing movements, and vasoconstriction.
What is a concentric contraction?
concentric contraction is atype of muscle contraction which the muscle shortens while genrating aforce The muscle shortens to produce movement. A muscle contraction in which shortening occurs.
What is a contraction in which the muscle shorten and work is done?
This is muscle flexion or isotonic contraction.
True or false When the contraction of a skeletal muscle is studied in the laboratory by applying an electrical charge to the muscle the contraction is called a muscle twitch.?
true
Which muscle contraction does acetylcholine and norepinephrine affect?
Acetylcholine and norepinephrine both affect smooth muscle contraction. They stimulate contraction in some muscles and inhibits contraction in others.
What factors affect muscle tone?
By constant low-level asychronous stimulation producing minute contraction of random motor units.
What affect joint stability?
3 factors 1) type of bone 2) position and strength of ligaments 3) contraction of muscle
What factors influence velocity and duration of muscle contraction?
Load placed on the muscle
How would a drug that interferes with cross bridge formation affect muscle contraction?
a drug that interferes would prevent muscle contraction
List the biomechanical factors that affect human strength?
Neural controlMuscle cross-sectional areaArrangement of muscle fibersMuscle lengthJoint angleMuscle contraction velocity
Factors that inhibit muscle contraction?
Muscle fatigue is the main factor that inhibits muscle contraction. Muscles need oxygen and energy to contract and muscle fatigue is the lack of oxygen in a muscle. The build up of lactic acid is a factor of muscle fatigue.
What is muscle contraction without muscle shortening is what kind of contraction?
Isometric contraction
Constant contraction of a muscle is?
constant contraction of a muscle is called the muscle tone

Factors that influence the velocity and duration of contraction are the muscle fiber type, load and recruitment.
What are the major factors that promote the flow of venous blood?
Factors are, skeletal muscle contraction, breathing movements and vasoconstriction of veins.[venoconstriction].
What factors directly influence venous blood flow?
Skeletal Muscle contraction, breathing movements, and vasoconstriction.
