What factors affect muscle contraction?
the degree of muscle stretch is affect the strength or force of skeletal muscle contraction
When a patient lifts his leg while the doctor presses down on it is diagnostic for?
They are testing muscle strength. Scores range from no contraction of the muscle (as seen in paralysis of that muscle) to being able to contract the muscle and withstand resistance (which is an expected finding).
How is the all-or-none response related to the strength of a muscle contraction?
The all-or-none response means that a muscle fiber contracts fully or not at all in response to a stimulus. The strength of a muscle contraction is determined by the number of muscle fibers that are recruited to contract, rather than the degree of contraction of individual muscle fibers. Therefore, the all-or-none response influences the overall strength of a muscle contraction by determining how many muscle fibers are activated.
Cardiac muscle strength?
Cardiac muscle has the ability to rapidly adapt the strength of contraction based on how much stretch there is in the muscle.
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.
What is the relationship between the load on a muscle and its strength of contraction?
Strength of contraction increases as the load increases until the load becomes excessive.
What is the Relationship between a load on a muscle its strength of contraction?
Strength of contraction increases as the load increases until the load becomes excessive.
What is the difference between a strong muscle contraction and a weak muscle contraction?
one would be the amount of contractile strength that results from a muscle contraction.
What relationship do neural drive and the strength of muscle contraction have?
A good one
The contractility of heart muscle is its?
contraction strength at any given fiber length
What is muscle treppe?
•Increased contraction in response to multiple stimuli of same strength
How does resistance training work?
Resistance training works by inducing muscle contraction. Doing this helps build muscles and strength. That is because muscle contraction generates tension on the muscle and forces it to move.
