When can a muscle generate the most force?
The force -length relationship indicates that muscles generate the greatest force when at their resting (ideal) length, and the least amount of force when shortened or stretched relative to the resting length.
What happens to the amount of total force the muscle generates during?
What happens to the amount of total force that the muscle generates during the stimulated twitch? Total force is altered by the starting resting length. If the muscle is lengthened the passive force increases, and if the muscle is shortened the active force increases.
What would increase the force generated by a muscle?
As with skeletal muscle, changes in length alter the active force by varying the degree of overlap of the thick myosin and thin actin filaments. An increase in the level of circulating epinephrine and norepinephrine from the sympathetic nervous system also increases the force of contraction.
Does the force generated by the muscle change with each additional?
Yes, it is greater than the previous stimulations. Does the force generated by the muscle change with each additional stimulus? You correctly answered: b. As the stimulus frequency increased, the muscle tension generated by each successive stimulus also increased, and a limiting maximum value was observed.
What is the force length relationship?
The force-length relationship describes the dependence of the steady-state isometric force of a muscle (or fiber, or sarcomere) as a function of muscle (fiber, sarcomere) length. The force-length relationship is considered one of the basic properties of muscle.
Is a bicep curl isotonic?
Aerobic exercises like walking, running, hiking, swimming, skiing, and dancing are all considered isotonic exercise. So are resistance training exercises that involve movement, such as squats, pushups, pull ups, bench presses, deadlifts, and bicep curls.
What is length tension relationship?
The length-tension (L-T) relationship of muscle basically describes the amount of tension that is produced by a muscle as a feature of it’s length. That is to say, when tested under isometric conditions, the maximal force produced or measured will be different as the muscle lengthens or shortens.
When the stimulus frequency reaches a value beyond which no further?
When the stimulus frequency reaches a value beyond which no further increases in force are generated by the muscle, the muscle has reached its You correctly answered: maximal tetanic tension.
