Biomechanics of Human Skeletal Muscle - Part 2: Strength, Length, Velocity

These flashcards cover key concepts related to the biomechanics of human skeletal muscle as discussed in the lecture.

Muscular Strength

The ability of a given muscle group to generate torque at a particular joint.

Torque

The rotational force that causes an object to rotate around an axis.

Force-Length Relationship

The principle that determines the force a muscle can produce based on its length at a given moment.

Active Insufficiency

The inability of a muscle to generate force when it is slack.

Passive Insufficiency

The restriction of joint range of motion when muscles are fully stretched.

Moment Arm

The perpendicular distance from the line of action of a force to the axis of rotation.

Concentric Contraction

A type of muscle contraction where the muscle shortens while generating force.

Eccentric Contraction

A type of muscle contraction where the muscle lengthens while generating force.

Stretch-Shortening Cycle

A muscle action that involves an eccentric contraction followed by a concentric contraction.

Muscular Power

The product of muscular force and the velocity of muscle shortening.
