Power is the product of
force and velocity
During free weight exercise, resistive torque varies with:
The horizontal distance from the weight to the body
T/F: Knee wraps can improve lifting performance
TRUE
The pivot point of a lever is called a
fulcrum
The degree to which a force tends to rotate an object about a specified fulcrum is called:
torque
The maximal force that a muscle can generate at a specified velocity is called:
strength
work =
force x distance
T/F: Most force is generated around the resting length
TRUE
The muscle that exhibits unipennate pennation
tibialis posterior
The muscle that exhibits bipennate pennation
rectus femoris
The muscle that exhibits multipennate pennation
deltoid
The muscle that exhibits fusiform pennation
biceps brachii
The muscular growth that occurs from resistance training is called?
hypertrophy
Hypertrophy of a muscle is primarily the result of which of the following: increased cross section of the muscle, increased muscle cell numbers, increased muscle cell hydration, thickening of the connective tissue?
Increased cross section of the muscle
Type Iia fibers are:
