NASM Chapter 5
Terms in this set (54)
the science concerned with the internal and external forces acting on the human body and the effects produced by these forces.
bending movement in which relative angles between 2 adjacent segments decreases.
straightening movement in which the relative angle between 2 adjacent segments increase.
Examples of sagittal plane movements
1. Bicep Curl
2. Tricep Pushdowns
4. Front Lunges
5. Calf Raises
7. Climbing Stairs
the extension of a joint beyond the normal limit or range of motion, often resulting in injury.
bisects the body into front/back halves.
Movements go side-to-side.
movement toward the midline of the body (similar to flexion)
movement away from the midline of the body (similar to extension)
Examples of frontal plane movements
1. side lateral raises
2. side lunges
3. side shuffling
rotation of a joint toward the middle of the body.
rotation of a joint away from the middle of the body
anterior position to a lateral position
lateral position to an anterior position
Examples of Transverse Plane Movements
1. Cable Trunk Rotations
2. Dumbbell Chest Fly
3. Throwing a ball/frisbee
5. Swinging a bat
motion of the shoulder blades
shoulder blades come close together -> <-
shoulder blades mover farther away from each other <- ->
shoulder blades move up
shoulder blades move down
constant muscle tension developed,
force is produced,
movement occurs through range of motion.
(phase of isotonic movement)
deceleration (lowering a weight),
acceleration (lifting a weight)
constant muscle length,
no visible movement with or against resistance
constant moving action, the speed of movement is fixed.
the interaction between 2 entities or bodies that results in either acceleration or deceleration of an object.
Characterized by magnitude (how much) and direction.
the resting length of a muscle and the tension the muscle can product at this resting length.
the relationship of muscle's ability to produce tension at differing shortening velocities.
The faster you lift, the harder it gets)
muscle groups working together to produce movement around a joint.
Joint motion caused by pulling on bones.
Bones are levers,
Muscles create the motion, and resistance can be body weight or object weight.
is the joint axis
3 kinds of levers
1st class: fulcrum in the middle, like a seesaw.
Ex. nodding the head
2nd Class: resistance in the middle. like a load in a wheelbarrow.
Ex. full body push ups or calf raises
3rd Class: effort in the middle (MOST LIMBS IN THE HUMAN BODY ARE 3RD CLASS)
Ex. human forearm during bicep curl.
(fulcrum=elbow, effort=bicep, load=dumbbell)
Movement around an axis
force that produces rotation, measured in newton-meters.
(the closer a weight is to the point of rotation (the joint), the less torque it creates, and the easier movement becomes)
the HMS response to internal and external environmental stimuli.
how the CNS integrates internal and external sensory information with previous experiences.
utilization of motor control through practice and experience, leading to skilled movement.
Ex. riding a bike
the change in motor behavior over time.
groups of muscles recruited by CNS to provide movement.
the CNS gathers and interprets sensory information and to select and execute proper motor responses.
Two types of Feedback
1. internal feedback
2. external feedback
sensory information is used by the body to reactively monitor movement and the environment.
information provided by an external source, such as a trainer or mirror.
2 forms of external feedback
1. knowledge of results-how a client did after a move
2. knowledge of performance-feedback during a movement
