Kinesiology 147 Final Study Guide Flashcards
(27 cards)
Concentric muscle action
Shortening of the muscle.
Eccentric muscle action
Lengthening of the muscle.
Isometric muscle action
No changes in muscle length.
Atrophy
Wasting of the muscle.
Hypertrophy
- Building of the muscle
- Increase in the size of muscle.
Hyperplasia
Increase in the number of muscle cells.
What is a Prime mover?
The primary muscle that is used during a lift.
What is a Stabilizer Muscle?
Muscle acts to stabilize one joint so the movement can be performed in another.
Overload Principle
- Body adapts to what you’re doing.
- Increase strength by gradually increasing weight/workload.
SAID Principal
(Special Adaptation to Imposed Demands)
- Certain exercises produce adaptations specific to the activity and only in the muscles stressed by the action.
DOMS
Delayed Onset Muscle Soreness.
- Soreness in the muscles hours/days after unpracticed/hard exercise.
- Felt most strongly 24-72 hours after exercise due to tearing in the muscle fibers.
Acute Muscle Soreness
- Pain in muscles during/immediately after physical activity.
- Pain appears with muscle contractions, disappears after 2-3 minutes of relaxation.
Relative strength
The body’s ability to produce power relative to the individual’s body weight.
Intensity
Amount of resistance/weight lifted.
Absolute Strength
Maximum amount of force that can be produced in 1 lift for 1 rep.
Rep Max (RM)
Maximum amount of weight that can be used, with good technique, for a specific number of reps.

Movement and Techniques
Barbell Bench Press
- Eccentric down and Concentric up.
- Pause when bar touches chest; no bouncing off of chest.
Movement and Techniques
Barbell Back Squat
- Eccentric down and Concentric up.
- Pause once thigh is parallel with the ground
- Be sure to have an anterior pelvic tilt during lift.
Movement and Techniques
Lat pull down
- Concentric down and Eccentric up
- Pull bar in front of the face down to the top of the sternum.
Spotting Techniques - Barbell Bench Press
Hands under the bar, ready to assist if needed; not aiding in lifting the weight.
