50 Kinesiology Terms
Anatomy & Physiology Terms
1. Anterior
Refers to the front side of the body or body part. For example, the chest is anterior to the spine.
2. Posterior
Describes the back side of the body. The shoulder blades are located on the posterior side of the torso.
3. Proximal
Closer to the point of origin or attachment on the body. The shoulder is proximal to the hand.
4. Distal
Further from the point of origin. The fingers are distal to the elbow.
5. Flexion
A movement that decreases the angle between two body parts. Bending your elbow is an example of flexion.
6. Extension
Movement that increases the angle between body parts, such as straightening a bent knee.
7. Abduction
Movement of a limb away from the body’s midline, such as raising the arms sideways.
8. Adduction
Movement toward the body’s midline, like lowering your arms to your sides.
9. Origin
The fixed attachment point of a muscle, usually closer to the center of the body.
10. Insertion
The movable end of the muscle, where the action occurs when the muscle contracts.
Muscle & Movement Terms
11. Agonist
The primary muscle responsible for a specific movement, often called the “prime mover.”
12. Antagonist
The muscle that opposes the action of the agonist, helping to control or slow the movement.
13. Synergist
A muscle that assists the agonist in performing a movement and helps stabilize the joint.
14. Isometric
A type of muscle contraction where the muscle generates force without changing length, like holding a plank.
15. Isotonic
A contraction where the muscle changes length while producing force, such as lifting or lowering a dumbbell.
16. Concentric
The muscle shortens as it contracts, like curling a weight upward during a bicep curl.
17. Eccentric
The muscle lengthens under tension, such as lowering a weight slowly back to the starting position.
18. Neuromuscular Junction
The site where a motor neuron communicates with a muscle fiber to initiate contraction.
19. Motor Unit
A single motor neuron and all the muscle fibers it stimulates; it controls muscle force production.
20. Muscle Fiber Types
Muscles are composed of slow-twitch (Type I) fibers for endurance and fast-twitch (Type II) fibers for power and speed.
Biomechanics & Movement Science
21. Kinetics
The study of forces and torques that cause motion, including gravity and muscle-generated forces.
22. Kinematics
Describes the motion of bodies without considering the forces involved, focusing on speed, velocity and joint angles.
23. Gait Analysis
The systematic study of human walking or running to assess and improve movement efficiency or identify abnormalities.
24. Center of Gravity
The point in the body where mass is evenly distributed and balance is maintained.
25. Ground Reaction Force
The force exerted by the ground on the body when standing, walking or jumping; a key concept in injury prevention.
26. Levers
Bones act as levers in the body, allowing muscles to produce movement by applying force at joints.
27. Torque
Rotational force applied around a joint or axis; critical for understanding movement mechanics.
28. Planes of Motion
Body movement occurs in three planes: sagittal (forward/back), frontal (side-to-side) and transverse (rotational).
29. Range of Motion (ROM)
The degree to which a joint can move through its normal limits, important in flexibility and injury recovery.
30. Balance and Stability
Balance is the ability to maintain control of body position; stability is the resistance to disturbance or loss of balance.
Exercise Science & Physiology
31. VO₂ Max
The maximum rate of oxygen the body can use during intense exercise; a key indicator of cardiovascular fitness.
32. Lactate Threshold
The exercise intensity at which lactic acid begins to accumulate in the blood, causing fatigue.
33. ATP (Adenosine Triphosphate)

34. Aerobic Metabolism
Energy production in the presence of oxygen; efficient for long-duration, low-to-moderate intensity activities.
35. Anaerobic Metabolism
Energy production without oxygen; used for short, high-intensity bursts of activity but results in fatigue more quickly.

Why a Good Education Matters
It’s critical to have a comprehensive education and learning experience in kinesiology because the field is both scientifically complex and practically applied.
Kinesiology terms aren’t just vocabulary—they represent precise biological, physiological and biomechanical processes. Misusing or misunderstanding these terms can lead to incorrect assessments, ineffective interventions or even injuries in real-world settings.
Here’s why in-depth education matters:
● Accuracy in Communication: Whether you’re working with clients, patients or other healthcare professionals, using kinesiology terminology correctly ensures clear, consistent communication.
● Informed Decision-Making: Knowing the difference between terms like eccentric contraction and isometric hold impacts how you design a program or evaluate movement.
● Clinical and Ethical Responsibility: Professionals in rehabilitation, physical therapy or sports training have a duty to use evidence-based language rooted in scientific understanding.
● Confidence and Professionalism: Mastery of kinesiology language allows you to present yourself as a credible expert, whether you’re explaining a treatment plan or educating a client.
● Success in Advanced Study or Licensure: Graduate programs and certification exams often demand fluent use of technical terminology, so foundational knowledge is key to advancement.
