• Arthrokinematics - The motions of joints in the body.
  • Balance Threshold - How far one can go outside their base of support without losing control of his or her center of gravity.
  • Biomechanics - The study of mechanical laws relating to the movement or structure of living organisms. The mechanics of biological, especially muscular activity (as in locomotion or activity).
  • Bracing - Occurs when you have contracted both the abdominal, lower back, and buttock muscles at the same time.
  • Cardiorespiratory System - A system of the body composed of the cardiovascular and respiratory systems.
  • Cardiovascular System - A system of the body composed of the heart, blood, and blood vessels.
  • Core - The core muscles attach directly to the vertebrae and involves the lumbo pelvic hip complex (LPHC). The LPHC involves the anatomical structures of the lumbar, thoracic and cervical spine, the pelvic girdle and the hip joint.
  • Drawing- in Maneuver - A  maneuver used to recruit the local core stabilizers by drawing the navel in towards the spine
  • Fascia - The outermost layer of connective tissue that surrounds the muscle.
  • Force - The interaction between two entities or bodies that result in either the acceleration or deceleration of an object.
  • Force Velocity Curve - The ability of muscles to produce force with increasing velocity.
  • Force Couples - The synergistic action of muscles to produce movement around a joint.
  • Functional Strength - The ability of the neuromusculoskeletal system to efficiently and effectively produce force, reduce force, and dynamically stabilize the entire human movement system to during human movement. 
  • GPS - Global Positioning System, an accurate worldwide navigational and surveying facility based on the reception of signals from an array of orbiting satellites.
  • Hip Hinge - The concept of the hip hinge can be described as the spine remaining stiff and neutral while movement occurs about the hip joint.
  • Kinetic Chain - The combination and interrelation of the nervous, muscular, and skeletal systems.
  • Length-Tension Relationship - Refers to the length at which a muscle can produce the greatest force.
  • Lumbo-Pelvic-Hip Complex - This is the lumbar, thoracic, and cervical spines along with the pelvic girdle, and the hip joint.
  • Neuromuscular - of or relating to nerves and muscles.
  • Neuromuscular Efficiency - The ability of the human movement system to allow agonists, antagonists, synergists, and stabilizers to work synergistically to produce force, reduce force and dynamically stabilize the entire human movement system. This process helps to maintain optimal length-tension relationships, force couple relationships, and arthrokinematics (nasm).
  • Neutral Spine - A posture where there is not exaggeration of any of the normal curvatures of the spine.
  • Neutralizers - Muscles that counteract the unwanted action of other muscles.
  • Planes of Motion - Frontal plane, sagittal plane and transverse plane.
  • Frontal plane - An imaginary bisector that divides the body into front and back halves
  • Sagittal plane - An imaginary bisector that divides the body into left and right halves
  • Transverse plane - An imaginary bisector that divides the body into top and bottom halves
  • Plyometric Training - Defined as quick, powerful movement involving an eccentric contraction, followed immediately by an explosive concentric contraction.
  • Power Endurance -  Is an athletes ability to sustain high power output for an extended period of time.
  • Rate of force Production - Ability of muscles to exert maximal force output in a minimal amount of time or the rate of force development is the time from stimulus, to reach the required force.
  • Respiratory System - A system of organs (the lungs & respiratory passageways) that collects oxygen from the external environment and transports it to the blood stream.
  • Reactive Strength - Reactive strength is a ready response of strength to a stimulus be it physical, visual or auditory.
  • SAID Principle - Specific adaptation to imposed demand.
  • Skill Performance - The dexterity or coordination in the execution of learned physical tasks. The learning of a new skill follows a predictable course whereby unnecessary motor units are eliminated and the skill progressively becomes relegated to almost a subconscious level, executed almost in a reactive state. Skills are learned through a process called deliberate practice, practice that is not always inherently fun. - NASM
  • Stretch-Shortening Cycle - An active stretch (eccentric contraction) of a muscle followed by an immediate shortening (concentric contraction) of that same muscle. This occurs when a muscle transitions from deceleration to a rapid acceleration.
  • Synergistic Dominance - When synergists compensate for a weak or inhibited prime mover in an attempt to maintain force production and functional movement patterns.
  • Trigger Points - A sensitive area of the body, stimulation or irritation of which causes a specific effect in another part, esp. a tender area in a muscle that causes generalized musculoskeletal pain when overstimulated.
