- 7Quantity of matterMass
(kg)
Example: Hydroworx (level of water knee or chest height) - 8Amount of gravitational force (ma) on the a bodyWeight
Example: Bench Press (weight coming towards and being pushed away from the body) - 9AKA center of mass; point around which body's weight is equally balanced no matter how it is positionedCenter of Gravity
Example: Bosu ball Exercise (the center of the body will always be the point) - 10A push or a pull; is equal to mass (m) * acceleration (a); has magnitude, direction and point of application; measured in Newtons (kg * m/s^2Force
Example: Biodex (leg ext) - 11Resistance to change; resistance to acceleration; tendency to remain in current stateInertia
Example: Plank (constant force) - 12Rotary (angular) or turning force; force when something is rotating; T= FdTorque
Example: Russian Twist - 13A quantity expressing the motion of a body or system, equal to the product of the mass of a body and its velocityMomentum

Vectors may be resolved into perpendicular (e.g. horizontal and vertical) components

Angular - 18Name the 4 steps of of Qualitative AnalysisPreparation
Observation
Evaluation
Intervention - 19What step of QA deals with obtaining pre-requisite knowledge, establishing the problem or chief complaint goalPlanning
- 20What step of the QA pertains to conducting the the analysisObservation
- 21This step of the QA is nothing the strengths and weaknesses of performance based on critical featuresEvaluation
- 22During this step of the QA is when instruction and corrective strategy is implementedIntervention
- 23What are the effects of squat depth on the capsule and ligaments of the kneeTightens joint capsules on anterior capsules and anterior drawer test
- 24What are the effects of the squat depth on the menisci and articular cartilageTibialfemoral compressive forces during knee flexion bear significant amounts of stress
Peak at 130 degress - 25What are the effects of squat depth on muscular development of the kneeThe effect on muscular development is at the hip and knee joint, particularly the Gluetus Maximus
The GM is increased significantly - 26Squat DepthPartial = 40 deg
Half = 70-100 deg
Deep = >100 - 27Squat StanceNarrow vs. wide to decrease tibiofemoral compressive forces; but narrow increase shear forces
Wide stance increases gluteus maximus and abductor longus activity - 28Spine During SquatFlexing the lumbar spine reduces tolerances to compressive loads
Extending the spine increases compressive loads on spine
Increases flexion with back squat (GM,HS)
Front squat= Quads - 29A combination of stability, balance, postural control, coordination and perceptionMovement and Function
(Basic Premise) - 30Name the 3 sources of dysfunctionDevelopmental Movement Dysfunction
Traumatic Movement Dysfunction
Acquired Movement Dysfunction - 31Type of dysfunction that occurs when growth and the command the command movement are not linearDysfunctional
- 32Type of dysfunction where injury or trauma is sourceTraumatic
- 33Type of dysfunction where unnatural activity repeated on a natural movement base and where natural activity repeated on an unnatural movement baseAcquired
- 34A developmental perspective and creates a systematic way to observe, rate, and rank movement patterns on on a numerical scale to focus on significant limitations or asymmetriesFunctional Movement Screening
- 35PRIMITIVE MOVEMENT PATTERNS 1: Basic mobility and stability movement patternsReciprocal reaching patterns

Address Asymmetries
Address score of 1 before a 2
Address most primitive patterns first - 51Common Mistakes in Prescribing CorrectivesProtocol Approach
Basic Kinesiology Approach
Appearance of Function Approach
Prehabilitation Approach - 52Common mistake in prescribing correctives is the one size fits all programming: weight loss, LBPProtocol Approach
- 53Common mistake in prescribing correctives is isolated target muscles approachBasic Kinesiology Approach
- 54Common mistake in prescribing correctives is to mimic function in poor wayAppearance of Function Approach
- 55Common mistake in prescribing correctives is arbitrary strengthening to prevent injuryPrehabilitation Approach
