Part 1: Chp. 3 Flashcards
kinetic chain
the concept that joints and segments have an effect on one another during movement
joint stability
ability to maintain or control joint movement or position, achieved by joint structure (ligaments and joint capsules) and the neuromuscular system
joint capsules
a ligamentous sac that surrounds the articular cavity of a freely movable joint
pronation
internal rotation of the forearm causing radius to cross diagonally over the ulna and palm to face posteriorly
example of pronation in feet
as foot transitions from heel strike to full body weight it pronates and forfeit some stability in exchange for mobility to absorb impact
supination
external rotation of the forearm that causes palm to face anteriorly
example of supination in feet
as foot pushes off, ankle moves back to supination to become rigid and stable again
Shoulder (stability or mobility and name)
glenohumeral for mobility
Shoulder Blade (stability or mobility and name)
scapulothoracic for stability
Thoracic spine (stability or mobility)
mobility
Lumbar spine (stability or mobility)

Hip (stability or mobility)

Knee (stability or mobility)

Ankle (stability or mobility)

Foot (stability or mobility)
stability
Planes of motion
describes anatomical movement in sagittal, transverse and frontal
Sagittal Plane
longitudinal plane that divides the body into right and left
Frontal Plane
longitudinal section that runs at a right angle to sagittal plane (anterior/posterior planes)
Transverse Plane
division of body into superior and inferior parts
Superior
upper
Inferior
lower
joint actions of sagittal plane
flexion, extension, plantar flexion, dorsiflexion
joint actions of frontal plane
abduction, adduction, ankle eversion and inversion
joint actions of transverse plane
rotation, horizontal shoulder adduction and abduction
five primary movement patterns
bend and lift, single leg movements, upper body pushing, upper body pulling, rotational movements
Principle of balancing a workout
Cardiorespiratory, strength, flexibility, and neuromuscular
agonist
muscle responsible for observed movement
antagonist
muscle acts in opposite to contraction
carbohydrates
the body’s preferred energy source from simple sugars, grains, rice, potatoes, beans
stored of glycogen in muscles and liver that is transported to the blood as glucose which is easy for the body to break down and provide quick energy
proteins
a compound composed of 20 amino acids not used for energy
glucose
a simple, sugar, that form that all carbs are used as energy
triglycerides
three fatty acids joined to a glycerol backbone, how fat is stored
Adenosine Triphosphate (ATP)
basic substance the body used for energy
a high energy phosphate molecule required to provide energy for cellular function, produced aerobically and anaerobically
Creatine Phosphate
used for extreme intensities for a second
Glycotic Anaerobic System
used for high intensities for a few seconds, can produce ATP without oxygen
Aerobic system
energy used when moderate or low intensities are performed and use carbs and fats to produce ATP
Three Zone Intensity of Model
Zone 1: easily talk
Zone 2: talking is challenging
Zone 3: Cannot talk
Each zone is separated by the First Ventilatory Threshold and the Second Ventilatory Threshold
Functional Movement and Resistance Training IFT
1: Stability and Mobility - correct imbalances
2: Movement Training - movement with body weight
3: Load Training - external resistance
4: Performance Training - improve power and speed
