Chapter 3: Foundations of Movement & Healthy Eating Flashcards
Closed Chain Movement
the end of the chain farthest away from the body is fixed
ex. squat, push up, pull up
open chain movement
end of the chain farthest away from the body is free to move and not fixed
ex. hamstring curl, bench press, bicep curl, shoulder press
Sagittal plane
- separates the body into right and left halves. Forward and backward movements
ex. squat, lunge, crunch , bicep curl
Flexion
decreasing the angle between two bones
(sagital plane)
extension
increasing the angle between two bones
(sagital plane)
plantar flexion
moving the sole of the foot downward
(sagital plane)
Dorsiflexion
moving the top of the foot toward the shin
(sagital plane)
frontal plane
separates the body into anterior and posterior halves, lateral movements
ex. jumping jack, lateral lunge, lateral raise
Abduction
Motion away from the midline of the body
(frontal plane)
Adduction
Motion toward the midline of the body
(frontal plane)
Lateral Flexion
Bending of the neck or trunk to the left or right side
(frontal plane)
Elevation
Moving to a superior position
(frontal plane)
Depression
Moving to an inferior position
(frontal plane)
Inversion
lifting the medial border of the foot
(frontal plane)
Eversion
lifting the lateral board of the foot
(frontal plane)
Transverse Plane
Divides the body into upper and lower parts, rotational or twisting movements
ex. supine bicycle crunch, cross punch
Rotation
Inward or outward turning about the vertical axis of a bone
(transverse plane)
Pronation
rotating the hand and wrist medially (palm down)
(transverse plane)
Supination
Rotating the hand and wrist laterally (palm up)
(transverse plane)
Horizontal flexion
from a 90-degree horizontally abducted shoulder or hip position, the humerus or femur, respectively is flexed in toward the midline of the body
(transverse plane)
Horizontal extension
from a 90-degree flexed shoulder or hip position, the humerus or femur, respectively, is extended out away from the midline of the body
(transverse plane)
Multiplanar
Combined movements that occur in multiple planes of motion. Think of combining two or more movements described above to create one, integrated whole movement
ex. lunge with trunk rotation, squat with lateral raise
Circumduction
cone shaped movements combining flexion, extension, and adduction in sequential order
(multiplanar)
opposition
thumb movement unique to humans and primates
(multiplanar)
Pronation
combined eversion, abduction, and dorsiflexion
(multiplanar)
supination
combined inversion, adduction, and plantar flexion
(multiplanar)
Five Primary Movement Patterns:
bend and lift, single leg, push, pull, rotation
Muscles that act at foot/ankle: Anterior tibialis
dorsiflexion at ankle, inversion at foot
Muscles that act at foot/ankle: peroneus longus
plantar flexion at ankle, eversion at foot
Muscles that act at foot/ankle: peroneus brevis
plantar flexion at ankle, eversion at foot
Muscles that act at foot/ankle: gastrocnemius
plantar flexion at ankle, flexion at knee
Muscles that act at foot/ankle: soleus
plantar flexion at ankle
Muscles that act at foot/ankle: posterior tibialis
plantar flexion at ankle, inversion of foot
Muscles that act at foot/ankle: extensor hallucis longus
dorsiflexion and inversion of the foot, extension of the great toe
Muscles that act at foot/ankle: extensor digitorum longus
dorsiflexion and eversion of foot, extension of toes 2 through 5
Muscles that act at foot/ankle: peroneus tertius
dorsiflexion and eversion of the foot
Muscles that act at foot/ankle: plantaris
flexion of the knee, plantar flexion of the ankle
Muscles that act at foot/ankle: flexor hallucis longus
flexion of the great toe, plantar flexion of the ankle, inversion of the foot
Muscles that act at foot/ankle: flexor digitorum longus
flexion of toes 2 through 5, plantar flexion of the ankle, inversion of the foot.
Muscles that act at knee: rectus femoris
extension
Muscles that act at knee: vastus lateralis, intermedius, and medialis
extension
Muscles that act at knee: biceps femoris
flexion and external rotation
