Chapter 3 Flashcards
in the upward phase triceps contract _
concentrically
knee internal rotation : 2
semimembranosis
semitendinosis
muscles that draw navel down toward spine: 4
TVA
multifidi
pelvic floor
quadratus lumborum
hip abduction: 3
gluteus maximus, medius
tensor fascia latae
weak scapular adductors = _ posture
kyphosis
muscles that initiate leg press:
knee extensors
hip extensors
muscles that initiate leg press : 2
knee extensors - quad fem, vastus 3
hip extensors - glutes, hamstrings
hip extension
- eccentric hip action =
- concentris hip action =
hamstrings
gluteus maximus
hip flexion
extend leg
Supraspinatis
Infraspinatus
Stabilizes, initiates abduction of arm
Stabilizes, externally rotates arm
G/H joint
Glenohumeral joint
Glenoid fossa and the humerus
A/c joint
Acromionclavicular joint
Acromion process and distal end of clavicle
S/T articulation
Also called:
Scapulothoracic articulation
Muscles and fascia that connect the scapula and the thorax
Shoulder girdle
muscles that produce small force production
longitudinal muscles
6 external rotators of the hip
Piriformis Superior gemellus Obturator interus Inferior gemellus Obturator externus Quadratis femoris
heels come off floor during squat
tight muscle: 2
gastrocnemius and soleus
S/C joint
Sternoclavicular joint
Sternum and the proximal end of the clavicle
client with recent hip replacement 3 considerations
lower body cannot support weight
all exercise should be performed in seated position
chais used should NOT have arm rests - increased ROM
Law of acceleration
Force acting on a body in a given direction is equal to body’s mass x body’s acceleration
muscles that produce large force production
penniform muscles
Hip flexion 4 muscles
Iliopsoas
Rectus femoris
Tensor fascia latae
Sartorius
muscles working eccentrically in downward phase of squat
glutes
hamstrings
prime mover hamstring curl
knee flexors - hamstrings
muscles active during plank: 4
TVA
multifidi
pelvic floor
quadratus lumborum
Kinetics
Study of biomechannical effects of internal/external forces on the body
hip internal rotators: 6
adductor longus, brevis, magnus
gluteus minimus
pectineus
tensor fascia latae
foot slaps the ground
weak muscle
anterior compartment - dorsiflexors
hip flexion
4 muscles
iliopsoas
rectus femoris
sartorius
tensor fascia latae
3 factors associated with muscular balance
Equal strength and flexibility btwn right and left side
Proportionate ratio of strength btwn agonist and antagonist
Balanced flexibility that results in full range of joint motion
knee extension muscles -
quadriceps femoris vastus: lateralis intermedius medialis
standing on one leg:
balance leg collapses in
tight muscle
weak muscles
tight - hip adductors
weak - gluteus minimus, medius
knee external rotation muscles
biceps femoris
knee flexion muscles
concentric movement =
hamstrings
flexion
