Midterm 1 Flashcards
physical activity
any movement (muscles using energy to contract)
exercise
structured activity to see improvements in a specific area
physical fitness
traits we possess but can also improve on (flexibility, etc)
map trends in america
-overall physical inactivity has increased over time
-obesity has increased over time
personal trainer scope of practice
-screen and interview potential clients
-perform fitness tests or assessments
-help clients set goals and provide motivation
-develop exercise programs
-demonstrate and instruct specific techniques
-provide clients with safe and effective exercise techniques and programs
-supervise or “spot” clients when they are performing exercises
-maintain records of client progress
-be knowledgeable resource
-educate clients
ipsilateral
same side of the body (right arm right leg)
contralateral
opposite sides of the body
prone
face down
supine
laying on back with face up
valgus
distal end of segment rotates laterally (knock knees)
varus
distal end of segment rotates medially (bow legged)
sagittal plane
cuts left from right
frontal plane
cuts back of body from the front of the body
transverse plane
cuts the top of the body from the bottom
fibrous joints
immovable
cartilagenous joint
semi movable, bone->cartilage->bone
synovial joint
freely moveable, has a synovial cavity filled with synovial fluid as well as synovial membrane that all allows for most movement
what does not regrow
cartilage

-flexion/extension
-lateral R/L flexion
-circumduction
-protraction/retraction

-R/L rotation
-flexion/extension
-lateral R/L flexion
glenohumeral joint actions
-internal/external rotation
-flexion/extension
-abduction/adduction
-horizontal ab/adduction
-circumduction
elbow joint actions

-horizontal abduction/adduction
knee joint actions
flexion/extension
ankle joint actions
-circumduction
-inversion/eversion
-dorsi/plantar flexion
isotonic contraction
-concentric and eccentric phase
-muscle length changes or joint angle changes
isometric contraction
no joint angle or muscle length change, muscle contracts but does not shorted
concentric phase
struggle phase, muscles shortening, joint angle decreases
eccentric phase
relax phase, muscles lengthening, joint angle increases
muscle roles
-agonist: prime mover
-antagonist: opposing group
-synergists: provide support and unwanted movement
-stabilizers: help stabilize body during movement
