Foundations of Movement and Healthy Eating Flashcards
What is the kinetic chain?
The concept that joints and segments have an effect on one another during movement.
What is joint stability?
The ability to maintain or control joint movement or position.
What is joint mobility?
The range of uninhibited movement around a joint or body segment.
Which parts of the kinetic chain tend to favor stability?
Scapulothoracic
Lumbar Spine
Knee
Foot
Which parts of the kinetic chain tend to favor mobility?
Glenohumeral
Thoracic Spine
Hip
Ankle
What is the foot transition relating to stability during the gait cycle?
From heel strike to accepting body weight moves into pronation, forfeiting some stability in exchange for mobility.
As it pushes off, moves back into supination, favoring stability.
What is a closed chain exercise?
The end of the chain farthest from the body is fixed and the rest of the chain moves.
What are some examples of closed chain exercises?
Squats (feet fixed on ground)
Push-ups
Pull-ups
What is an open-chain movement?
The end of the chain farthest from the body is free to move and not fixed on a surface.
What are some open-chain exercises?
Bench press
Hamstring curls
Biceps curls
Shoulder press
How can a determination be made about open-close chain exercises considering force applied?
Closed-chain - Force applied to surface, body moves instead of equipment.
Open-chain - Force applied moves the limb farthest from body as well as weight of equipment.
What are shearing forces in open-chain exercises?
Forces that work in opposite directions, causing slippage.
What are some advantages of closed chain over open chain exercises?
Closed chain emphasizes compression of joints, helping with stabilization.
Closed-chain involve more muscles and joints, leading to better neuromuscular coordination.
What are the three planes of motion for human movement?
Sagittal Plane
Frontal Plane
Transverse Plane
What are four movements associated with the Sagittal Plane?
Flexion
Extension
Plantar flexion
Dorsiflexion
What is the Sagittal Plane?
The longitudinal plane that divides the body into right and left portions.
What is the transverse plane?
Anatomical term for the imaginary line that divides the body, or any of its parts, into upper (superior) and lower (inferior) parts.
What is the transverse plane also known as?
The horizontal plane
What is the frontal plane?
A longitudinal section that runs at a right angle to the sagittal plane, dividing the body into anterior and posterior positions.
What movements occur along the Sagittal plane?
Forward and backward movements.
What is flexion?
Decreasing the angle between two bones.
What is Extension?
Increasing the angle between two bones.
What is plantar flexion?
Moving the sole of the foot downward
What is dorsiflexion?
Moving the top of the foot toward the shin.
What are some examples of Sagittal plane exercises?
Squat, lunge, crunch, biceps curl, basic step, front kick, chair pose.
What type of movements occur along the Frontal Plane?
Lateral Movements
What are some of the movements along the frontal plane?
Abduction
Adduction
Lateral flexion
Elevation
Depression
Inversion
Eversion
What is the abduction movement?
Motion away from the midline of the body (or body segment).
What is the adduction movement?
Motion toward the midline of the body (or body segment).
What is lateral flexion?
Bending of the neck or trunk to the left of right side.
What is the elevation movement?
Moving to a superior position (scapula), eg. when the shoulder blades or scapula moves up.
What is the depression movement?
Moving to an inferior position (scapula), the shoulder blades move down.
What is the inversion movement?
The lifting of the medial border of the foot (subtalar joint), rolling the foot outward
What is the eversion movement?
Lifting the lateral border of the foot (subtalar joint), rolling the foot inward.
What are some exercises using the frontal plane?
Jumping jack, lateral lunge, lateral raise, side step, side kick
What types of movements occur along the transvers plane?
Rotational or twisting movements.
What are some movements along the transverse plane?
Rotation
Pronation (hand)
Supination (hand)
Horizontal flexion (adduction)
Horizontal extension (abduction)
What is a rotation in the transverse plane?
Inward or outward turning about the vertical axis of a bone.
What is Pronation (hand)?
Rotating the hand and wrist medially (Palm down)
What is Supination (hand)?
Rotating the hand and wrist laterally (palm up)
What is horizontal flexion (adduction)?
From a 90 degree horizontally abducted shoulder or hip position, the humerus or femur is flexed (adducted) in to the body.
What is horizontal extension (abduction)?
From a 90-degree (horizontally flexed shoulder or hip position, humerus or femur is extended out or away from the body.
