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.
