What does the Nike Vaporfly 4% do
Stablises ankle
Keeps toe straight
Midsole high degree compliance and resilience
What is qualitative research
Examples
Non Numeric
Unstructed/semistructured
e.g. Colour, oberservation, notes and images
What is quantitative research
Example
Numeric
Structured
e.g. Height, weight, shoe size, test, surveys, experiments
What does 1 plane look like
A——————————-B
What does 2 plane look like
C
A B
What are the 3 different planes of human motion
Sagittal
Transverse (horizontal plane)
Frontal (coronal plane)
Planes are…
What occurs inside a plane
2 dimensional surfaces
Movement
Sagittal plane involves
Lateral, medial
Flexion/extension
Transverse plane involves
Longitudinal
Superior/inferior
Twisting/rotating
Frontal plane involves
Anterior/posterior
Adduction/abduction
What is a axis
The hinge or the pivot point around which movement occurs
What are the three axis and what plane is it connected to
Mediolateral axis = sagittal
Anteroposterior axis = frontal
Longitudinal axis = transverse
What type of movement occurs in the sagittal plane
What axis
Example
Flexion and extension
Mediolateral axis
Plantar flexion
Dorsi Flexion
What is flexion
Bending movement
Angle between a segment and proximal segment DECREASES
What is extension
Straightening movement
Angle between a segment and its proximal segment INCREASES
What type of movement occurs in transverse plane
What axis
Example
Internal and external rotation
Longitudinal axis
Twisting at the write - supernation and pronation
What is internal rotation
Also known as
Limb rotates towards the MIDLINE of the body
Medial rotation
What is external rotation
Also known as
Limb rotates towards the OUTSIDE or LATERAL SIDE of the body
Lateral rotation
What type of movement occurs in the frontal place
What axis
Example (hard)
Adduction and Abduction
Anteroposterior axis
Trunk and head lateral flexion
Head, ulnar and radial deviation
What is ADDuction
Movement TOWARDS MIDLINE
“Youre ADDing to your spine”
What is ABduction
Movement AWAY from the MIDLINE
What movements can occur at the HIP JOINT
Flexion-extension
Adbuction-Adduction
Internal-external rotation
What movements can occur at the KNEE JOINT
Flexion-extension
Internal-external rotation
What movements can occur at the ANKLE JOINT
Plantar flexion - dorsi flexion
Inversion - eversion
Medial - lateral rotation
