graphs

Question 1

what do you need for a pedotti graph

Answer 1

the vertical, anterior, posterior force components and the centre of pressure on the plane of interest for each movement.

Question 2

draw pedotti for heel strike

Question 3

draw pedotti for loading

Question 4

draw pedotti for midstance

Question 5

draw pedotti for push off

Question 6

draw pedotti for toe off

Question 7

when is vertical force greater than body weight

Answer 7

after 10% of gait cycle

Question 8

draw energy while walking

Question 9

what can be seen as a inverted pendulum model and what as a double

Answer 9

walking, our stance leg is inverted and the swing leg is double.

Question 10

when the freud number is above one what happends

Answer 10

the support limb comes off the ground.

Question 11

who will easily get thier freud number over zero

Answer 11

kids, as to why they have to run faster and short legs. or less gravity

Question 12

draw the energy while running

Question 13

heel strike running GRF draw.

Question 14

what happens in the heel strike GRF.

Answer 14

double peak in Fz, impact transient and push off. Fy shows braking and propulsion.

Question 15

draw farefoot running GRF.

Question 16

what happens in the farefoot GRF.

Answer 16

this is associated with carefoot/minimal shoe running. single peak: transiet rounded off by more gradual deceleration. load taken up by achilles rather than heel and compressive forces.

Question 17

draw the gastrocnemius medialis activation in farefoot anf heel foot running.

Question 18

draw the soleus activation in farefoot anf heel strike running.

Question 19

which calf activation is eccentric and which is concentric.

Answer 19

gastroc. high eccentric early in fore foot stride.
soleus high concentric activation mid stance in rarefoot stride.
