Q

what critical events are occuring at MSt for running?

A
  • swing limb passes stance
  • COM in front of stance foot
  • COM at lowest point
  • knee moving into extension

16
Q

what provides a stable platform for the BW to pass over in MSt for running?

A

foot and leg // all BW is borne by a single leg and the lower limb is usually more susceptible to injury

17
Q

In MSt for running, what is the foot doing (or stopping)?

A

pronating // if foot is still pronating then there’s too much movement and instability

18
Q

how does the weight of the body affect the foot in MSt for running?

A

BW has a flattening effect on the arch of the foot

19
Q

where is the force dissipated over time in running (IC/MSt)?

A
  • achilles tendon
  • plantar fascia
  • quad mechanism
  • hip ABductors
20
Q

what is the Windlass Mechanism?

A

as grt toe extends - plantar fascia tightens and raises arch of foot

21
Q

what critical events are occuring at Take Off for running?

A
  • majority of forward propulsion of body coming from swing leg and arms
  • max hip extension
  • passive knee extension
  • rapid tibial advancement over foot
  • foot provides rigid lever
  • opposite leg in maximum lift
22
Q

what critical events are occuring at initial swing for running?

A
  • COM displaced upward and forward
  • rapid active hip flexion
  • hip adduction maintains line of progression
  • rapid knee flexion
  • active ankle DF
23
Q

what critical events are occuring at MSw for running?

A
  • COM reaches highest point
  • active hip flexion peaks
  • hip adduction continues
24
Q

what critical events are occuring at TSw?

A
  • COM is displaced downward
  • active hip extension
  • hip adductors prepare for foot placement
  • knee rapidly extends
  • progressive dorsiflexion
25
Q

what ankle joint adaptations are required for running?

A
  • increased PF/DF + pronation/supination
26
Q

what knee joint adaptations are required for running?

A
  • increased flexion in early stance and swing
27
Q

what hip joint adaptations are required for running?

A

increased flexion and extension

28
Q

what pelvid joint adaptations are required for running?

A

increased transverse plane rotation

29
Q

what arm joint adaptations are required for running?

A

increased shoulder ROM
increased elbow flexion
