What is the #1 cause of injury
previous history of injury
Do we care more about symmetry or efficiency for each individual
effeciency
What are the task related determinants for running
• shock absorption • adequate pelvic/trunk alignment and stability • adequate limb alignment and stability • adequate foot alignment and stability
What are the phases for running
right heel strike midstance toe off double limb unsupported left heel strike mid stance double limb unsupported right heel strike
stance phase is what percent of running cycle
40%
swing phase is what percent of running cycle
30%
float is what percent of running cycle
15% x2
Where is the joint
kinematics
what forces are the body under
kinetics
Does the big toe matter?
yes we need about 30 degrees of extension for running form
Impact peak is what and how much magnitude
1.5 times body weight immediate compression at 5% of running cycle
When does impact peak increase
with downhill running
Can impact peak change and what are we focused on for the graph
yes it can change we are worried about the slope (Rate) of the ground force reaction
what is active peak and its magnitude and does it change much
2.5 times body weight and doesn’t change much
When you are running and your foot first hits the ground what is the anterior to posterior GFR
breaking impulse posterior
When you start to go into swing phase where is the anterior to posterior GFR
anterior propulsive impuse
medial to lateral GFR is the most ______
variable
What does internal torque mean?
result of the muscles generated forces responding to gravity
What is the area under a power curve
mechanical work
What is positive work
concentric
What is negative work
eccentric
What is the path of center of pressure
runners strike from posterior lateral to anterior medial
When you are analyzing running gait what should you start with
side view
What 7 can you observe from side view
foot strike pattern tibial angle knee flexion during stance hip extension late stance trunk lean overstride vertical displacement
