Runnin Flashcards
What is the number one cause of injury in runners?
History of previous injury
What are the four task related determinants?
Shock absorption (1), adequate alignment and stability of the pelvis/trunk(2), limb(3), foot(4)
What are the running stride cycle-phases? (4)
Stance (40%)
Float (15%)
Swing (30%)
Float (15%)
What percentage does the stance phase make up in the running stride cycle? Walking?
Running -40%
Walking-65%
What critical event indicates a person is in the float phase of running? How long (%) is a person typically in 1 part of the float phase?
Double limb unsupported
15%
What are three components of frontal plane kinematics?
Pelvic obliquity/drop
Hip joint ab/adduction
Subtalar inversion/eversion
What are the two components of transverse plane kinematics?
Pelvic rotation
Hip IR/ER
T/F: Barefoot runners are more likely to forefoot strike than rearfoot strike.
True
T/F: Among Shod runners, there is a higher rate of midfoot strikers compared to rearfoot strikers.
False. Rearfoot= 75-80%. Midfoot= 24%
T/F: Regardless of strike pattern, the ankle typically has the highest positive work/average power?
True
What is the expected degree of flexion seen at the knee at foot strike?
20 degrees
When looking at runners from the posterior view, what is able to be observed? (6)
Step width, heel eversion (pronation), foot progression angle, heel whip, knee window, pelvic drop
What are four major pathologies seen in runners?
Patllelofemoral pain syndrome
IT band syndrome
Medial tibial stress syndrome
Plantar fasciitis
Do barefoot runners have a higher or lower ankle stiffness compared to shod runners?
Lower
Do barefoot runners have a higher or lower energy efficiency during ground collision compared to shod runners?
Higher
