Current themes in running

Question 1

What is the argument for barefoot running?

Answer 1

through evolution runners were barefoot

habitual barefoot runners fore-foot strike

Question 2

why is running barefoot potentially beneficial?

Answer 2

potentially reduce peak impact force and loading rates

reduce injury

Question 3

What does running bare foot make some heel-strike runners do?

Answer 3

change there strike pattern to mid or fore-foot striking

this may be the reason or the changes in results rather than the shoe

Question 4

How does surface effect impact levels?

Answer 4

it doesn’t change it as humans naturally change their technique based on the surface

Question 5

What injury’s can higher (instantaneous) loading rates potentially lead to?

Answer 5

Tibia stress fractures (Milner 2006)

Plantar fasciitis (Pohl, Hamill & Davis 2009)

Question 6

What did prospective study looking at heel strike runners over 2 years find?

Answer 6

no difference in force variable (GRF)

Injury group had higher vertical impact and peak and loading rate

Question 7

How can patellofemoral pain PFP be reduced

Answer 7

change running pattern to fore-foot strike (reduces impact peak & loading rate)
