Answer 1

achille tendon, foot arch, quadricep tendon

Answer 3

length, rate

Question 4

impact of high vertical movement in running (>10 cm)

Answer 4

dont contribute to forward motion, increase ground impact

Question 5

cause of high vertical movement

Answer 5

: Lack of forward lean, pushing off to early, excessive knee and ankle extension

Question 6

impact of low vertical movement < 5cm

Answer 6

Lack of flight in stride=dec power/pace

More time spent on ground, shorter stride

Question 7

Answer 7

the extension angles of thoracic and lumbar spine as well as an increase in the rotation of the lumbar spine during the stance phase

Question 8
