- 4 Gait Analysis A Walking Or Running Up A Slope Should Take More Energy Than Walking Or Running On Level Ground Deri 1 (200.17 KiB) Viewed 38 times
than walking or running on level ground. Derive a formular for the
mechanical power that is needed for a person of mass m who is
walking or running up a slope at an angle 𝜃 at a constant velocity
v. (4 marks) b) For a person who weighs 50 kg estimate additional
metabolic power needed to walk and run up a slope of 20° (choose
appropriate velocities for walking and running speeds). How does
this estimate compare to walking or running on level ground? (6
marks) c) The estimate above will not be accurate for several
reasons. Detail these reasons and suggest an alternative method for
measuring the metabolic power needed to ascend and decent stairs.
(4 marks) d) Describe the following human gaits in terms of the
timing of the foots contact with the floor (ideally use a diagram
to illustrate). Distinguish between symmetrical and asymmetrical
gaits. • Walking • Running • Skipping • Hopping
