Gait analysis. a) Walking or running up a slope should take more energy 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 0 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 (6 marks)
