5) In a walking human, there is a maximum plantar flexor moment of 90 N.m during push-off a. To which muscle group would you attribute this moment and why might it not fully reflect the force in those muscles? b. This total moment results in a net moment of 30 N.m. Explain the effect this will have and justify your prediction using the laws of motion c. Which other parameter would you need to know in order to determine maximum joint power at the ankle during push-off, and what factors would determine the maximum power that could be produced
