Scientists have developed an apparatus (Fig. 7.1) to physically support a subject during walking and running such that gravitational acceleration acting on the subject is cut in half. If the subject is an average sized human, calculate the optimal stride frequency during walking when using the apparatus.

Answer: The stride frequency when walking with the apparatus is 0.44sec?1 .
