Fig. 7. Recordings such as those depicted in Fig. 5, showing an extreme case in which loading results in t_pk- being reduced to zero and in an increase in the instantaneous recovery of mechanical energy r(t) during the descent of the centre of mass to a level equal to that attained during the lift. This leads to very high values of pendular recovery during the step (African woman, Luo, 88.9 kg, 4.5 km h^-1, loaded with 19.1 kg). For further details, see legend to Fig. 5.
