office project 2007 activation 11
Third, activation dynamics was neglected in the formulation of the static optimisation problem posed in this study. Although activation dynamics does not have a significant effect at slow running speeds (Lin et al., 2012), its role in faster running may be more pronounced. For example, Neptune and Kautz (Neptune and Kautz, 2001) emphasised the importance of the electromechanical delay by showing that it is needed to realistically simulate the optimal cadence performance in high frequency pedalling. However, the values of activation and deactivation time constants used in model simulations reported in the literature have ranged from 10 to 22 ms and 30 to 200 ms, respectively (Anderson and Pandy, 2001; Chumanov et al., 2007; Seth and Pandy, 2007; Zajac, 1989). Future work should be directed at gaining a better understanding of: (1) the dynamics of the rise and fall of active muscle force using isolated muscle-fibre experiments; and (2) the extent to which different values of activation and deactivation time constants affect model predictions of muscle force, particularly in simulations of ballistic motor tasks. In any event, we do not believe the conclusions obtained in this study are affected by neglecting muscle activation dynamics in the model because the patterns of predicted muscle activations and muscle forces agree, at least qualitatively, with the sequence and timing of measured EMG activity (supplementary material Fig. S4). 2ff7e9595c
