Comparison of swimming speeds (µm s−1) vs dimensional time (s). (a) average path velocity (VAP) for the three tensile stiffness coefficients S1 with CatSper mediated Ca2+ dynamics and with constant Ca2+. (b) curvilinear velocity (VCL) for the three tensile stiffness coefficients S1 using VA=0.3 and VA=0.45. For all simulations kA=0.3 if ζ(s, t) > 0 and kA = 0.5 if ζ(s, t) < 0.
