Comparison of the nondimensional, mean values of approximations \(\widetilde{\Delta L}_{\max }\), \(\widetilde{T}_\mathrm{{c}}\) and \(\widetilde{\Delta \theta }_2\), given by formulas (7), (5) and (8), respectively, with the mean values of the experimental data for these running parameters (measured and appropriately normalized). The means were calculated for the sample of \(n = 105\) runners
