Regression analysis coefficient for all cardiovascular variables based on the following equation:

${\mathrm{\left(}\mathrm{\text{CV Variable}}\mathrm{\right)}}_{\mathrm{i}\mathrm{j}}\mathrm{=}{\mathrm{\rho }}_{\mathit{i}}\mathrm{+}{\mathrm{\beta }}_{\mathrm{1}}\mathrm{\left(}{\mathit{A}\mathit{G}}^{\mathrm{2}}\mathrm{\right)}\mathrm{+}{\mathrm{\beta }}_{\mathrm{2}}\mathrm{\left(}\mathit{A}\mathit{G}\mathrm{\right)}\mathrm{+}{\mathrm{\beta }}_{\mathrm{3}}\mathrm{\left(}{\mathit{W}\mathit{R}}^{\mathrm{2}}\mathrm{\right)}\mathrm{+}\mathrm{+}{\mathrm{\beta }}_{\mathrm{4}}\mathrm{\left(}\mathit{W}\mathit{R}\mathrm{\right)}\mathrm{+}{\mathrm{\beta }}_{\mathrm{5}}\mathrm{\left(}{\mathit{A}\mathit{G}}^{\mathrm{*}}\mathit{W}\mathit{R}\mathrm{\right)}\mathrm{+}{\mathrm{\epsilon }}_{\mathit{i}\mathit{j.}}$

AG, artificial gravity level; WR, work rate. Only the significant parameters (p < 0.05) were included in the regression. A graphical representation of these results is shown in Figure 5. NS, non-significant.
