Estimates of the simple linear regressions (y = β1 × x + 100) calculated to observe the trend of the SE (dependent variable, y) over time (independent variable, x) from the initial condition at the beginning of the experimental period (SE = 100) for the basal states. A significant regression equation was found in C1 (F (1, 6) = 68.65, p < 0.001), with an R2 of 0.919. A significant regression equation was not found in C2. A significant regression equation was found in C3 (F (1, 6) = 12.46, p < 0.05), with an R2 of 0.675. A significant regression equation was not found in C4.
