Results of the unbiased analysis. The bars represent mean values (± SEM) of physical activity (in counts per hour × 1,000) for the four time intervals of each of the four cycles in each of the five countries. Codes for the time intervals are listed in Table 2. The results of two-way ANOVAs are shown in Table 3. Asterisks indicate probabilities associated with the F statistics obtained in post hoc one-way ANOVAs for each panel: *** p < 0.0001, * p < 0.05. Absence of asterisks indicates p > 0.10. When the main effect is significant, significance of multiple comparisons by Tukey’s test is indicated by lower case letters: bars with different letters are significantly different from each other.
