Note. Data presented represent the average value for each day of the week calculated from original 21 days of data. Data are presented as median (interquartile range).
Note. Superscript 'a' represents days which are significantly different from Sunday; 'b' represents different from Monday; 'c' represents different from Tuesday; 'd' represents different from Wednesday; 'e' represents different from Thursday; 'f' represents different from Friday; and 'g' represents different from Saturday. Significant differences determined using Repeated Measures Analysis of Variance (log transformation was used on data for all days for analysis where data were non-normally distributed). p < .05 was used for statistical significance.
