Fig. 1. DBP and HR (mean, standard error) during the daytime and evening for work and off days. Bars designated with the same letter (a-a; b-b; c-c) represent values that significantly differ from one another. The decrease in DBP from work to off days was significantly greater in the daytime than in the evening; and the decrease in HR from daytime to evening was significantly greater during work than off days. (Significance indicates p < .05 with Bonferroni correction).
