Fig. 2From: The Night-Time Sleep and Autonomic Activity of Male and Female Professional Road Cyclists Competing in the Tour de France and Tour de France FemmesTraining impulse (TRIMP) and daily strain of male cyclists during the Tour de France plotted as a function of day of race (panels a and c) and week of race (panels b and d). AU, arbitrary units. ‘B’ represents the baseline mean calculated at least one week prior to the first day of the race; ‘P’ indicates the post-race mean calculated from post-race night 2 to post-race night 9; ‘R’ indicates rest days; ‘T’ indicates individual time trial; ‘F’ indicates flat stages; ‘H’ indicates hilly stages; ‘M’ indicates mountain stages. Data are presented as mean (bars) and 95% confidence intervals (error bars). Closed circles represent individual cyclists. In the panel a for TRIMP, the results of the post-hoc analysis are not shown. In panels c and d for daily strain, * indicates a significant difference from baseline (p < .05)Back to article page
