Table 3: Endothelial markers pre- and post-ride.

	PRE (M/F)	IP (M/F)
ET-1	1.1 ± 0.4 (1.1/1.1)	2.5 ± 1.0^*(2..4/2.7)
P-selectin	87 ± 23 (89/81)	111 ± 29^* (118/90^a)
ICAM1	205 ± 48 (211/185)	219 ± 52^* (229/186^a)

Values are means and standard deviation; Inside parentheses (average of Males/Females); PRE Pre-ride; IP Immediate post-ride; M Males; Females; ET-1 Endothelian-1; ICAM1 intercellular adhesion molecule 1; ^* significantly different from PRE, (p < 0.05); ^a significantly different from males.
