Experimental sequence and testing protocols
Subjects reported to the laboratory 4 h post-prandial for two
separate testing sessions, at least two days apart at roughly the
same time of day. Each testing session consisted of a continuous,
incremental exercise bout of running on a treadmill (18–60, Quinton,
Seattle, WA) or cycling on an ergometer (Monark 886, Varberg,
Sweden) to determine maximal aerobic capacity. To reduce the
possibility of an order effect, assignment of exercise mode was
counterbalanced. During the maximal exercise tests subjects were
