Fig. 4.
Group mean diastolic (A) and systolic (B) blood pressures, heart rate (HR; C), and oxygen consumption (VO2; D) prior to and following consumption of a BR (●) or PL (○) beverage. Three hours/CPX base indicates the time point 3 h following beverage consumption, which was also at rest just prior to commencement of the CPX. The dashed vertical lines represent the start and end of exercise. CPX stages 2 (2 mph/2%) and 4 (2 mph/6%) indicate stages of the CPX when measures were taken. Stages 2 and 4 are measures that are matched for work level. Peak indicates the measure taken immediately prior to test termination (which was at a different intensity for BR or PL). The measures taken at time points after time to exhaustion are 2- and 6-min recovery. Values are group mean ± SE. *significantly different from PL group, P ≤ 0.05; **significantly different from PL group, P ≤ 0.01.
