Subjects will consume a 75g glucose beverage three times daily for seven days while participating in five structured aerobic exercise sessions throughout the experimental protocol.
Subjects will complete 45 minutes of recumbent cycling at 60-65% of age-predicted maximal heart rate five times over seven days while ingesting a 75g glucose beverage three times daily.
Active Comparator: GLU
Subjects will consume a 75g glucose beverage three times daily for seven days without participating in structured aerobic exercise.
Dietary Supplement: GLU
Subjects will consume a 75g glucose beverage three times daily over a seven-day period.
- Change in Vascular Endothelial Function [ Time Frame: Before and after the seven-day intervention in both groups. ]Brachial artery flow-mediated dilation (%), measured via Doppler ultrasound, will be assessed before and after the intervention.
- Central Blood Pressure [ Time Frame: Before and after the seven-day intervention in both groups. ]Aortic blood pressure will be derived from radial artery pressure wave measurements (via applanation tonometry) during resting conditions.
- Physical Activity [ Time Frame: Continuously throughout the seven-day intervention. ]Steps per day will be recorded via accelerometry throughout the intervention in both groups.
- Caloric Consumption [ Time Frame: Continuously throughout the seven-day intervention. ]Subjects will record their dietary intake throughout the intervention.
