Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Does daily beetroot juice supplementation change VO2 max in fasting individuals during the first week of Ramadan?
Participants will:
Visit the lab before the start of Ramadan and after one week of fasting If assigned to intervention group, consume daily shots of beetroot juice (70ml) during the first week of Ramadan fasting Perform maximal exercise testing on a cycle ergometer

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
24 young healthy adults will be recruited to undergo these two visits. The first visit will assess maximal oxygen uptake to determine aerobic fitness and metabolic exercise intensity zones under non-fasting conditions. The second visit will be completed after one week of Ramadan fasting. If assigned to the intervention group, participants will consume one shot (70ml) of Blonyx - Beet It Sport Nitrate 400 beetroot juice every day. Each shot contains 400mg of nitrates. Urine Specific Gravity will be measured after each visit to assess hydration status. The intervention group will also undergo Single Blood Draws after each visit to assess nitrate concentrations before and after a week of consumption.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
No Intervention
Normal Fasting, no intervention. During this arm, participants will be asked to complete an exercise test before and after 1 week of Ramadan fasting.
No interventions assigned to this group
Nitrate Supplementation
Participants will be asked to consume daily nitrate supplementation (70ml) in the form of beetroot juice for 7 days. Participants will then complete a maximal exercise test as they fast.
Beetroot Juice (Beet-It Stamina Shot) & Supervised Exercise Training
7 doses, taken daily, 70 ml shots, consumed in the morning before the start of fasting
