The Effect of Acute Beetroot Juice Supplementation on Anaerobic Performance in Football Players

NCT07048912 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 16

No results posted yet for this study

Summary

The aim of this clinical trial is to examine the effects of two different natural fruit-vegetable blend beverages on short-duration, high-intensity exercise performance and muscle oxygenation in young male football players. The study also investigates how these beverages influence certain metabolic responses. The main questions it seeks to answer are:

* Does one of the beverages improve peak and mean power output during the Wingate test?
* How do these beverages affect muscle oxygenation and post-exercise recovery?
* Researchers will compare the effects of the two beverages on performance and metabolic markers.

Participants:

* Consume one of the two natural beverages 2.5 hours before testing (assigned at random)
* Perform a 30-second high-intensity Wingate cycling test
* Undergo measurements of muscle oxygenation, heart rate, blood pressure, blood lactate, and blood glucose during and after exercise
* Maintain consistent dietary and physical activity routines and avoid certain foods prior to testing

Interventions

DIETARY_SUPPLEMENT

Beetroot Juice (BJ)

This intervention involves a single 140 mL dose of a commercially available concentrated beetroot juice supplement (Beet-It Pro Elite Shot, James White Drinks Ltd., UK), containing approximately 12.8 mmol (800 mg) of dietary nitrate. Participants consume the juice 2.5 hours prior to performing a 30-second Wingate anaerobic test. The purpose of this intervention is to examine its acute effects on anaerobic performance, muscle oxygenation, and metabolic responses.

DIETARY_SUPPLEMENT

Blackcurrant Juice (Placebo)

This intervention involves a single 140 mL dose of a low-calorie blackcurrant juice (Pfanner, Austria) with negligible nitrate content (\<0.1 mmol). The placebo is matched to beetroot juice in appearance, taste, and packaging to ensure double-blind conditions. It is consumed 2.5 hours before the Wingate test and serves as the control condition.
