Enhancing satiety and aerobic performance with beer microparticles-based non-alcoholic drinks: exploring dose and...

Area of Science:

• Sports Science
• Nutritional Science
• Biochemistry

Background:

• Beer, a popular alcoholic beverage, contains carbohydrates, amino acids, vitamins, and polyphenols.
• The use of beer for post-exercise fluid replacement is debated.
• A non-alcoholic pale ale microparticle beverage (PABM) was developed, but its phenolic profile and ergogenic effects were uncharacterized.

Purpose of the Study:

• To investigate the ergogenic potential of PABM in male Wistar rats.
• To determine the phenolic composition of PABM.
• To assess the impact of PABM on running performance and satiety.

Main Methods:

• PABM was prepared using spray-dried beer microparticles.
• Rats underwent a treadmill training protocol with daily gavage of PABM (20 or 200 mg/kg) or water.
• Phenolic profile was analyzed using high-performance liquid chromatography and mass spectrometry.

Main Results:

• Chlorogenic acid was identified as the primary phenolic compound in PABM.
• A low dose (20 mg/kg) of PABM increased aerobic performance after 4 weeks.
• This performance enhancement was negated at 8 weeks, and a higher dose (200 mg/kg) blunted the effect.
• The higher dose also reduced food intake, suggesting an impact on satiety.

Conclusions:

• PABM demonstrates potential for improving aerobic performance and satiety.
• The ergogenic and satiating effects are dose-dependent and time-sensitive.
• Further research is needed to optimize PABM for athletic and nutritional applications.
