Abstract

Purpose

The aim of this study was to evaluate the use of probiotic products in Hungary, to explore consumers' knowledge of probiotics, and to gain information about the main characteristics of current usage.

Materials and Methods

The research used a self-developed explorative questionnaire to obtain the necessary information. The data collected was further analysed with IBM SPSS 25.0 and Microsoft Office Excel.

Results

Nearly three-quarters of respondents (73.9%) have used probiotics in their life. Those who have already used these products, mostly heard about them from doctors (62.8%) and friends/relatives (40.5%), while among non-users the main sources of information were web pages (46.8%) and commercials (45.2%).

Conclusions

We found several differences between users and non-users in terms of probiotics awareness. Consequently, healthcare providers may play an important role in the process of careful product choice and proper usage.

Abstract

Purpose

Intensive exercise significantly lowers the pH of muscle and blood; beta-alanine supplementation can increase carnosine levels, the absence of which leads to an early acidosis and fatigue. The aim of our work is to investigate the effect of a single dose of beta-alanine supplementation on well-trained rowing athletes.

Materials/Methods

The spiroergometric parameters of the participants (n = 28) were examined a total of four times (T1,T2,T3,T4). After measurement (T3), participants received a beta-alanine supplementation at a dose of 50 mg/kg−1 body weight. We compared the results of the four measurements as well as the blood lactate values obtained from the fingertip before and after the tests.

Results

The different load physiological parameters and the lactate values measured after the tests did not show any significant difference. The mean lactate value prior to test (T4) was 1.8 (mmol*L−1), which is significantly higher than the mean-value of the two previous studies: T1 = 1.6 (mmol*L−1); (P = 0.00), T3 = 1.55 (mmol*L−1); (P = 0.04).

Conclusions

The higher lactate value measured before test (T4) was probably due to the longer time to return to the baseline values after the series load. In conclusion, a single dose of beta-alanine supplementation has no effect on performance. In order to elicit the ergogenic effect of beta-alanine, the use of short, intermittent diet therapy intervention is not recommended.
