[Purpose] Functional beverages are a protective or enhancing factor influencing not only public health but also athletic performance. The purpose of this study was to highlight the new conditioning beverage of the Lactobacillus pentosus strain b240 (B240) with electrolytes or proteins, which strengthens immune functions to improve the quality of life. [Methods] ISeveral related studies systematically reviews three main issues associated with conditioning beverages: (a) utilization and availability of the functional beverage; (b) significance of B240 in immune strengthening; and (c) availability and application of conditioning drinks in the daily life and sports field. [Results] Intake of B240 led to greater enhancements, including blood T-helper, NK cell, IgA and IgG level in conjunction with strengthen immune functions. These results speculated that the practical application of B240 contained beverages on physiological health and performance. [Conclusion] BODYMAINTÉ, this novel conditioning beverage is expected biological utility responsible for improved sports performance as a functional drink and has potential health-related implications.

[Purpose] Functional beverages are intended to support those who want to maintain optimal physical condition and improve their quality of life through the enhancement of heart health, immunity, and digestion. The purpose of this study was to investigate the performance of top-level athletes consuming immune-strengthening conditioning nutritional drinks. [Methods] A total of 107 top-level athletes (baseball (56 players), pro volleyball (17), athletics (16), cycling (8), golf (6), and fencing (6)) participated in the experiment. They consumed an immune-enhancing functional beverage once a day for 8 weeks and responded to a survey before, during, and after drinking the beverage. [Results] Three total aspect-based subfactors were drawn from 24 questions in the factor analysis: physical, satisfaction with mental stability, and activity in performance. The physical, mental stability and performance changes of athletes significantly increased in period 2 (4 weeks after intake) and period 3 (after 8 weeks of intake). [Conclusion] We evaluated the efficacy of a new conditioned beverage containing Lactobacillus B240 and protein in improving the performance and physiological utility of top athletes. This functional drink may gain popularity among those seeking health benefits and improved exercise performance.

From a genomic library of Lactobacillus reuteri ATCC 55739, one clone, NE347, carrying a pyrH gene encoding UMP kinase, was identified. pNE347 carried a 1.88 kb EcoRI fragment and the pyrH was located in the middle of the insert. pyrH ORF was 723 bp in size and capable of encoding UMP kinase composed of 240 amino acid residues. tsf encoding an elongation factor-Ts and frr encoding a ribosomal recycling factor were present upstream and downstream of pyrH, respectively. When introduced into E. coli KUR1244, a pyrH-negative strain, pNE347 restored the ability to grow at $42^{\circ}C$, indicating that pyrH from L. reuteri synthesized functional UMP kinase in E. coli. Northern blot experiment showed that pyrH and frr were cotranscribed as a 1.4 kb single transcript. pyrH was overexpressed in E. coli by using a pET26b(+) vector, and a major 25 kDa protein band appeared on SDS-polyacrylamide gel.
