Probiotic Strain Found to Help Improve Aerobic Endurance and Reduce Body Fat
Lactobacillus plantarum is a probiotic that can be found in fermented foods. Previous studies have found that it may help regulate inflammation-related diseases and protect the respiratory tract from viral infection. According to a new study, it may also help improve aerobic endurance and reduce body fat.
Fifty-four adults without professional athletic training participated in the study. They were assigned to one of three interventions for 6 weeks: a high dose of Lactobacillus plantarum TWK10 (9 X 1010 CFU/day), a low dose of Lactobacillus plantarum TWK10 (3 X 1010 CFU/day), or a placebo. Maximal oxygen consumption and aerobic endurance were measured using a treadmill at baseline and at the end of the study period. Body composition measurements were taken at baseline and at the end of the study period.
The researchers found that participants in both Lactobacillus plantarum TWK10 groups had a significant increase in time to exhaustion. Aerobic endurance was increased by 20.7% in the low dose group and by 40.2% in the high dose group. Participants in the supplement groups also had a fat mass decrease and increase in muscle mass.
In addition, the supplement group participants had lower lactate production than the placebo group, and significantly higher serum glucose levels during exercise.
The study was conducted by researchers from National Taiwan Sport University. It was published online ahead of print on November 19, 2019 in the journal Nutrients.
