Lactobacillus salivarius Subspecies salicinius SA-03 is a New Probiotic Capable of Enhancing Exercise Performance and Decreasing Fatigue

摘要

Probiotics are increasingly being used as a nutritional supplement by athletes to improve exercise performance and reduce post-exercise fatigue. is a natural flora in the gastrointestinal tract of humans and animals. subspecies (SA-03) is an isolate from the 2008 Olympic women’s 48 kg weightlifting gold medalist’s gut microbiota. In this study, we investigated its beneficial effects on physical fitness. Male ICR mice were divided into four groups ( = 10 per group) and orally administered with SA-03 for 4 weeks at 0, 2.05 × 10 , 4.10 × 10 , or 1.03 × 10 CFU/kg/day. Results showed that 4 weeks of SA-03 supplementation significantly improved muscle strength and endurance performance, increased hepatic and muscular glycogen storage, and decreased lactate, blood urea nitrogen (BUN), ammonia, and creatine kinase (CK) levels after exercise. These observations suggest that SA-03 could be used as a nutritional supplement to enhance exercise performance and reduce.
