The Exploration for the Relationship between Intestinal Flora and Physical Quality of the High-levelAthletes inAgricultural Universities
摘要
Abstract
For studying Agricultural universities’ high-level athletes intestinal flora fauna and physical relationship, solving the problem of gastrointestinal motility syndrome, improving the competitive level of athletes, we collect the fresh fecal samples of athletes from Shandong Agricultural University to isolate and identify the normal flora of the gastrointestinal tract. Lactobacillus, the normal flora dominant bacteria are conducted for 16SrRNA analysis and developed into oral liquid. After safety testing, it used to subjects, taking for 10 days, once a day before lunch, observe the relationship between the changes in athletes’ gastrointestinal flora and their physical quality. The results show that the dominant flora in athletes’ intestinal are Lactobacillus, Bifidobacterium, Peptococcus and Enterococcus, and the average of normal intestinal flora between heterosexual has a significant difference(P<0.05), but the difference between different regions of the same sex is not significant(P>0.05).The four strains of Lactobacillus acidophilus、Lactobacillus crispatus、Lactobacillus rhamnosus and Lactobacillus salivarius are conducted for 16SrRNA detection and analysis and compare with the sequence in Genbank: the homology are 99.2 %, 99.1 %, 99.8% and 98.9%. After taking probiotics, the gastrointestinal function, exercise endurance and the ability to anti-cold of tested athletes are all enhanced significantly. Besides, the resistance to fatigue is enhanced for 0.7-1.1 h. Those show that the intestinal flora fauna of athletes and their physical quality have a close relation. Insisting on taking probiotics can improve the athletes’ athletic ability significantly and solve the problem of gastrointestinal motility syndrome. Besides, it can provide a theoretical basis for improving the level of athletes.关键词
