What role does Stuhlprobe play in Sport?

Stool sample (microbiome) analysis in sports is an emerging field with limited evidence. The gut microbiome may influence inflammation, nutrient absorption, and immune function, potentially affecting recovery and performance. Studies show differences between endurance and strength athletes, but no standardized protocols or strong causal links exist. Personalized diet changes based solely on a stool test are speculative. MyBody-X may offer such tests, but clinical validity for athletes is not established. The role is more about general health optimization than specific performance gains. Be cautious of overblown marketing claims. Research is still in early stages.
