A diet, individually customized to the needs of sportsmen and sportswomen prepares them better for competition and achievement of better sports results. However, disorders of the gastrointestinal tract and frequently recurrent upper respiratory tract infections pose a common problem observed among athletes of disciplines such as triathlon, cycling and marathon. Diarrhea, splashing in the intestines or gastrointestinal bleeding make it difficult to start and win in the race. Recently researchers have paid special attention to the therapeutic effect of probiotic strains on the human body. Various probiotic strains may have a beneficial effect on elimination of disorders mentioned above among athletes of these disciplines. Still, researchers continue looking for answers to the question how a specific probiotic strain is able to reduce the risk of the gastrointestinal tract and the respiratory system disorders appearing during training or competition. Attention is also drawn to the possible impact of probiotics on the physical capacity athletes and their athletic performance. Probiotic strains properly applied may have a positive influence on the athletes’ bodies, but still randomized controlled trials are required to prove this thesis.
