Although the title "World's Greatest Athlete " seems a natural fit for these two events, its traditional association with the decathlon/heptathlon officially began with Jim Thorpe . During the 1912 Olympics in Stockholm, Sweden, Thorpe won the gold medal in the Decathlon (among others). Thorpe notably also competed professionally in soccer , baseball , American Football , and basketball ; and competed collegiately in track and field , soccer , baseball , lacrosse , and did ballroom dancing . King Gustav V of Sweden , while awarding Thorpe the decathlon gold said: "You, sir, are the greatest athlete in the world." That title has become associated with the decathlon event ever since.
It is evident that the gut microbiota and factors that influence its composition and activity effect human metabolic, immunological and developmental processes. We previously reported that extreme physical activity with associated dietary adaptations, such as that pursued by professional athletes, is associated with changes in faecal microbial diversity and composition relative to that of individuals with a more sedentary lifestyle. Here we address the impact of these factors on the functionality/metabolic activity of the microbiota which reveals even greater separation between exercise and a more sedentary state.
