New study finds gut instability may hinder performance
Researchers have studied the performance andgut health of a group of well trained runners to study the effects of both high protein and high carbohydrate diets. It turned out that in those who followed a diet high in protein, the stability of the intestinal microbiome was disturbed. This was also accompanied by a 23.3% decrease in time trial performance. Those participants whose gut microbiome was more stable performed better during the trials.
In contrast, those who followed a high carbohydrate diet showed a 6.5% improvement in time trial performance.
