Differences in gut microbiota profile between women with active lifestyle and sedentary women

La actividad física en dosis bajas pero de forma continua puede incrementar la abundancia de bacterias que promueven cambios positivos en la salud (Bifidobacterium spp, R. hominis, A. muciniphila and F. prausnitzii). A pesar de no encontrar aumentos en la riqueza de la microbiota, encontramos una asociación inversa entre parámetros relacionados con el sedentarismo y la riqueza de la microbiota (número especies y los índices de Shannon y Simpson).

The results presented here together with previous findings show that physical activity modulates the microbiota profile. Our results indicate that physical activity performed at low doses but continuously can increase the abundance of health-promoting bacteria (Bifidobacterium spp, R. hominis, A. muciniphila and F. prausnitzii) in the microbiota. Although we failed to findan increase in microbiota richness, we found an inverse association between sedentary parameters and microbiota richness (number of species, and Shannon and Simpson indices), which might indicate that perhaps not only is the dose and mode of exercise important, but also the pattern of exercise, such as breaks in sedentary time, avoiding long periods of inactivity in daily life, to induce changes in gut microbiota.
