Number of participants that the trial has enrolled 32
Results K-W test scores and distance achieved during the 6MWT (6MWD) improved in both groups. The relative abundance of intestinal Bacteroides only significantly increased in the AE group, particularly in subjects showing increases in the time spent in brisk walking. Overall, the increases in intestinal Bacteroides following the exercise intervention were associated with increases in 6MWD.

Baseline Characteristics Thirty-two sedentary women that were aged 65 years and older participated in a 12-week, non-randomized comparative trial.
Participant flow The subjects were allocated to two groups receiving different exercise interventions, trunk muscle training (TM), or aerobic exercise training (AE). AE included brisk walking, i.e., at an intensity of > 3 metabolic equivalents (METs).
Adverse events None
Outcome measures The composition of the intestinal microbiota in fecal samples was determined before and after the training period. We also assessed the daily physical activity using an accelerometer, trunk muscle strength by the modified Kraus-Weber (K-W) test, and cardiorespiratory fitness by a 6-min. walk test (6MWT).
