More and more studies show the great importance of our microbiota and its positive impact on our well-being. The scientific world has made major steps forward in medicine unraveling some of the mysteries of the gut-brain axis, and highlighting the existing link with many diseases, particularly neurocognitive disorders such as Alzheimer’s or Parkinson’s disease. Recently, a study demonstrated that intestinal bacteria play a proven role in maintaining the muscle strength in elderly people and introduced the concept of a gut-muscle axis.

The discovery of this new bidirectional communication between the gut bacteria and our body can help to understand the changes in the microbiota composition during ageing, and brings new possibilities for a healthier ageing. At the dawn of 2020, doctors and patients deliberately choose to replace some drug treatments with sport activity in order to increase the body strength and energy, and overcome the concept of ​​fragility in elderly patients.

In summary, these evidences suggest a role for the gut flora on the maintenance of muscle strength and hypothesize that bacteria, which has been underestimated for so long, may offer new perspectives to improve the ageing process.
