Endurance sport does not only change the condition and
fitness of muscles but also simultaneously improves the neuronal connections to
the muscle fibers based on a muscle-induced feedback. This link has been
discovered by a research group at the Biozentrum of the University of Basel.
The group was also able to induce the same effect through raising the protein
concentration of PGC1α in the muscle. Their findings, which are also
interesting in regard to muscle and nerve disorders such as muscle wasting and
ALS, have been published in the current issue of the journal Nature
Communications.
