Endurance sport improves neuronal connections to muscle fibers

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.
