At the level of gene expression, PGC-1α is sensitive to numerous signaling cascades, most pronounced of which is the cAMP signaling pathway

Although both exercises activate PGC-1α gene (peroxisome proliferator-activated receptor-gamma coactivator), the adaptation processes stimulated are not the same and depend on the type of exercise.

Proteins run the body: They turn processes on or off or speed them up or slow them down. The body has many different proteins, and the instructions to make them are written on sections of DNA, referred to as genes. Different genes code for different proteins, but different proteins can also come from the same gene. Called isoforms, these proteins are produced when only part of the gene’s code is read.

The PGC-1α protein turns on other genes...

While it is not immediately clear why the communication between the brain and muscle was different as a result of different types of exercise, it offers leads for new means of research into neuromechanical differences in muscle function, muscle performance, muscle stiffness and other areas.

A University of Kansas study shows that the communication between the brain and quadriceps muscles of people who take part in endurance training, such as running long distances, is different than those who regularly took part in resistance training and those who were sedentary. The findings may offer clues to the type of physical activity humans are most naturally suited to.

Assistant Prof Trent Herda and Postdoc student Michael Trevino conducted studies in which they measured muscle responses of 5 peo...
