From the discovery of myokines to exercise as medicine.

Skeletal muscle is an endocrine organ that produces and secretes hundreds of myokines, allowing for crosstalk between the muscle and other organs. The discovery of myokines has contributed to laying the groundwork for exercise as medicine. Exercise activates multiple signalling pathways of importance for health. However, for the individual and society to benefit from such exercise effects, a true translational perspective on exercise as medicine is needed, ranging from molecular and physiological events to political decisions with direct implications for clinical practice and public health.
