Key Concepts

• Interconnectedness of Muscle and Bone: The musculoskeletal system, composed primarily of muscle and bone, plays a crucial role in movement and metabolic health. These tissues are anatomically and physiologically connected, impacting each other's metabolism and overall health.
• Endocrine Roles: Beyond their biomechanical functions, muscle, bone, and adipose tissue (AT) secrete cytokines that act as signaling molecules, influencing the metabolism of each other and the whole body.

Effects of Aging and Inactivity:

• The article emphasizes that aging, physical inactivity, and a chronic energy surplus (consuming more calories than expended) contribute to a decline in muscle and bone mass and function, leading to conditions like:
