Endocrine Crosstalk Between Skeletal Muscle and the Brain

Area of Science:

• Exercise physiology
• Neuroscience
• Endocrinology

Background:

• Skeletal muscle regulates energy and exercise adaptations in organs like the brain.
• Muscle communicates via secreted myokines and metabolite exchange.
• This communication impacts brain functions and overall health.

Purpose of the Study:

• To review how exercise and the muscle secretome influence brain functions.
• To explore mechanisms of muscle-brain crosstalk.
• To highlight physical activity's role in preventing brain disorders.

Main Methods:

• Literature review of current research on muscle-brain interactions.
• Analysis of studies on myokines and metabolites.
• Synthesis of findings on exercise's impact on brain health.

Main Results:

• Exercise and myokines improve brain vascularization, neuroplasticity, memory, sleep, and mood.
• Metabolite exchange between muscle and brain is a key mediator.
• Mechanisms of muscle-brain communication require further elucidation.

Conclusions:

• Physical activity is a potent strategy for enhancing brain function.
• Exercise and myokines offer therapeutic potential for neurological and mood disorders.
• Further research into muscle-brain crosstalk is warranted.
