Epigenetic adaptation to regular exercise in humans.

Area of Science:

• Exercise physiology
• Epigenetics
• Molecular biology

Background:

• Regular exercise is linked to reduced risks of cardiovascular disease, cancer, and type 2 diabetes.
• Sedentary lifestyles are increasing globally, despite known exercise benefits.
• Molecular mechanisms of exercise benefits, including gene expression changes, have been studied for decades.

Purpose of the Study:

• To review recent advancements in understanding the relationship between regular exercise and epigenetics.
• To highlight the novel finding that exercise can modify genome-wide DNA methylation patterns in humans.

Main Methods:

• This review synthesizes findings from recent scientific literature.
• Focuses on studies investigating exercise interventions and epigenetic modifications, specifically DNA methylation.

Main Results:

• Exercise is established to alter gene expression across multiple tissues.
• Emerging evidence indicates regular exercise can induce genome-wide DNA methylation changes in humans.

Conclusions:

• Exercise-induced epigenetic modifications, particularly DNA methylation, represent a key molecular mechanism underlying its health benefits.
• Further research into exercise and epigenetics can inform lifestyle interventions for disease prevention.
