Exercise as Vascular Medicine: Can Exercise Combat Negative Health Behaviors From Causing Endothelial Dysfunction?

Area of Science:

• Cardiovascular Science
• Vascular Biology
• Exercise Physiology

Background:

• Endothelial function regulates vascular health by controlling nitric oxide release, redox balance, and cell proliferation.
• Impaired endothelial function, or endothelial dysfunction, is a significant risk factor for cardiovascular disease (CVD), the leading global cause of mortality.
• Aging, poor diet, sedentary behavior, and inadequate sleep negatively impact endothelial function and vascular aging.

Purpose of the Study:

• To review the critical role of endothelial function in maintaining cardiovascular health.
• To identify key risk factors and underlying mechanisms contributing to endothelial dysfunction.
• To summarize the protective effects of exercise on endothelial function and discuss its mechanisms.

Main Methods:

• This review synthesizes current literature on endothelial function, dysfunction, and the impact of exercise.
• It examines physiological mechanisms linking health behaviors to vascular aging.
• The review identifies knowledge gaps and proposes future research directions.

Main Results:

• Endothelial dysfunction is a central factor in the development of cardiovascular disease.
• Negative health behaviors accelerate vascular aging and impair endothelial function.
• Exercise demonstrates significant protective effects against endothelial dysfunction through various mechanisms.

Conclusions:

• Maintaining endothelial health is crucial for preventing cardiovascular disease.
• Lifestyle modifications, particularly exercise, can mitigate risks associated with vascular aging.
• Further research is needed to fully elucidate exercise's protective mechanisms and optimize interventions.
