Exercise Alleviates Cardiovascular Diseases by Improving Mitochondrial Homeostasis

Area of Science:

• Cardiovascular Science
• Mitochondrial Biology
• Exercise Physiology

Background:

• Cardiovascular diseases (CVDs) are a major health concern.
• The precise mechanisms linking exercise to CVD prevention are not fully understood.
• Mitochondrial dysfunction is increasingly recognized in CVD pathology.

Purpose of the Study:

• To review the benefits of physical exercise on cardiovascular diseases (CVDs).
• To elucidate the role of mitochondrial homeostasis in exercise-induced cardioprotection.
• To explore molecular mechanisms underlying exercise's impact on mitochondria in CVDs.

Main Methods:

• Comprehensive literature review of studies on exercise, CVDs, and mitochondria.
• Analysis of molecular and cellular mechanisms involved in mitochondrial function.
• Synthesis of current knowledge on exercise's effects on mitochondrial biogenesis, dynamics, and quality control.

Main Results:

• Exercise training significantly improves mitochondrial homeostasis, counteracting CVD-related disruptions.
• Key benefits include enhanced mitochondrial biogenesis, fusion, and mitophagy.
• Exercise mitigates detrimental changes in mitochondrial morphology and function.

Conclusions:

• Disruption of mitochondrial homeostasis is a critical factor in cardiovascular disease development.
• Exercise effectively restores mitochondrial homeostasis, offering protective effects against CVDs.
• Understanding these mechanisms provides a basis for novel exercise-based therapeutic strategies for CVDs.
