Area of Science:

• Cardiovascular Physiology
• Exercise Science
• Mitochondrial Biology

Background:

• Ischemic heart disease is a major global health burden.
• Effective therapies are needed for patients recovering from ischemic cardiac events.
• High-intensity interval training (HIIT) demonstrates cardioprotective potential against ischemia-reperfusion injury.

Purpose of the Study:

• To review the beneficial effects of HIIT on cardiac mitochondrial function.
• To elucidate the mechanisms by which HIIT confers cardioprotection.
• To identify knowledge gaps regarding HIIT's role in mitochondrial adaptation to ischemic stress.

Main Methods:

• Synthesis of current scientific evidence from clinical studies and animal models.
• Focus on the impact of HIIT on cardiac mitochondria.
• Examination of signaling pathways activated by HIIT.

Main Results:

• HIIT attenuates cardiac damage from ischemia-reperfusion injury.
• HIIT modulates mitochondrial function, enhancing resilience.
• Specific mechanisms involve activation of protective signaling pathways.

Conclusions:

• HIIT offers significant cardioprotection by improving mitochondrial function and resilience.
• Further research is crucial to fully understand HIIT's mechanisms and optimize its therapeutic application.
• HIIT represents a promising non-pharmacological intervention for managing ischemic heart disease.
