Sexually dimorphic hepatic mitochondrial adaptations to exercise: a mini-review

Area of Science:

• Physiology
• Metabolism
• Mitochondrial Biology

Background:

• Exercise induces physiological stress, increasing energy demand primarily in skeletal muscle.
• The liver plays a crucial role in maintaining metabolic homeostasis by supplying substrates during exercise.
• Hepatic mitochondrial function is vital for ATP production, supporting metabolic flexibility.

Purpose of the Study:

• To review hepatic mitochondrial adaptations in response to exercise.
• To highlight the role of sexual dimorphism in these exercise-induced hepatic responses.

Main Methods:

• Literature review of studies investigating exercise, liver metabolism, and mitochondria.
• Focus on research examining sex-based differences in hepatic adaptations.

Main Results:

• Exercise necessitates hepatic mitochondrial ATP production to meet systemic energy demands.
• Liver mitochondrial health and dynamic regulation are essential for metabolic flexibility.
• Observed hepatic adaptations to exercise exhibit notable sex-dependent characteristics.

Conclusions:

• The liver's mitochondrial responses to exercise are critical for metabolic homeostasis.
• Sexual dimorphism significantly influences hepatic mitochondrial adaptations to exercise, warranting further investigation.
