Peer-Reviewed Research: Insights on Mitochondrial Function, ATP Production, and Qigong
The journal article by Zhang, Su, and Li (2023) offers a comprehensive mechanistic framework connecting Qigong exercise with improved oxygen metabolism, mitochondrial function, and ATP production, framed within the context of modulating hypoxia and restoring physiological balance. This review focuses on the mitochondrial and metabolic mechanisms proposed in the article, specifically how Qigong influences ATP synthesis via oxidative phosphorylation (OXPHOS), modulates the lactate/pyruvate axis, and assists in acid-base balance at a cellular level.
1. Energy Metabolism and Hypoxia: The Foundation for Qigong’s Role
The authors begin by explaining that ATP—the primary unit of cellular energy—is generated predominantly via oxidative phosphorylation in the mitochondria under normoxic conditions. This process yields 30–32 ATP molecules per glucose, in contrast to the glycolytic pathway under hypoxic conditions, which yields only 2 ATP per glucose molecule.
When tissues face hypoxic stress, such as during intense exercise or pathological conditions like ischemia, mitochondrial respiration becomes impaired. Consequently, cells shift to glycolysis for rapid but inefficient ATP production. This transition leads to the accumulation of lactate and hydrogen ions (H⁺), which create an acidic microenvironment—a condition implicated in muscle fatigue, inflammation, and even tumor progression.
Zhang et al. emphasize that this metabolic shift, while adaptive in the short term, leads to cellular stress and a depletion of glycogen stores. Importantly, the accumulation of lactate and intracellular acidosis serves as both a protective mechanism (by signaling fatigue to prevent damage) and a pathological contributor to tissue dysfunction. The buildup of lactate also inhibits mitochondrial ATP production due to disrupted redox balance and mitochondrial membrane potential.
2. Qigong’s Role in Mitochondrial Function and Oxygen Economy
Qigong exercise, which incorporates slow movement, focused breathing, and meditative awareness, appears to mitigate these stressors by improving the body’s oxygen economy and promoting efficient energy metabolism. The article identifies three primary mechanisms by which Qigong modulates oxygen supply and mitochondrial function:
a. Reducing Oxygen Consumption:
Through inducing a deeply relaxed parasympathetic state and reducing cognitive and muscular effort, Qigong significantly lowers the oxygen demand of high-consumption tissues like the brain and skeletal muscles. This lowered demand decreases the reliance on anaerobic glycolysis, thereby preventing the switch to lactate-producing pathways and maintaining oxidative phosphorylation.
b. Increasing Oxygen Supply:
Qigong enhances pulmonary oxygen exchange through deep diaphragmatic breathing techniques. This results in elevated arterial oxygen saturation, increased hemoglobin oxygen content, and greater oxygen availability to mitochondria for aerobic respiration.
c. Facilitating Lactate Clearance and Utilization:
The authors describe how Qigong stimulates systemic microcirculation, improving the removal and redistribution of lactate. Lactate, once considered a mere metabolic byproduct, is now recognized as a substrate for mitochondrial respiration and a signaling molecule that influences gene expression. Qigong thereby supports the reintegration of lactate into the energy cycle through the lactate–pyruvate–acetyl-CoA pathway, enabling the restoration of mitochondrial ATP output.
3. Oxidative Phosphorylation and Mitochondrial Regulation via Qigong
A core contribution of the article is its explanation of Qigong’s role in regulating mitochondrial oxidative phosphorylation (OXPHOS). OXPHOS, involving the electron transport chain (ETC), is sensitive to oxygen availability and subject to fine control by various transcriptional and post-translational regulators.
Zhang et al. argue that Qigong indirectly stabilizes mitochondrial OXPHOS by:
Increasing oxygen availability to Complexes I–V of the ETC, enabling full oxidation of pyruvate.
Limiting the accumulation of reactive oxygen species (ROS) by preventing hypoxia-induced metabolic stress.
Modulating protein acetylation and lactylation in mitochondria and nuclei, which are reversible modifications affecting enzyme activity in the OXPHOS system.
These adaptive mechanisms suggest that Qigong can enhance ATP production by optimizing the conditions for mitochondrial respiration while preventing hypoxia-induced mitochondrial dysfunction.
4. Epigenetic Feedback and Energy Homeostasis
An innovative section of the article explores how hypoxia and lactate accumulation trigger epigenetic responses through histone lactylation and acetylation. During hypoxia, lactate can be used as a donor for protein modifications that temporarily suppress gene expression and mitochondrial enzyme activity—an adaptive mechanism to reduce oxygen consumption.
Qigong may facilitate the reversal of these modifications through:
Enhancing oxygen delivery, thus restoring redox balance.
Promoting the activity of deacetylase enzymes such as SIRT proteins that remove lactylation and acetylation marks.
Supporting a shift from emergency metabolism (glycolysis) to homeostatic oxidative phosphorylation.
This epigenetic dimension links Qigong to the regulation of metabolic gene networks and mitochondrial biogenesis, potentially contributing to improved energy resilience and metabolic health over time.
5. Qigong, Mitochondria, and Lactate as a Signaling Molecule
Another key insight is the dual role of lactate—not only as a fuel substrate but also as a signaling molecule influencing brain function, inflammation, and tissue repair. Qigong may optimize lactate’s function by:
Preventing its excessive accumulation (which leads to acidosis).
Facilitating its transport to the brain and other organs where it plays neuroprotective and cognitive-enhancing roles.
Modulating the expression of receptors like HCAR1 that mediate lactate’s signaling effects on neuroplasticity and angiogenesis.
This metabolic re-routing suggests that Qigong does not merely “burn off” excess lactate but utilizes it constructively in cross-organ metabolic coupling—particularly between muscles and the brain.
6. Therapeutic Implications and Integration with Preemptive Medicine
The article situates Qigong within the emerging framework of Preemptive Health & Medicine (PHM). By targeting early disruptions in oxygen metabolism and mitochondrial function, Qigong may act as a non-invasive, self-regulating tool to prevent or ameliorate chronic diseases characterized by energy imbalance, including:
Cardiovascular disease
Neurodegenerative conditions
Cancer (especially in hypoxic tumor microenvironments)
Mood and anxiety disorders
Qigong’s potential to restore mitochondrial energy metabolism and ATP production in these contexts highlights its value as a therapeutic platform in both preventive and rehabilitative medicine.
Conclusion
Zhang, Su, and Li (2023) provide a compelling mechanistic model connecting Qigong to mitochondrial function and ATP production. The article bridges Eastern meditative movement and Western cellular bioenergetics, offering a multidimensional view of how slow, mindful exercise supports cellular health.
Key mechanisms include:
Enhanced oxygen supply and reduced oxygen demand.
Restoration of oxidative phosphorylation and ATP synthesis in mitochondria.
Clearance and re-utilization of lactate as an energy and signaling molecule.
Epigenetic modulation of energy metabolism through lactylation and acetylation.
Systemic improvements in microcirculation and acid-base balance.
These insights underscore Qigong’s potential as a powerful tool for modulating cellular energy dynamics, reducing oxidative stress, and promoting metabolic harmony in both health and disease.
