Hyperbaric Oxygen Therapy and lactic acid in athletes
In high performance sport, managing fatigue is everything. One of the most discussed contributors to fatigue is lactate accumulation (often referred to as 'lactic acid'), which rises during intense exercise and is associated with metabolic stress and reduced performance.
In recent years, Hyperbaric Oxygen Therapy has gained attention as a recovery tool. But does it actually help athletes clear lactate faster and recover more efficiently?
Let's break down the physiology, the evidence, and what it means in practice.
Understanding lactate and athletic fatigue
During high-intensity exercise, the body relies on anaerobic metabolism, leading to increased production of lactate. While lactate itself is not purely a 'waste product', elevated levels are associated with:
Reduced muscle PH (acidosis)
Impaired muscle contraction
Perceived fatigue and reduced performance
Efficient lactate clearance is therefore a key component of recovery between training sessions or competitions.
Mechanisms: Why Hyperbaric Oxygen Therapy could help clear lactate
The potential benefits of Hyperbaric Oxygen Therapy for lactate clearance are rooted in basic physiology.
Increased oxygen availability. Higher oxygen levels support the conversion of lactate back into usable energy.
Enhanced mitochondrial function. Improved oxygen delivery allows muscles to shift more quickly from anaerobic to aerobic metabolism.
Improved circulation and microvascular flow. Hyperbaric Oxygen Therapy may enhance capillary perfusion, helping transport lactate out of muscle tissue more efficiently.
The research
'The effects of low-pressure HBOT before and after maximal exercise on lactate concentration, heart rate recovery, and antioxidant capacity' 2018
10 health male college students
Performed a maximal exercise three times at intervals of at least 7 days
Lactate concentration, heart rate, and antioxidant capacity were measured before, post, and after recovery 30 minutes of maximal exercise.
The lactate concentration and heart rate of recovery 30 minutes was significantly lower in the low-pressure HBOT group after maximal exercise compared with the control group.
