VO2 Max Nutrition

Physiology

Dietary strategies—particularly dietary nitrate from beetroot juice—that enhance maximal oxygen uptake by improving mitochondrial efficiency and reducing the oxygen cost of submaximal exercise.

Related Technique
Beetroot Juice

A vibrant red vegetable extract that is exceptionally high in inorganic nitrates (NO3-). Inside the body, these nitrates are reduced to nitric oxide (NO), a powerful vasodilator that relaxes blood vessels, increases oxygen delivery to active skeletal muscles, and enhances mitochondrial efficiency during aerobic and anaerobic workloads.

More Physiology Terms

Anabolism

The metabolic state of building or repairing muscle tissue. Triggered by adequate protein intake, resistance training, and low systemic stress.

Autophagy

A natural cellular self-clearing process where the body breaks down and recycles damaged proteins and cellular components. Promoted by intermittent fasting.

Catabolism

The metabolic state of breaking down complex molecules into simpler ones, often resulting in muscle tissue loss during extreme calorie deficits or chronic stress.

Glycogen

The storage form of glucose in muscle and liver tissue. Crucial for supplying explosive energy during high-intensity athletic performance.

Insulin Sensitivity

How responsive cells are to insulin. High sensitivity allows glucose to enter cells efficiently, reducing fat storage and improving muscle fueling.

Ketosis

A metabolic state where the liver converts fats into ketones to use as energy when glycogen stores are depleted.
