Beets are one of the best-studied vegetables in sports nutrition. Rich in nitrates, which dilate blood vessels and improve endurance.

Here are the main beets for sports benefits in an athlete's nutrition:
The best ways to prepare beets for sports, while preserving maximum nutritional value:
Before competition (2-3 h) - for the nitrate effect. After training - for recovery.
Best alternatives beets for sports:
Spinach (also contains nitrates), celery, carrots, radishes
Average serving — 1–2 boiled beets (150–250 g). Nitrates in beets are a natural part of the plant; when consumed regularly, the body converts nitrates into nitric oxide, which participates in the regulation of vascular tone.
Choose firm beets with a smooth surface and fresh leaf remnants. Store in the refrigerator; cut off any remaining leaves — they draw moisture from the root. Do not peel before boiling so they lose less color.
Beets stand out for their nitrates — in the body they are converted into nitrites, and these participate in the formation of nitric oxide. Nitric oxide is a signaling molecule involved in regulating the tone of the blood vessel wall, which is why beets are often associated with endurance sports. The nitrate content depends greatly on the variety, soil, and storage, so it is better not to expect specific numbers.
Are beets suitable only for endurance sports? No, they are also suitable as an ordinary vegetable — the effect of nitrates is just one of many reasons to eat them.
Is juice better than boiled beets? Juice is more concentrated but has no fiber; the most practical option is to eat the vegetable itself.
Does the color of beets indicate quality? Not always — color is determined by pigments, not nutritional value.
