Effectiveness of beetroot juice on aerobic and anaerobic exercise performance: systematic review and meta-analysis.
Synthesis in Frontiers in nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: Beetroot juice (BJ), a natural source of dietary nitrate, has been widely studied for its potential ergogenic effects; however, evidence integrating both aerobic and anaerobic performance outcomes remains limited. This meta-analysis evaluated the effects of BJ supplementation on maximal oxygen uptake (VO₂max), high-intensity interval sprint (HIS) performance, and mean power output (MPO). Methods: A comprehensive literature search was conducted across six databases (Wiley Online Library, Web of Science, Scopus, SpringerLink, PubMed, and ScienceDirect), supplemented by manual searches of Google Scholar. Meta-analysis, subgroup analysis, meta-regression analysis, publication bias assessment, and sensitivity analyses were performed using Stata 17. Results: Thirty-three studies were included in the review. BJ supplementation significantly improved HIS (SMD = 0.38, 95% CI 0.17 to 0.59, Conclusion: As a natural ergogenic aid, beetroot juice effectively improves both aerobic and anaerobic exercise performance and can be recommended.
