Repeated-Sprint Training in Hypoxia Induced by Voluntary Hypoventilation at Low Lung Volume: A Meta-analysis.
Synthesis in Sports medicine - open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled it.
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
backgroundRepeated-sprint training in hypoxia (RSH) induced through voluntary hypoventilation at low lung volume (RSH-VHL) may represent a low-cost alternative to systemic hypoxia. This meta-analysis aimed to systematically assess the effects of RSH-VHL training interventions on sea-level physical performance compared to similar repeated-sprint training with normal breathing (RSN).
methodsThe PubMed/MEDLINE, SportDiscus
resultsFrom the 776 studies identified through systematic search, 10 studies including a total of 199 individuals (157 males and 42 females) were eligible for meta-analysis. While no effect was observed for RSA
conclusionRepeated-sprint training in hypoxia induced by voluntary hypoventilation at low lung volume provides putative gains in fatigue resistance during repeated sprints. Higher maximal blood lactate concentration suggests greater glycolytic contribution during RSH-VHL compared to RSN. Mechanisms underlying these effects are currently unclear and have yet to be identified.
