Effects of rehydration and nutritional recovery strategies after rapid weight loss on body mass recovery, hydration status, and performance in combat sports athletes: a 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
Background: Rapid Weight Loss (RWL) is common in weight-category combat sports, but the extent to which post-weigh-in feeding and rehydration restore body mass, hydration, and exercise performance remains uncertain. Objective: To quantify post-weigh-in body-mass regain and hydration status and to evaluate nutritional and rehydration strategies and subsequent exercise performance in combat-sport athletes. Methods: This review followed PRISMA 2020 and was registered in PROSPERO (CRD420261438676). PubMed, SPORTDiscus, Embase, and Web of Science were searched from inception to July 2026. English-language human studies involving RWL or weight making followed by recovery were eligible. Comparable continuous outcomes were pooled using random-effects models with modified Hartung-Knapp confidence intervals; heterogeneous strategy and performance outcomes were synthesized using evidence maps and effect-direction methods. Results: Forty studies were included in the main post-weigh-in recovery review. Pooled post-weigh-in body-mass regain was 6.23% of body mass (95% CI 3.74-8.71; Conclusion: Combat-sport athletes commonly regain substantial body mass after weigh-in, but body-mass regain should not be interpreted as complete rehydration or restored performance readiness. Current strategy-specific evidence is insufficient to identify a superior recovery protocol; standardized, adequately powered trials using multidimensional recovery outcomes are needed.
