Effects of Sodium Bicarbonate Supplementation on Performance and Gastrointestinal Symptoms During a High-Intensity Training Session in Elite Rugby Players: A Double-Blind Randomized Controlled Trial.
Article in Sports (Basel, Switzerland), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07017582 (Bicarbonate and Rugby), which is not on this map. Cited by 1 paper, 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.

Abstract
backgroundSodium bicarbonate (SB) supplementation can enhance performance in short, high-intensity movements. However, its effectiveness in team sports such as rugby remains insufficiently explored.
methodsIn this double-blind, parallel, controlled trial, 17 male professional rugby players ingested SB (0.3 g/kg) or a placebo 90 min before a high-intensity, rugby-specific training session monitored via GPS. The training session was conducted under real-world conditions to enhance ecological validity. Physical performance (countermovement jump, CMJ), fatigue markers (capillary lactate and ratings of perceived exertion, RPE), and gastrointestinal (GI) symptoms were assessed pre- and post-exercise.
resultsNo significant pre-post changes were observed in CMJ performance in either group. Lactate concentrations increased from pre- to post-exercise in both groups (both
conclusionsAcute SB ingestion at 0.3 g/kg did not result in detectable improvements in performance or fatigue markers during rugby-specific high-intensity training and was associated with a greater incidence of GI discomfort; however, the study was underpowered to detect small between-group differences. This study was registered on 23 May 2025 on ClinicalTrials.gov (NCT07017582).
