Selective recovery effects of short-term beetroot juice supplementation after exercise-induced muscle damage in trained female volleyball players.
Trial report in Journal of the International Society of Sports 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
backgroundBeetroot juice (BRJ) has been proposed as a nutritional aid for recovery from exercise-induced muscle damage (EIMD), but evidence in female team-sport athletes is limited. It also remains unclear whether any benefit extends across functional, pain-related, swelling, and strength outcomes.
methodsSeventeen female university volleyball players entered a randomized, double-blind, placebo-controlled crossover trial. Four did not complete the second period, so outcomes were analyzed with linear mixed models. After baseline testing, participants performed 200 loaded vertical jumps and consumed BRJ or placebo at 24, 48, and 72 h post-EIMD. Recovery outcomes were countermovement jump (CMJ) height, volleyball-specific agility time, pressure pain threshold, thigh circumference, visual analog scale soreness, and knee isokinetic measures. Holm-adjusted planned contrasts were used.
resultsCMJ height was the clearest BRJ-related functional finding. The treatment × time interaction showed a trend toward statistical significance (
conclusionsShort-term BRJ supplementation was associated with selective rather than generalized recovery benefits after EIMD in trained female volleyball players. The clearest findings were higher CMJ height and calf PPT under BRJ than PLA at 72 h, whereas the remaining outcomes showed no consistent treatment-related differences.
