Eight-Week Shoulder Flexibility Program Improves Serve Accuracy and Select ROM in Youth Volleyball: A Randomized Controlled Trial.
Trial report in Journal of musculoskeletal & neuronal interactions, 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
objectiveThis study investigated the effects of an eight-week shoulder flexibility exercise program on shoulder range of motion (ROM) and serve accuracy in youth volleyball players.
methodsThirty-two adolescent players (12-13 years) were randomly assigned to an experimental group (EG, n=16) and a control group (CG, n=16). The EG performed structured flexibility exercises twice weekly in addition to regular training, while the CG continued routine volleyball practice only. Shoulder ROM was assessed with a goniometer, and serve accuracy was evaluated using a standardized scoring protocol (maximum 48 points).
resultsSignificant improvements were observed over time in both groups for most ROM variables (p < 0.001). However, significant group differences emerged for shoulder external rotation (F
conclusionThe eight-week flexibility program significantly enhanced serve accuracy and select shoulder ROM parameters in youth volleyball players. Incorporating structured flexibility exercises into training routines may improve technical performance and support shoulder function development during early adolescence.
