Monitoring and Assessment of Jump Performance, Workload, and Injury Risk in the Romanian Under-16 Women's National Volleyball Team.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
backgroundVolleyball requires frequent jumping, landing, and overhead movements, predisposing athletes to acute and overuse injuries. Monitoring workload and neuromuscular performance is important for optimizing performance and preventing injuries in youth athletes. MATERIALS AND
methodsA retrospective observational analysis was performed using prospectively collected data from a training camp of the Romanian Under-16 (U16) women's national volleyball team. Twenty athletes were included in the study (mean age: 14.25 ± 0.72 years). Data collection consisted of demographic information, injury history, and perceived exertion, assessed with the modified Borg Category-Ratio 10 (CR10) scale. The training workload (TWL) was derived from session ratings of perceived exertion, while the acute-to-chronic workload ratio (ACWR) was calculated across the four weeks preceding the index week. In addition, neuromuscular performance was evaluated using the OptoJump Next system (Microgate S.r.l., Bolzano, Italy). Athletes completed three standardized tests at both the beginning and end of the camp.
resultsWeekly TWL was similar between groups (injured: 3,723.4; non-injured: 3,664.4). However, only 37.5% of injured athletes remained within the ACWR "safe zone" (0.8-1.3) compared to 75.0% of non-injured athletes. OptoJump assessments revealed no substantial performance differences, and by camp exit, previously injured athletes achieved comparable jump height, reactive strength index (RSI), and relative power to their peers.
conclusionsAlthough workloads were broadly similar, injured athletes demonstrated greater fluctuations in ACWR, indicating increased reinjury risk. Effective and personalized rehabilitation allows recovery of neuromuscular performance, but careful workload management remains essential. Integrating load monitoring with neuromuscular assessment may improve injury prevention strategies in youth volleyball players.
