1 · What the graph read from 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.

2 · The registry

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

Introduction: The aim of this study was to investigate the impact of different plyometric jump training (PJT) loading strategies, using either weighted vests (WV) or elastic bands (EB), on the physical and physiological performance of young volleyball players. Methods: Thirty-two male volleyball players participated in the study and were randomly assigned to WV-PJT (n = 8), EB-PJT (n = 8), unloaded PJT (UL-PJT, n = 8), and a control group (CG, n = 8). The players in the WV and EB groups performed PJT with resistance equivalent to 10% of body mass, while the UL group engaged in PJT without any additional loads. Moreover, the players in the CG only performed regular volleyball practice. Countermovement vertical jump (CMVJ), 10-m sprint, T-test change of direction speed (T-CODS), reactive strength index (RSI), 1 repetition maximum of leg press (1RM Results: All training groups (i.e., WV-PJT, EB-PJT, and UL-PJT) showed significant improvements (p = 0.001) in physical and physiological performance outcomes, with effect sizes ranging from small to large over the training period. Both the WV-PJT and EB-PJT groups exhibited greater adaptive changes (p < 0.05) compared to the UL-PJT group after the intervention. For the 1RM Conclusion: Loaded PJT is an effective method for producing greater adaptations in volleyball players. Specifically, WV-PJT is more beneficial for strength gains, while EB-PJT is superior for improving RSI and anaerobic power output.
