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

objectivesThis randomized controlled trial compared the effects of velocity-based complex training (VBCT) and traditional complex training (TCT) on lower-limb maximal strength and explosive performance in male volleyball athletes during the competitive season.

methodsThirty athletes were randomly assigned to VBCT (n = 10), TCT (n = 10), or a control group (CON, n = 10). The VBCT and TCT groups trained twice weekly for eight weeks. Pre- and post-intervention assessments included 1RM squat, countermovement jump (CMJ), squat jump (SJ), eccentric utilization rate (EUR), and standing long jump (SLJ).

resultsBoth VBCT and TCT improved 1RM squat, CMJ, SJ, and SLJ, whereas only VBCT improved EUR (p < 0.01). Post-intervention, VBCT demonstrated significantly greater improvements than TCT in CMJ (VBCT: η² = 0.65; TCT: η² = 0.41) and EUR (VBCT: η² = 0.45; TCT: η² = 0.07) (p < 0.05). Training intensity did not differ between groups (p > 0.05), but VBCT showed lower training volume, fewer repetitions, and lower rating of perceived exertion, while exhibiting higher mean concentric velocity for each repetition within squat sets compared with TCT (p < 0.01).

conclusionsVBCT resulted in greater improvements in CMJ and EUR, while its effects on 1RM, SJ, and SLJ were similar to TCT. With lower volume and fatigue, VBCT may be a more efficient strategy for enhancing lower-limb strength and explosiveness during the competitive season.
