Effects of plyometric training combined with tDCS on lower-limb muscle activation and cardiopulmonary function in male amateur soccer players: a randomized controlled trial.
Article in Physical activity and 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
purposeThis study aimed to investigate the effects of combining transcranial direct current stimulation (tDCS) with plyometric training on lower-limb muscle activation and cardiorespiratory function in male amateur soccer players.
methodsThirty male amateur soccer players were randomly assigned to an experimental group (n = 15) or a control group (n = 15). The experimental group performed plyometric training combined with transcranial direct current stimulation (tDCS), whereas the control group performed plyometric training with sham stimulation. The intervention was conducted three times per week for four weeks. Lower-limb muscle activation (RF, VL, VM, and GCM) and cardiorespiratory function (MIP, MIFR, VO2max, Wmax, and MEC) were assessed before and after the intervention. Data were analyzed using a two-way mixed-design ANOVA.
resultsBoth groups showed significant within-group improvements in muscle activation and cardiorespiratory variables (p < 0.05). However, the experimental group demonstrated significantly greater enhancements in RF, VL, VM, and GCM activation compared with the control group (p < 0.05). Between-group comparisons also revealed superior improvements in MIFR and Wmax in the experimental group (p < 0.05), while VO2max increased significantly over time in both groups without between-group differences. A two-way mixed-design ANOVA indicated significant group × time interactions for muscle activation and selected cardiorespiratory indices (p < 0.05), supporting enhanced neuromuscular and physiological adaptations in the experimental group.
conclusionCombining tDCS with plyometric training enhanced lower-limb muscle activation and cardiorespiratory function more effectively than plyometric training alone in amateur soccer players.
