Visuomotor expertise in volleyball: saccadic latency and absolute alpha power.
Article in Frontiers in psychology, 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
This study investigated differences in saccadic latency and absolute alpha power during eye movement preparation between young volleyball athletes and non-athletes. Two experimental paradigms were employed: fixed (memory-guided) and random (stimulus-guided) saccadic tasks. Thirty participants (15 athletes, 15 non-athletes) performed these tasks while electroencephalographic (EEG) activity was recorded from prefrontal and frontal cortical regions. Behaviorally, saccadic latency was significantly shorter in the random task compared to the fixed task; however, no significant group differences were observed. Electrophysiological analyses demonstrated that volleyball athletes consistently exhibited lower absolute alpha power at frontal and prefrontal electrode sites (Fp2, F7, F8, Fz, F4), suggesting heightened cortical engagement during visuomotor preparation. Both groups showed reduced alpha power in the random condition at lateral frontal sites (F7, F8), indicating enhanced attentional allocation to unpredictable stimuli. These findings imply that sports expertise may manifest as subtle neural adaptations not easily detected by behavioral measures like reaction time, thus underscoring the value of EEG in elucidating training-induced neurophysiological changes. Future research should utilize ecologically valid tasks and higher-density EEG recordings to further delineate the neural mechanisms underpinning sports expertise.
