The impact of mental fatigue on the risk of non-contact anterior cruciate ligament injury during sharp stop-jump maneuver in male college students.
Article in BMC sports science, medicine & rehabilitation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
objectiveThe aim is to elucidate the effects of mental fatigue (MF) on lower limb biomechanics during stop-jump maneuver in healthy male college students and to evaluate its potential contribution to the heightened risk of noncontact anterior cruciate ligament injury (NC-ACLI).
methodsUsing a within-subject experimental design, MF was induced with a 45-minute Stroop task. The visual analogue scale for mental fatigue (VAS-MF), an infrared motion capture system, a three-dimensional force platform, and surface electromyography (sEMG) were employed to collect data on VAS-MF scores, as well as lower limb kinematics, kinetics, and electromyographic activity pertinent to NC-ACLI risk in 36 participants, before and after the MF induction. Paired t-tests and non-parametric statistical analyses were used for evaluation.
resultsVAS-MF scores increased significantly following MF induction (P < 0.001). After induction, participants demonstrated significant reductions in ankle dorsiflexion and knee flexion angle at the moment of peak vertical ground reaction force during stop-jump (P < 0.05). Conversely, peak vertical ground reaction force, knee extension moment, and knee abduction moment increased significantly (P < 0.05), while knee abduction and hip flexion angles remained unchanged (P > 0.05). Regarding muscle activation, rectus femoris sEMG parameters-including median frequency, mean power frequency, mean absolute value amplitude, and root mean square amplitude-were significantly elevated (P < 0.05), whereas tibialis anterior sEMG exhibited significant decreases in median frequency and mean power frequency (P < 0.05). No significant changes were observed in the sEMG signals of the biceps femoris or lateral gastrocnemius (P > 0.05).
conclusionMF significantly modulates certain biomechanical characteristics of the lower limb during stop-jump maneuver, potentially exacerbating the risk of NC-ACLI in healthy male college students. Targeted intervention strategies are recommended to mitigate ACL injury risks under mentally fatigued conditions.
