Neuromuscular adaptations to load-matched isometric vs. dynamic resistance training in Kho-Kho athletes: a pilot investigation.

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
Introduction: This pilot study compared the effects of load-matched isometric resistance training and dynamic resistance training on neuromuscular and sport-related performance in collegiate Kho-Kho athletes. Methods: Seventeen athletes completed the study and were included in the final analysis: nine in the isometric training group and eight in the dynamic training group. Both groups completed a five-week training program, with intensity regulated using modality-specific rating of perceived exertion scales: the Isometric Exercise Scale for the isometric group and the Borg CR-10 scale for the dynamic group. Pre- and post-intervention assessments included knee extension and flexion torque at multiple angles and velocities, squat linear sprint performance, vertical jump metrics, and reactive strength index. Results: The isometric group showed significant within-group improvements in 75° knee-extension peak torque and jump height, and both groups improved selected strength and sprint outcomes. Significant Group × Time interactions were observed for 75° right knee-extension peak torque and initial squat-start sprint speed, suggesting greater improvement in the isometric group for these selected outcomes. However, vertical jump improvement did not show a significant Group × Time interaction, and isokinetic torque outcomes showed no clear modality-specific superiority. Discussion: These preliminary findings suggest that RPE-regulated isometric training may provide short-term benefits for selected joint-angle-specific strength and initial acceleration outcomes in Kho-Kho athletes. However, definitive superiority over dynamic resistance training cannot be concluded from this exploratory pilot study.
