The Impact of Real-Time Visual Feedback on Maximal Force Output and Reliability During Isometric MidThigh Pull Testing in Resistance-Trained Men.

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
Accurate and valid assessment of the maximal force production is essential for athlete monitoring and training prescription in sports science. This study investigated the impact of visual feedback on force output and measurement reliability in isometric mid-thigh pull (IMTP). Twenty resistance-trained men completed three variations of the IMTP test (single, repeated, and 30 s all-out) across four sessions, with two sessions conducted with feedback and two without. Peak and mean force output was analyzed using peak and mean values. Data from the best testing day (i.e., highest force output in each variation) were used for comparisons between conditions, whereas test-retest reliability was assessed using data from the two sessions under the same condition. Visual feedback significantly enhanced most measures of peak and mean force outputs in all test variations (effect sizes ranging from 0.49 to 1.13 and p < 0.001-0.006). Reliability analyses of the single and repeated repetitions revealed that feedback reduced coefficients of variation (range: 2.57%-5.17% vs. 3.11%-6.92%) and yielded higher intraclass correlation coefficients (range: 0.961-0.983 vs. 0.898-0.987), indicating improved consistency both within sessions and between testing days. However, in the 30 s all-out test, feedback did not significantly improve reliability, possibly due to pacing strategies influenced by the real-time display. These findings demonstrate that real-time visual feedback enhances both performance and reliability in strength testing, with important implications for research and applied sports science.
