1 · What the graph read from 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.

2 · The registry

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

The study aimed to compare the effectiveness of two resistance training load progression methods-linear and step-on peak torque and power of knee extensors and flexors during the preseason of a Polish First League soccer team across two seasons. Differences between dominant and non-dominant limbs were analyzed, with progression tracked by tempo of movement and time under tension. Velocity-based training with a linear transducer ensured standardized intensity. Sixteen players from the same club participated in both seasons: 2021/2022 (linear) and 2022/2023 (step). Three-way ANOVA showed a significant leg × training × mesocycle interaction in the knee extensor and flexor peak torque. The post hoc test showed significant differences in peak torque between the dominant and nondominant legs during both progressive load methods - 2021/2022 and 2022/2023 seasons, both before and after the training intervention (p < 0.05). Knee extensors: The dominant leg showed higher values ​​compared to the non-dominant leg. However, there were no significant differences during the 2022/2023 season (p > 0.05). Knee flexors: No difference in peak torque values ​​between the dominant and non-dominant legs before the training intervention - 2022/2023 season. The conducted studies clearly indicate a greater effectiveness of the step load progression, however it also significantly affected bilateral asymmetry.
