The effect of velocity-based strength training on lower limb maximal strength, power, and muscle thickness: a comparative study of sex-specific adaptations.

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
Purpose: This study aims to explore the effects of Velocity-Based Strength Training (VBT) on lower-limb strength, power, and muscle thickness in athletes of different sexes. It aims to identify sex-specific differences in training adaptations and explore how sex modulates training outcomes. Methods: A total of 28 participants with more than two years of systematic resistance training experience were recruited and divided into male and female groups according to sex, with 14 participants in each group. Four participants dropped out throughout the 8-week intervention, leaving a final sample of 12 males and 12 females. All participants completed an 8-week barbell back squat training program based on a VBT protocol. The training was performed thrice a week, with the load intensity progressively increasing from 65% to 75% of one-repetition maximum (1RM), and the training volume was set at 20% velocity loss (VL). Before and after the training intervention, measurements were taken for the following indicators: squat 1RM, jumping ability [countermovement jump (CMJ), squat jump (SJ), standing long jump (SLJ)], 30-meter sprint performance (T30), and rectus femoris thickness (RFT). Results: After the VBT intervention, both groups exhibited significant improvements in lower limb maximal strength, jump performance, sprint ability, and rectus femoris thickness ( Conclusion: VBT can significantly improve lower-limb strength, power, and muscle thickness in athletes of both sexes. However, training effects vary by sex: males show greater improvements in maximal strength and jump performance, while females demonstrate more prominent sprint gains.
