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

This study investigated the effects of three uphill gradients; shallow (SHG ~ 2.5%), intermediate (IHG ~ 5.1%), and steeper (STHG ~ 7.6%) on maximal velocity (Vmax), 800 m time trial (TT), and strength endurance (SE) performance in middle-distance runners. Forty moderately trained athletes (aged 16-20) were randomly assigned to SHG, IHG, STHG, or control (CG) groups (n = 10 each). Over 8 weeks, participants completed gradient-specific training. Vmax (30 m sprint), TT (800 m), and SE (1-min burpees) were assessed pre- and post-intervention. Two-way RM-ANOVA revealed significant main effects on Vmax (F(3,36) = 2.87, p = .049, [Formula: see text] = 0.20), TT (F(3,36) = 7.60, p < .001, [Formula: see text] = 0.39), and SE (F(3,36) = 5.19, p = .004, [Formula: see text] = 0.30). Post-hoc analysis showed STHG significantly outperformed CG in Vmax (mΔ = 0.93, p = .040), TT (mΔ = -0.29, p = .001), and SE (mΔ = 3.90, p = .007). IHG also improved TT vs. CG (mΔ = - 0.25, p = .007). The finding revealed that, uphill training, particularly steeper gradients, significantly enhances speed, endurance, and running performances. Therefore, coaches and athletes should customize training programs using uphill while carefully matching the strengths and weaknesses of the athlete and the demands of the event.
