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

PAPE (post-activation performance enhancement) has gained attention in sports science due to its potential to enhance athletic performance. This study aimed to investigate the effects of different PAPE activation methods, including non-activation (CON), Dynamic High Inertia Load (DYN), Specific Isometric Contraction (ISO), and Back Squat (BSQ), on standing start sprint performance in elite female track cyclists. A randomised, counterbalanced experimental design was used, with eight elite female track cyclists (age: 23.3 ± 1.3 years; height: 1.66 ± 0.02 m; weight: 62 ± 1 kg). Each participant participated in four activation experiments, each performing one of the four activation protocols (CON, DYN, ISO, BSQ). Each experiment included four tests: pre-activation (PRE), post-activation at 4 min (POST 4), post-activation at 8 min (POST 8), and post-activation at 12 min (POST 12). Each test consisted of a 62.5-metre standing start time trial (TT), with TT time, peak power output (PPO), and peak torque (PT) measured. The Friedman test was used for the main effect analysis. The DYN significantly improved sprint performance, with TT time decreased at POST 4 (p = 0.019) and PT increased (p = 0.003). The ISO improvements in PT at POST 12 (p = 0.044), but the TT time remained unchanged (p > 0.05). The BSQ showed no significant performance enhancement in TT time or PT (p > 0.05). DYN activation is the most effective PAPE method for improving standing start sprint performance in elite female track cyclists, with optimal effects observed 4 min post-activation. While ISO may improve peak torque, it did not enhance sprint time.
