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

objectiveThis study examined the effects of vibration frequency and additional loading on lower limb muscle activation and coactivation during whole-body vibration (WBV) training in recreational runners.

methodsTwenty-five male runners performed WBV training at six frequencies (0-50 Hz) under two loading conditions (no load vs. 20% body mass). Surface electromyography was used to record electromyography root mean square (EMGrms) in 11 lower limb muscles. Coactivation of six muscles was analyzed using the time-varying multi-muscle coactivation function. 1D statistical parametric mapping and two-way repeated-measures ANOVA were used to assess differences.

resultsEMGrms was significantly influenced by vibration frequency and loading. Additional loading increased activation in the gluteus maximus, quadriceps, hamstrings, and soleus (p < 0.001). Frequency effects were notable in the gluteus maximus and hamstrings, with 10-30 Hz inducing higher muscular activation than the no-vibration case (p < 0.01). Coactivation was significantly high with loading (p < 0.001), particularly during the eccentric squat phase, but frequency had no significant effect.

conclusionAdditional loading enhances muscle activation and coactivation, and vibration frequency primarily affects muscular activation. These findings highlight the importance of external load and frequency in optimizing WBV training for enhancing sports performance and preventing injuries in runners.
