Influence of a fatiguing exercise on lower limb electromyographic activities and co-contraction in overweight females during running.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThis study investigates the effects of a fatiguing exercise on lower limb electro-myographic activities and co-contraction in overweight females compared with normal weight females during running.
methodsForty-eight females were divided into two groups. The first group included individuals with a normal body-mass-index. The second group comprised individuals classified as overweight/obese based on body-mass-index. Electromyography data from the tibialis anterior, gastrocnemius medialis, vastus lateralis, vastus medialis, rectus femoris, biceps femoris, and semitendinosus muscles were collected during running at constant speed using a surface electromyography system before and after a running induced fatigue.
findingsThe results indicated significant main effects of the "Group" on tibialis anterior muscle activities during the loading phase (P = 0.040). Furthermore, the results showed significant main effects of "Fatigue" on rectus femoris (P = 0.028) and semitendinosus (P = 0.007) muscle activities during the loading phase. Paired-wise comparison demonstrated significantly greater rectus femoris and semitendinosus activities during the loading phase after the fatigue protocol. The results demonstrated significant main effects of "Fatigue" for general knee muscular co-contraction during early stance phase (P < 0.001). Paired-wise comparison demonstrated significantly greater general knee muscular co-contraction during early stance phase at post-test compared with pre-test. No significant main effect of "Group" and group-by-fatigue interactions were found for general and direct knee co-contraction during early stance phase (P > 0.05).
interpretationOverall, our findings indicate that both fatigue and being overweight result in running pattern differences, but these occur through different mechanisms at a neuromuscular level. Neuromuscular responses to fatigue during running in overweight adults and in normal weight adults can be evaluated together, in order to optimize the modality of treatment and rehabilitation processes in overweight adults to reduce and/or prevent the risk of running related injury.
