Causal relationship between strenuous exercise and muscle injury: a Mendelian randomization study with dual samples.
Synthesis in European journal of applied physiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundMuscle injuries, particularly those resulting from irregular bouts of strenuous exercise, have become a significant public health issue, especially among the athletic population. The physiological mechanisms linking intense physical exertion to muscle damage remain incompletely understood, necessitating further investigation to elucidate the causal pathways involved. PURPOSE: The objective of this systematic review is to explore the physiological mechanisms that may underlie the causal relationship between strenuous exercise and the incidence of muscle injury. STUDY
designA systematic review was conducted to synthesize available evidence on the topic.
methodsWe utilized advanced Mendelian randomization techniques with dual cohorts to analyze single-nucleotide polymorphisms (SNPs) significantly associated with strenuous exercise (P < 5 × 10^-8). Data on muscle injuries in the wrist and hand muscle, hips, and thighs were sourced from genome-wide association studies (GWAS) databases. A comprehensive sensitivity analysis was performed, incorporating inverse variance weighting, weighted median, MR-Egger regression, multicollinearity assessment, heterogeneity evaluation, and leave-one-out analyses.
resultsOur findings reveal a significant positive correlation between strenuous exercise and the risk of muscle injury in the hips and thighs (OR = 1.0046062, 95% CI [0.0004911795, 0.008700143], p = 0.028195794). In contrast, no causal link was identified between strenuous exercise and muscle injury in the wrist and hand muscle (OR = 0.9989059, 95% CI [-0.01131070, 0.009121317], p = 0.8336501).
conclusionThe present systematic review suggests that strenuous exercise is positively associated with an increased risk of muscle injury in the lower limbs. This association appears to be mediated through physiological mechanisms that are more pronounced in the lower extremities compared to the wrist and hand muscle. Further research is warranted to dissect the intricate physiological processes that contribute to this differential susceptibility to injury.
