Influence of High-Impact Physical Activity on Pelvic Floor and Lumbar Muscle Mechanical Properties in Asymptomatic Nulliparous Women.
Observational study in International urogynecology journal, 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
introduction and hypothesisHigh-impact physical activity is a known risk factor for the development of pelvic floor disorders (PFDs) in women, affecting the pelvic floor muscles (PFMs). However, there is insufficient information to determine whether alterations in PFMs, or even in the lumbar muscles, can be detected before the onset of symptoms. The aim of the study was to identify whether high-impact physical activity influences the muscle mechanical properties (MMPs) of the lumbopelvic region in continent nulliparous women.
methodsAn observational cross-sectional study with a nonprobabilistic sampling of consecutive cases was designed. Fifty women who had practiced high-impact physical activity at least three times per week for more than 2 years were included in the high-impact group, and 50 women who did not practice high-impact activity were included in the control group. Data collection for both groups included sociodemographic data and MMPs (frequency, characterizing muscle tone; stiffness; logarithmic decrement, characterizing the inverse of the elasticity; relaxation time of stress; creep, characterizing fluidity) of PFMs and lumbar muscles, externally assessed using a hand-held tonometer device. Between-group comparison of the MMPs were calculated, together with intragroup correlations between the outcomes.
resultsThe MMPs of PFMs showed statistically significant lower tone (0.76 Hz, 95% CI 0.04, 1.48) and stiffness (23.76 N/m, 95% CI 1.10, 46.42) and were more viscoelastic (relaxation: -1.04 ms, 95% CI -1.98, -0.11; creep: -0.04 De, 95% CI -0.07, -0.02) in women who practiced high-impact physical activity. No lumbar MMPs showed statistically significant between-group differences.
conclusionsHigh-impact physical activity alters the MMPs of PFMs in nulliparous women, although not lumbar spinal MMPs, even before the appearance of signs.
