Normative H-Test Values in a Cohort of 113 Healthy Soccer and Track-and-Field Athletes at High Risk for Hamstring Injury.
Article in International journal of sports physical therapy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Hamstring strain injury (HSI) and re-injury are major issues in track and field (T&F) and soccer (SOC). Askling's return-to-sport H-test is reproductible and valid and can be used to objectively measure dynamic flexibility and kinematic outcomes. However, no normative values exist to support its interpretability across disciplines. Purpose: To establish normative values for the main H-test kinematic outcomes in healthy competitive track and field and soccer athletes, and to examine the effects of sport discipline and limb dominance on H-test performance. Study Design: Cross sectional, descriptive cohort. Methods: Competitive T&F and SOC athletes with no recent history of HSI (within the previous six months) performed H-test on both the dominant (DOM) and non-dominant (NDOM) limbs. The H-test consists of hip flexion at maximal velocity and amplitude, performed in a supine position. Mean range of motion (ROM), maximal angular velocity (Vmax) and angle at peak velocity expressed in degrees (APV°) and percentage of ROM (APV%) were recorded using frame-by-frame two-dimensional video-based angular analysis. Raw values and symmetry between limbs were reported and compared between disciplines using ANOVA. Results: One-hundred-and-thirteen athletes (94 males and 19 females, 20.1years, 176.6cm, 68.6kg, 46 T&F, 67 SOC) were included. H-test values were highly consistent, with 105.1°±10.8 (LSI=101.5%), 342.8°.s Conclusion: This is the first study to assess H-test kinematic outcome on a large sample of uninjured HSI at-risk athletes. Clinicians can use these values when interpreting results after hamstring injuries or during pre-season screening, particularly in male athletes. However, caution is warranted, as further studies are needed to confirm the link between H-test performance and injury risk, along with more research involving female populations. Level of Evidence: 2C.
