Olympic Weightlifting Training Status, Bone Health, and Hormonal Profiles in Pubertal Male Weightlifters.
Article in Journal of bone metabolism, 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
backgroundAdolescence is a critical period for bone mass accrual, and mechanical loading through sport may enhance bone mineral acquisition. Olympic weightlifting provides high-magnitude, weight-bearing stimuli, but evidence in pubertal male athletes remains limited, particularly regarding its associations with endocrine factors related to growth and maturation.
methodsIn this cross-sectional study, 47 pubertal boys aged 13 to 15 years were classified into three groups: controls (N=16), non-elite weightlifters (N=16), and elite weightlifters (N=15). Biological maturation was assessed using Tanner staging. Bone mineral density (BMD) and bone mineral content (BMC) were measured by dual energy X-ray absorptiometry (DXA). Serum growth hormone (GH), insulin-like growth factor-1 (IGF-1), IGF binding protein-3 (IGFBP-3), and testosterone concentrations were determined. Annual training exposure (h/year) was calculated as the total number of hours of structured physical activity performed during the preceding 12 months.
resultsElite weightlifters were taller and had greater training exposure than non-elite weightlifters and controls. BMD and BMC at whole-body and regional skeletal sites were higher in the trained groups, with the highest values generally observed in elite weightlifters. Elite weightlifters also exhibited higher GH, IGF-1, IGFBP-3, and testosterone concentrations than controls. Total lean mass was strongly correlated with total and regional BMD and BMC, while IGF-1, IGFBP-3, and GH were positively associated with several bone outcomes.
conclusionsPubertal male weightlifters, particularly elite athletes, exhibited greater bone mineral status and a more favorable growth-related hormonal profile than age-matched controls. These findings support a positive association between training status, lean mass, and skeletal health during puberty; however, causal inferences are limited by the cross-sectional design.
