Effects of concurrent training on fat mass and its distribution in individuals with overweight or obesity: a systematic review, meta-analysis, and exploratory regression analysis.
Synthesis in BMC public health, 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
backgroundObesity is a major global health challenge. While aerobic and resistance exercises are commonly used for obesity management, the effects of concurrent training (CT, combining both modalities) on fat mass and its distribution in individuals with overweight or obesity remain unclear. This study examined the effects of CT’s on visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT), and tried to identify optimal exercise prescriptions.
methodsSix databases were systematically searched through September 2025. Randomized controlled trials comparing CT interventions with sedentary or usual-care controls in individuals with overweight or obesity were included. Meta-analyses calculated standardized mean differences (SMD) for VAT and SAT reduction. The percentage ratio of visceral/subcutaneous fat loss (%ΔV/%ΔS) was calculated, and predictors were explored through regression analysis.
resultsEighteen studies were included. CT significantly reduced VAT (SMD = -0.36, 95% CI: -0.59 to -0.13, P < 0.01, I2 = 57%) and SAT (SMD = -0.26, 95% CI: -0.40 to -0.12, P < 0.01, I2 = 1%), with greater percentage reduction in VAT than SAT (%ΔV/%ΔS = 1.96 ± 1.18). Optimal effects were observed with ≥ 3 sessions per week, ≥ 60 min per session, > 180 min per week, > 15 weeks, and vigorous-intensity aerobic exercise combined with moderate-to-low-intensity resistance training. Intervention frequency and baseline VAT/SAT ratio significantly predicted fat distribution changes.
conclusionsCurrent evidence suggests that CT can effectively reduce fat mass and may preferentially decrease VAT compared to a sedentary lifestyle in individuals with overweight or obesity. Our findings support CT as a promising and scalable strategy for population-level obesity management, particularly for high-risk groups such as postmenopausal women and older adults. Furthermore, the identified exercise prescription parameters provide practical guidance for populations aiming to reduce adipose tissue.
