Review.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Purpose: This systematic review examined the effects of recreational soccer (RS) on anthropometric, metabolic, physical fitness, and mental health outcomes in youth with overweight/obesity. Methods: Following PRISMA 2020, this review searched seven databases, assessed quality with Cochrane RoB 2 and PEDro, performed meta-analysis in RevMan 5.4, used random-effects meta-analysis, and graded evidence certainty with GRADE. Results: Meta-analysis showed that RS was associated with significant reductions in BMI z -score [standardized mean difference (SMD) = −0.50, 95% confidence interval (CI): −0.93 to −0.08, p = 0.02; k = 4, n = 147], waist circumference (WC) [mean difference (MD) = −8.60 cm, 95% CI: −11.98 to −5.23, p < 0.00001; k = 6, n = 176], systolic blood pressure (SBP) (MD = −4.21 mmHg, 95% CI: −7.92 to −0.51, p = 0.03; k = 7, n = 216), insulin (SMD = −0.40, 95% CI: −0.77 to −0.04, p = 0.03; k = 3, n = 119), total cholesterol (MD = −19.90 mg/dL, 95% CI: −30.33 to −9.47, p = 0.0002; k = 3, n = 119), high-density lipoprotein (MD = 8.36 mg/dL,95% CI: 4.80–11.91, p < 0.00001; k = 4, n = 132), low-density lipoprotein (MD = −14.13 mg/dL, 95% CI: −24.44 to −3.81, p = 0.007; k = 4, n = 119), and flexibility (sit and reach) (MD = 1.90 cm, 95% CI: 0.66–3.13, p = 0.003; k = 3, n = 94). Conclusions: Regular RS participation improves anthropometric and cardiometabolic outcomes in children and adolescents with overweight/obesity, with robust evidence for reductions in WC and SBP. Findings for other outcomes are preliminary due to the limited number of studies and require further confirmation.
