This systematic review and meta-analysis evaluated the impact of various exercise modalities on visceral adipose tissue (VAT) in adults with a BMI ≤27 kg/m². Thirteen studies involving 354 participants were analyzed, revealing a significant reduction in VAT associated with exercise (SMD = -1.590; p < 0.001). Aerobic training was particularly effective, while longer interventions yielded greater reductions.
Key findings
- Exercise significantly reduced VAT with a standardized mean difference of -1.590 (p < 0.001).
- Aerobic training consistently showed the most significant effects on VAT reduction.
- Longer intervention durations (>5 months) were linked to greater reductions in VAT.
- Heterogeneity among studies was substantial (I² = 86.4%).
Why it matters
Understanding the effects of exercise on visceral adipose tissue is crucial for managing body composition in individuals with normal weight obesity. This knowledge can guide exercise recommendations for improving metabolic health in at-risk populations.
What to keep in mind
The certainty of evidence is low due to methodological limitations, substantial heterogeneity, and potential bias in the included studies.
