This systematic review and meta-analysis evaluated the impact of physical activity (PA) characteristics on cardiometabolic health in adults aged 18-65. The analysis of 144 studies revealed that frequent PA bouts significantly reduced blood glucose levels (SMD -0.22), while longer and more intense bouts decreased triglycerides (SMD -0.27). The findings suggest tailored PA strategies can enhance cardiometabolic outcomes by interrupting sedentary behavior.
Key findings
- Frequent PA bouts reduced blood glucose levels (SMD -0.22).
- Longer and/or more intense PA bouts decreased triglycerides (SMD -0.27).
- Systolic BP improved with PA (SMD -0.29) across various types.
- Higher PA intensity was associated with improved endothelial function (SMD 0.88).
Why it matters
Understanding how different characteristics of physical activity affect cardiometabolic health can guide clinicians in recommending effective interventions to reduce the risks associated with sedentary behavior, ultimately improving patient outcomes.
