Physical activity (PA) plays a crucial role in managing metabolic syndrome (MetS), a cluster of conditions that increase the risk of diabetes, cardiovascular disease, and other health issues. MetS is characterized by obesity, insulin resistance, hypertension, and dyslipidemia. Lifestyle interventions, including increased PA and reduced caloric intake, are effective in improving metabolic outcomes. Regular moderate PA enhances insulin sensitivity, lipid profiles, blood pressure, and body composition. Systematic PA improves quality of life, reduces adverse effects on bone mass, and promotes better body composition. This review summarizes the current understanding of PA's impact on MetS components and the latest recommendations for PA in MetS patients. PA is defined as any bodily movement that requires energy expenditure, while exercise is a structured form of PA. Regular moderate PA improves insulin sensitivity, lipid profiles, and blood pressure. Low physical fitness is a major risk factor for MetS and overall mortality. Exercise reduces visceral fat, decreases pro-inflammatory adipokines, and increases anti-inflammatory cytokines. It also promotes the release of myokines, which protect against inflammation-related diseases. PA is strongly associated with reduced obesity risk. Increased energy expenditure and reduced caloric intake help reduce excess body fat. Exercise improves lipid profiles by increasing lipoprotein lipase activity, which hydrolyzes chylomicrons and VLDL. PA also lowers blood pressure through vascular remodeling, reduced peripheral resistance, and improved endothelial function. Exercise reduces sympathetic nervous system activity and increases parasympathetic activity, which helps regulate autonomic balance. PA improves insulin sensitivity by reducing body fat and increasing cellular insulin sensitivity. Exercise enhances glucose uptake and mitochondrial oxidative capacity, which inhibits gluconeogenesis. PA also improves glucose tolerance and maximal oxygen uptake. Resistance training increases muscle mass and lean body mass, which improves metabolic health. It enhances insulin sensitivity, glucose tolerance, and lowers blood pressure. Recommended PA for MetS includes moderate-intensity aerobic exercise, resistance training, and high-intensity interval training (HIIT). Moderate-intensity aerobic exercise is particularly effective in reducing body weight, visceral fat, and improving blood pressure. Resistance training is recommended to maintain lean body mass during weight loss. HIIT is beneficial for improving metabolic and cardioprotective outcomes. The World Health Organization recommends at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of high-intensity aerobic exercise per week, along with muscle-strengthening activities. Sedentary behavior is a significant risk factor for MetS, and reducing sitting time is recommended. Non-exercise activity thermogenesis (NEAT) is crucial for energy expenditure and preventing MetS components, particularly obesity. In conclusion, PA is a low-cost and accessible intervention that can modify all components of MetS. It improves metabolic health, reduces cardiovascular risk, and enhances overall well-being. Regular PA is essential for preventing and managing MetS, especially in high-risk populations.Physical activity (PA) plays a crucial role in managing metabolic syndrome (MetS), a cluster of conditions that increase the risk of diabetes, cardiovascular disease, and other health issues.
