Differences in neurocognitive performance and metabolic and inflammatory indices in male adults with obesity as a function of regular exercise.

New Findings: What is the central question of this study? Does regular exercise have benefits with regard to the neurocognitive problems related to obesity and are regular-exercise-induced neurocognitive changes associated with changes in the levels of metabolic/inflammatory biomarkers? What is the main finding and its importance? Although obese individuals with regular exercise showed higher C-reactive protein levels as compared to the healthy-weight individuals, only the obese individuals with a sedentary lifestyle showed deviant neurocognitive performance and higher metabolic and tumour necrosis factor-α levels. The P3 amplitude was correlated with the levels of leptin in the obese individuals with regular activity, implicating that the potential mechanism of neurocognitive facilitation as a result of regular exercise could be reduced serum leptin levels.

Abstract: Obesity has been shown to be highly associated with deterioration in executive functions, elevated energy metabolic indices and low-grade systemic inflammation.
