Key result
Two months of moderate-intensity aerobic exercise improved body weight and peak oxygen consumption (P < .05) but had no impact on cognitive or motor performance in overweight and obese women.
Why the study?
The effect of globally recommended levels of physical activity on cognition and motor behavior was not completely understood.

Does 300 minutes per week of moderate-intensity aerobic exercise improve cognitive and motor performance in overweight and obese middle-aged women?
Two months of globally recommended physical activity improved cardiovascular fitness and decreased sympathetic activity but did not improve cognitive or motor functions in overweight and obese middle-aged women.
BACKGROUND: The effect of globally recommended levels of physical activity on cognition and motor behavior is not completely understood. Therefore, the main aim of this study was to assess the effect of 300 minutes per week of moderate-intensity aerobic exercise on cognitive and motor performance among overweight and obese working-age women. METHODS: Overweight and obese participants aged 38-56 years were randomized to either a control or an experimental group performing aerobic exercise at 50% to 60% of the peak oxygen consumption for a 2-month period. Changes in aerobic fitness, cardiac autonomic function, brain-derived neurotropic factor levels, and cognitive and motor performance were assessed. RESULTS: Although aerobic exercise reduced body weight (P < .05) and improved peak oxygen consumption (P < .05), the brain-derived neurotropic factor levels and cognitive and motor performance remained unchanged. Heart rate and blood pressure decreased (P < .05), whereas heart rate variability indices were not affected. No significant correlations between changes in heart rate variability indices and cognition were observed. CONCLUSIONS: Two months of moderate-intensity aerobic exercise decreased sympathetic activity and improved cardiovascular fitness but had no impact on cognition or motor control among these middle-aged, overweight, and obese women.

Žlibinaitė et al. (2020) conducted an RCT in Overweight and obesity. Moderate-intensity aerobic exercise vs. Control was evaluated on Cognitive and motor performance. Two months of moderate-intensity aerobic exercise improved body weight and peak oxygen consumption (P < .05) but had no impact on cognitive or motor performance in overweight and obese women.
