The Effect of Combined Aerobic Exercise and Calorie Restriction on Mood, Cognition, and Motor Behavior in Overweight and Obese Women

weight (TBF-300 body composition scale; Tanita, UK Ltd., UK) was measured while the participants wore only underwear and were barefoot.

Mood was assessed using the 24-item Brunel Mood Scale, which estimates anger, confusion, depression, fatigue, tension, and vigor. Items are rated on a 5-point Likert scale anchored by 0 (not at all) and 4 (extremely), according to how participants feel "right now."

Venous blood samples (5 mL) were collected and allowed to clot at room temperature. Serum was then separated by centrifugation for 15 min at 1,200 g (room temperature) and stored at -80°C until analysis. BDNF were measured using an enzyme-linked immunoassay system (Gemini; Stratec Biomedical, Birkenfeld, Germany).

Body height was measured in meters with an accuracy of 5 mm

Automated Neuropsychological Assessment Metrics Version 4 (ANAM-4; Vista Life, USA) was used to measure neurocognitive skills: motor reaction time, mental flexibility, mathematical processing, working memory, visual scanning and associative learning skills. Participants were familiarized with the test battery twice before the experiments.

Assessment of brain activity was performed on a continuous wave system (fNIR Imager 1100, fNIR Devices LLC, Potomac, MA, United States) using a flexible 16 optode probe set. The sensor has a temporal resolution of 500 ms per scan with a 2.5 cm source-detector separation allowing for approximately 1.25 cm penetration depth and 16 measurement locations on a rectangular grid covering the forehead region, designed to observe dorsal and inferior frontal cortical areas.

During the speed-accuracy task, the participant was required to position the handle symbol (0.0035 m in diameter) in the start zone on the computer screen. The participant then had to react to the target (a green circle, 0.007 m in diameter) on the computer screen as fast as possible and to push the handle of the device so that the circle of the handle symbol reached the target as quickly and accurately as possible. The distance from the start zone to the target was 0.17 m. The endpoint of the movement was reached when the center of the handle symbol stopped in the circle and stayed there for at least 0.02 s.
