Most studies demonstrated that overweight correlated to the risk of the physical health, such as hypertension, stroke, type II diabetes,certain types of cancer, and even affected mental health. Recent years, several studies found that overweight individuals had lower inhibitory control abilityand accuracy rate, and slower reaction time in the cognitive behavior performance task compared to the individuals with normal weight. In addition, according to the analysis of the event-related potentials (ERPs), individuals with obese had larger amplitude of N2 wave and smaller amplitude of P3 wave, which indicated poor inhibition control and attention, respectively. However, most studies focused on obese children. There was limited study on overweight female adults. Exercise intervention is a common strategy of weight loss strategy. High intensity interval training (HIIT) has been confirmed to be able to improve health outcomes and cardiovascular function, as well as the bebefits in enjoyable and time-efficient. Nevertheless, some scholar suggested that modified to minor HIIT might be more implimentl for the overweight females and sedentary adults. Therefore, this study aims to investigate the effects of 12-week moderate intensity body weight training combine aerobic exercise interval training on fitness and event related potential of executive control in overweight female adults. Methods: The study were recruit forty-one female adults aged 20-45 years and then divide into normal weight group (BMI<25 kg/m2) and overweight group (BMI≥25 kg/m2) by body mass index (BMI). Both groups accepted a 30 minutes supervised MIIE, 5 days per week for 12 weeks. And then accepted another self-training MIIE for 12weeks. The fitness and cognitive behavior performance tasks (Go/nogo task) were assessed before and after the supervised MIIE. The mixed repeated measures analysis of variance (RM–ANOVA) were used to detect the differences in group, condition and electrodes, the paired t-test was used to detect the differences within group, and the independent t-test was used to detect the differences between groups. All significance levels was set at α= 0.05. Results: There weresignificant reduction of all participants in body weight (pre: 66.7± 10.4kg vs. post: 65.5± 9.7kg, p <.05), BMI (pre: 25.8± 3.9 kg/m2 vs. post: 25.4± 3.6 kg/m2, p <.05), waist circumference (pre: 81.1 ± 8.3cm vs. post: 77.6 ± 7.0 cm , p <.05), abdominal circumference (pre: 89.7 ± 9.5 cm vs. post: 84.6 ± 7.8 cm , p <.05), and hip circumference (pre: 104.5 ± 7.5 cm vs. post: 101.2±6.7cm ,p<.05) after the 12-week supervised MIIE without group difference. In fitness, the strength in abdominals (pre: 23.0±6.2 reps vs. post: 26.4±6.4 reps, p <.05) and lower extrmity (pre: 24.0±4.7reps vs. post: 30.4±4.0, p<.05), and predicted VO2max (pre27.1 ± 3.9 ml/kg/min vs. post: 32.0± 4.7 ml/kg/min, p<.05) were significantly improved after the 12-week MIIE in all participants without group difference. The P3 ampulitude was significantly improved (pre: 2.92±2.2μV, post: 5.19±2.9μV, p<.05) in all participants after the 12-week MIIE. The attendance rate in supervised (89.5 ± 14.2 %) was higher than that in self training (58.5 ± 32.6 %, p < .000). Conclusion: The 12-week moderate intensity body weight training combined aerobic exercise interval training showed a positive effect on weight, body circumferences, fitness and neurocognitive functions in attention both in overweight and normal weight sedentary female adults.
