The aim of the present research was to evaluate the effectiveness of a therapy package for weight control based on Acceptance and Commitment with the Matrix Approach and Transcranial Direct Current Stimulation (tDCS) on Food Craving and Physical Activity in overweight individuals. The research Design was a quasi- experimental with pretest and posttest and An Active Control group. For this purpose, 40 persons were selected via availability sampling and in regard to include and exclude criteria. The instrument of the study were Baecke's Physical Activity Questionnaire (1982) and Food Craving Questionnaire-Trait of CepedaBenito (2000, FCQ-T). The experimental group received the intervention package in 12 online group sessions of 2-hour weekly sessions and 8 individual sessions of tDCS AR/CL stimulation (2Ma for 20 minutes) and the control group received only 8 individual tDCS sessions of AR/CL stimulation (2Ma for 20 minutes). The results of between- within group mixed analysis of variance showed that the combined intervention package of weight control based on Acceptance and Commitment with the Matrix Approach and Transcranial Direct Current Stimulation (tDCS) had a significant effect on physical activity and cravings of overweight people in comparison with tDCS alone. According to the results, it can be concluded that the therapeutic package of the present study can be a good option to increase Physical Activity and reduce Food Craving.

Research shows that narcissistic traits such as self-conceit and entitlement are associated with delinquency and aggression in childhood and adolescence. Therefore, the purpose of the present study was to investigate the relationship between narcissism and tendency to abnormal behavior and assertiveness with the mediating role of mindfulness among active students. The present study was a cross-sectional study of correlation with structural equation modeling. The statistical population was all male students in the second year of high schools in Torbat Heydarieh city, Northeastern Iran, in the academic year 2022-2023. According to the Morgan table, the size of the statistical sample was estimated to be 200 active male students who were selected stratified random sampling method. The data collection tools included Baer et al.'s Five Facet Mindfulness Questionnaire (FFMQ) (2006), Narcissistic Personality Inventory (NPI-40) from Raskin and Terry (1988), Rostami and Rad's Abnormal Behavior Tendency Questionnaire (2012), and Kotler and Giura's Assertiveness Questionnaire. Data analysis was done using structural equations with PLS version 3 software. The findings showed that there was a positive and significant relationship between narcissism and tendency to abnormal behavior, and there was no significant relationship between assertiveness and tendency to abnormal behavior. The mediating role of mindfulness on the effect of assertiveness and the tendency to abnormal behavior was confirmed, but the mediating role of mindfulness on the effect of narcissism on the tendency to abnormal behavior was not confirmed. In order to reduce the tendency toward abnormal behavior in active students, it is recommended to strengthen assertiveness by mindfulness training, as well as designing educational and behavioral therapy programs to control narcissism.

Aerobic power indicates the maximum amount of Oxygen intake that a person uses during strenuous physical activities under the sea. Accordingly, the significance of aerobic power in divers who spend much time under the water must be addressed. In order to investigate the matter, this study examines the correlation of aerobic power with increasing diving depth of divers and its relationship with their chest pain. The statistical population includes 70 students from a diving class of a Diving School in Bandar Anzali. The group consists of 20 male subjects randomly selected according to Morgan's table, aged 18 to 25, with no history of health issues, smoking, and professional sports activities. The results indicated a significant relationship between aerobic power and diving depth until the onset of chest pain; a significant inverse relationship between aerobic capacity and the intensity of chest pain; and a significant relationship was observed between aerobic capacity and duration of chest pain. These results are in favor of the effect of aerobic capacity in prevention of chest pain in divers.

Background: Trunk control defect is one of the neuromuscular defects that can cause sports-related injuries in athletes. Aim: This research investigated whether neuromuscular training affects several kinetic parameters in male athletes who had trouble controlling their trunks during a change-of-direction movement. Materials and Methods: The present study used a pre-test-post-test design and was conducted semi-experimentally. Purposefully chosen male athletes (n= 29) with trunk control defects were randomly divided into two groups: control (n= 14) and experiment (n= 15). A Kistler force plate was used to quantify kinetic variables. The exercises were performed for 6 weeks, 3 sessions per week (30 min each session). To analyze the data, dependent t-test and analysis of covariance and SPSS software version 21 were used at the significance level of P <0.05. Results: The findings indicated a significant decrease in the time to peak anterior-posterior force ( P =0.010), time to peak mediolateral force ( P =0.001), time to peak vertical force ( P =0.003), and rate of loading ( P =0.001) of the experimental group. The differences in all control group variables were insignificant, P >0.05. Conclusion: Performing neuromuscular training is likely to improve the direction change mechanism and prevent injury in athletes with trunk control defects.
