Aim: Due to the employment of female partners in the workforce, the number of couples who are both employed has increased recently. This problem has an impact on marital life and even job performance, even if it helps to improve family income. This study aimed to investigate the path analysis model of interpersonal trust, controlling behaviors, marital distress and job satisfaction in the dual-earner couples. Methods: The research is the correlational and structural equations type, and the statistical population of the research includes dual-earner couples working in the city of Isfahan in 1402, from which 120 people were selected by convenience sampling method. To measure the variables, the interpersonal trust scale (Johnson George and Swap, 1982), the controlling behavior scale (Graham Kwan and Archer, 2005), the marital distress questionnaire (Schneider, 1979) and the job satisfaction scale (Judge and Bono, 2000) were used. For data analysis, Pearson's correlation coefficient and structural equation modeling were used using SPSS software version 25 and Smart-Pls software version 3. The mediation analysis was done by bootstrap test. Results: The findings show that based on the value of 0.465 for the index G.O.F., the path analysis model of interpersonal trust, controlling behaviors, marital distress and job satisfaction is suitable, and the bootstrap test and confidence interval showed that controlling behaviors mediates the relationship between interpersonal trust and marital distress, and marital distress mediates the relationship between interpersonal trust and controlling behaviors with job satisfaction. Conclusion: It is recommended that in order to lessen marital misery and enhance work satisfaction, couples should get training aimed at fostering trust and reducing controlling tendencies.

Background: Neuromuscular training (NMT) and supplementation with essential minerals such as calcium (Ca), magnesium (Mg), and zinc (Zn) may enhance muscular reaction time (RT) and electromechanical delay (EMD). However, research on this topic, particularly among taekwondo athletes, is limited.Aim: This study aimed to evaluate the effects of NMT and Cal-Mg-Zn supplementation on RT and EMD in taekwondo athletes.Materials and Methods: Sixty athletes from a single taekwondo club in Tabriz, Iran, were randomly assigned to four groups of fifteen: Control, Ca-Mg-Zn, NMT, and Cal-Mg-Zn + NMT. NMT was conducted in 60 min sessions, four times a week, for six consecutive weeks, prior to main taekwondo training. RT and EMD were measured using electromyography before the intervention (T1), three weeks after (T2), and six weeks after (T3). Data were analyzed using SPSS with a confidence level greater than 0.95, employing repeated measures ANOVA and Bonferroni post hoc tests.Results: No significant differences in RT and EMD were observed among the groups at baseline (P> 0.05). In both post-test assessments, the Cal-Mg-Zn + NMT group exhibited significantly lower RT and EMD compared to the other groups (P< 0.05).Conclusion: The inclusion of NMT with zinc supplementation can effectively improve RT and EMD, thereby enhancing the athletic performance of taekwondo athletes.
