The current research is a mixed study with the strategic approach. By conducting a combined method including expert opinion, review of valid documents, and using some matrices related to the formulation of a strategic plan, the formulation of a strategic plan for the marketing of the Lifeguard and Diving Federation has been discussed. The research participants included 15 members of the Board of Directors of the Lifeguard and Diving Federation, managers and sports marketing specialists. In quantitative phase, the measurement tool consisted of a researcher-developed questionnaire that was designed and adjusted using the Delphi method. According to the final score of the evaluation matrix of internal factors (2.47) and the evaluation matrix of external factors (2.44), it was determined that the strategic marketing position of Lifeguard and Diving Federation was in the WT position. The results of SWOT analysis have led to the formulation of 3 SO strategies, 3 ST strategies, 3 WO strategies, and 4 WT strategies. 13 strategies to fulfill the mission of the long-term marketing goals of the federation have been developed and an operational plan has been prepared for each of them. It was concluded that the lifeguard and diving federation needs to use defensive strategies and close to the competitive area (ST) in the field of action. 

The present study brings forward a model of workplace health with an approach to staff’s physical activity improvement. this study was an applied and descriptive research that has been conducted with a mixed approach for data collection (qualitative and quantitative). The methodology is performed qualitatively on the basis of grounded theory of Glaser approach. The research participants in qualitative included 18 subjects selected through judgmental sampling method with snowball approach. In addition, the sample in quantitative section, 384 subjects were studied through convinience sampling based on  Krejcie and Morgan table. The analysis in the quantitative section is second-order confirmatory factor analysis. According to the results, components of workplace health comprising the physical environment with sub-components of preparing infrastructure along with strenuous company; the psycho-social environment with sub-components of education, culturalization, encouragement along with support; the health resources with the sub-components of evaluation, supervision and alignment of plans; and participation of the company which comprises management and planning.

The aim of this research was to determine the relationship among transformational leadership style with organizational culture and organizational commitment. The population consists of 745 the employees of the Ministry of Youth and Sports of Iran. The sample size of 256 staffs was determined using stratified random sampling. In order to collect the needed data, three Transformational Leadership, Organizational Culture and Organizational Commitment Questionnaires were used. The validity of these questionnaires was confirmed by foreign and domestic researches. Cronbach's alpha reliability test of transformational leadership, organizational culture and organizational commitment were respectively 0.97, 0.97, and 0.92. In addition, data were analyzed using statistical tests such as descriptive statistics, Kolmogorov Smirnoff, Pearson correlation coefficients using SPSS Software. The findings of this study showed that there was a positive and significant relationship between transformational leadership and organizational culture (p≤0.01, r= 0.80). Besides, there was a positive and significant relationship between transformational leadership and organizational commitment (p≤0.01, r= 0.46), too. Likewise, there was a positive and significant relationship between organizational culture and organizational commitment (p≤0.01, r= 0.57). However, organizational culture is stronger predictor than transformational leadership for organizational commitment. Finally, in accordance with the responses of staffs of the Ministry of Youth and Sports, it can be said that if leaders create an organizational culture in which creativity and satisfaction were high as well as to taking advantage the organizational rewards and job good conditions, employees would be able to stimulate higher levels of organizational commitment.

Background: Anodal transcranial direct current stimulation (a-tDCS) is a new neuro-modulatory technique.Aim: This study aimed to investigate the effect of a-tDCS on dynamic balance after exhaustion.Material and Methods: Fifteen endurance-trained men voluntarily attended five separate sessions. In the first session, Maximal aerobic speed (MAS) was measured. Then, the participants were randomly assigned to four different conditions: 1. Mental fatigue (MF)+a-tDCS, 2. MF+sham (s-tDCS), 3. a-tDCS, and 4. s-tDCS. In each session, after dynamic balance measurement, the participants were exposed to the conditions and received 20 min of anodal tDCS over the dorsolateral prefrontal cortex (DLPFC). Then, the participants performed a submaximal endurance activity at 70% of MAS until exhaustion. Immediately after exhaustion, dynamic balance was measured again.Results: After exhaustion, the dynamic balance of the right leg under the a-tDCS condition was significantly higher than the MF+s-tDCS (P= 0.008). The dynamic balance significantly decreased from pre- to post-test in MF+s-tDCS and s-tDCS conditions (P= 0.0001). In the left leg, the dynamic balance under the a-tDCS condition was significantly higher than MF+s-tDCS (P= 0.025).Conclusions: Anodal stimulation of the DLPFC could be beneficial for the dynamic balance and may have a protective effect against the negative consequence of exhausting activity on the dynamic balance in endurance-trained men.

The present research examines the relationship between metacognitive beliefs and anxiety sensitivity with conscientiousness of lifeguards. This is a descriptive-correlational research and has been carried out by the field method. The statistical population of the research included all female lifeguards in the east of the country and at different work levels (310 people). Next, according to the type of statistical population, the sample size was calculated using Morgan's table to the number of 150 people, and they completed the questionnaires of metacognitive beliefs, anxiety sensitivity and conscientiousness. Data were analyzed through Pearson correlation and multiple regression statistical tests simultaneously. The results showed that there is a significant correlation between metacognitive beliefs and anxiety sensitivity with conscientiousness (p≤0.05). Positive metacognitive beliefs have a positive and significant relationship with conscientiousness, while the relationship between negative metacognitive beliefs and anxiety sensitivity with conscientiousness is negative and significant. Since lifeguards should be at the peak of responsibility, knowing the issues that can negatively affect their conscientiousness can be a solution or suggestion to improve their performance. Therefore, according to the results of the research, it is suggested to discuss the psychological preparation of lifeguards, especially in the cognitive aspect. There should be more emphasis
