Background : Cold sprays (CS) are widely used in sport competitions as an effective, simple, and high available treatment. Aim: The aim of present study was to investigate immediate and longtime effects of CS application onto the knee joint anterior-medial area of dominant leg on timing and activation pattern of selected muscles during one-leg landing. Materials and Methods: Thirty (15 control and 15 experimental) able-bodied male participated in this study. Electromyography activity of vastus medialis, rectus femoris, vastus lateralis, biceps femoris, semiendineus and medial gastrocnemius were recorded during one-leg landing tests (with dominant leg) for each of three conditions including before CS application (pre-test), immediately after (post-test 1), and 20 min later (post-test 2). To determine the effect of group and time on each dependent variable, three independent 2×2 multivariate repeated measures analyses of variance were performed (α < 0.05). Results : The results showed following trends rather than significant differences: the muscles in the experimental group had lower activity level and later onset immediately after CS application compared to before application, and they had higher activity level and sooner onset after 20 min from removing CScompared to immediate application. No significant interaction was found for normalized peak activation and time to peak activation ( P > 0.05). However, decrease in skin temperature after cold spray application was observed. Conclusion : These results show short-time cold application, which is so practical after many injuries for returning athletes to sport environment, may not predispose individuals to risk of re-injury or failed landing mechanism.

Purpose: The aim of this study was to investigate the acute effects of HIFT exercise, on creatine kinase (CK) and lactate dehydrogenase (LDH) in blood serum in overweight adult men. Method : Twenty-two untrained non-smoker overweight men (age, 42.9 ± 5.6 years; body mass, 94.2 ± 9.3 kg; body height, 178.9 ± 4.5 cm; and BMI, 29.04 ± 3.3 kg/m2) volunteered to participate in this study and performed a session of HIFT exercise with 80-85% HRmax consisting of three sets of 10 exercises. Blood samples were collected before and immediately after training to measure serum CK and LDH levels. Results: The HIFT protocol significantly increased serum CK (Pre: 114.6 U/L; Post: 124.3U/L; p< 0.05{t=-5.48, p=0.001}); Also, LDH had a significant increase (pre:213.4 U/L, post: 225.4U/L; p<0.05{t=-4.09, p=0.001}). Conclusion: It can be concluded that HIFT with AMRAP (as many repeats as possible) protocol will lead to a significant increase in some indicators of muscle damage such as CK and LDH levels in overweight men. This protocol can lead to muscle damage in overweight men.

Sport, and especially public sports, is very important because it increases life expectancy by promoting community health. The purpose of this study was to investigate the role of privatization in the development of participation in public sports in Alborz, Iran. This study was a mixed research (qualitative and quantitative). In the qualitative phase, the participants included 12 university faculty members and public sports administrators. In the quantitative section, 384 people were selected as a statistical sample based on Morgan table. Amiri et al.'s Privatization Questionnaire (2013) and a researcher-developed questionnaire were used to measure the research variables. Confirmatory factor analysis and structural equation modeling were used to test the research hypotheses. The results showed that privatization has a critical role in the development of participation in public sports in Alborz province. Therefore, expansion of the role and position of the private sector is one of the actions that can be taken in this field. It is suggested that sports, health and well-being officials seriously consider privatization in order to facilitate and increase the participation in public sports. 

The purpose of this research is to develop a strategic marketing plan for the Lifeguard and Diving Federation of the Islamic Republic of Iran. 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. 

Background: Research shows that there is a relationship between religion and spirituality with social behavior and mental health. Among the different religions, Muslims have the largest number in the world. Muslims pray five times a day. Aim: The purpose of this study was to review previous findings on the effect of Salat (Muslim prayer) on the mental and psychological health of people. Materials and Methods: More than 50 articles were reviewed and finally the most relevant articles were separated and analyzed. Results: The results indicate that there is a direct relationship between Salat and increasing the desire to live, hope, endurance of hardship, feeling happy and happiness, hope for recovery in patients. Also, prayer has an inverse relationship with anxiety and depression, despair, despair, dissatisfaction with life, discomfort with illness and problems. Conclusion: According to these findings, doctors and researchers in the health sector are expected to conduct new studies without religious and belief bias in order to understand and improve the mental and psychological conditions of patients, so that the mechanisms involved in these positive effects are revealed and possibly insight new in the process of improving people's mental and psychological conditions.

Background : There are conflicting findings regarding the effect of various training modalities on the cardiovascular disease mechanisms induced by undesirable modifications in extracellular matrix (ECM) factors such as MMP-9 and TIMP-1. Aim: This study was conducted to investigate the effect of different training protocols on the MMP-9 and TIMP-1 gene expression in the myocardium of Wistar male rats. Materials and Methods: Forty-eight adult Wistar male rats (aged: 8 weeks) were randomly allocated into two control (Con8w/base, n=8; and Con16w/end control, n=8) and four training groups (MICT, n=8; PICT, n=8; HIIT, n=8; and MIST, n=8). The training protocols consisted of 8 weeks (5 days/week) of Moderate-Intensity, Continuous Training (MICT: 37 min running with 65% vVO 2 max), Moderate-Intensity, Swimming Training (MIST: 30 min free-swimming), Progressive-Intensity, Continuous Training (PICT: 28 min running with a progressive increase in the incline of the treadmill by 2% per week), and High-Intensity Interval Training (HIIT: four running bouts 4 min with 90 to 100% vVO 2 max + 3 min with 50-65% vVO 2 max). Myocardial samples were isolated 24 hours after the last training session. Gene expression was determined using the real-time PCR method. All data (M±SD) were analyzed by one-way ANOVA and Tukey's post-hoc tests at α ≤0.05. Results : There were significant differences between MMP-9 and TIMP-1 expression in the animals myocardium after different exercise training protocols ( P <0.01). The lowest and highest MMP-9/TIMP-1 ratios were in the HIIT and MICT protocols, respectively. Conclusion: According to our findings, the HIIT protocol may play a more influential role in enhancing myocardial ECM-remodeling and fibrosis indicators during lifespan than the other exercise protocols.
