Introduction: The natriuretic pituitary is secreted from the heart and research has shown that exercise training affect these peptides. The aim of this study was to evaluate the effect of 8 weeks endurance, resistance and combination training on natriuretic peptides. Methods: A total of 36 students with a mean age of 25/36 ± 2/52 and BMI of 23/479 ± 0/959 were randomly divided into 4 groups: endurance (9 subjects), resistance (9 subjects), combination (9 subjects) and control (9 subjects) were divided. Subjects: Exercise, resistance, combination for 8 weeks and 4 sessions per week. The endurance group performed the program for 25 to 40 minutes and 65 to 85 percent of the maximum heart rate (HRmax) for each session, The resistance group was 50 percent one repetition (1-RM) and The combined group performed 2 sessions of endurance training and 2 sessions of resistance training each week. Blood samples were taken from subjects before and 48 hours after the test to measure ANP and NTproBNP hormones. T-test, one way ANOVA and LSD follow-up were used for data analysis using SPSS19 software. (Significance α ≤ 0/05). Results: Endurance training has a significant effect on ANP decrease (p≥ 0/05), however, there is no significant effect on BNP (P≤ 0/05); endurance training compared to resistance and combination has a greater effect on ANP reduction, as well as resistance training and The combination has no significant effect on ANP and BNP (p≤ 0/05). Conclusion: It seems that endurance training has a better effect on natriuretic peptides than resistance and combined exercises.

The tourism industry in the present century is recognized as one of the most thriving industries and the driving force of the world economy development. This emerging industry has been managed to attract the attention of many stakeholders from other industries by influencing other industries. Sport Tourism is also considered as a part of tourism that is created as a combination of sport and tourism, and is growing at a rapid rate and becoming a major and independent industry. One of the problems of the tourism in Iran, including Isfahan, is the imbalance in spatial organization and lack of hierarchy based on the interaction between tourism areas. Leveling of tourism infrastructure in different areas of a city and a balanced distribution of infrastructure and moderating inequality in different areas are of the important tourism development actions.

The purpose of this study was to evaluate the effect of Jadvar supplemental on Some Inflammatory factors following a session of an exhausting activity in men handball player. This study was conducted in a semi-experimental and double-blind design. The number of 14 handball players (mean age, height, weight and body mass index were 21. 42 ± 1. 56, 186. 55 ± 85. 5, 83. 25 ± 10 and 24. 09 ± 2. 93 respectively) Were divided into 2 groups of supplemental (Jadvar) and placebo (maltodextrin). Blood samples were collected from subjects before (fasting in the morning) and immediately after the maximum Bruce protocol. In the next step, supplementation group received the daily 3 capsules of 500 mg and the control group received 3 capsules of 500 mg maltodextrin for 7 days. 24 hours after consuming the last capsule, the subjects performed the maximum Bruce protocol to an exhaustion and, as in the first stage, the blood samples were collected before and immediately after the maximum Bruce stage. The results showed that a session of an exhausting activity could increase inflammatory factors (IL-6, CRP, TNF) (P<0. 05). While recived a one-week Jadvar supplemental leads to adjustment of increased inflammatory factors (P<0. 05). Also, this supplement could increase the duration of exhaustion in the supplement group (P<0. 05). According to the results of this study, since the level of inflammatory factors after the exhaustive activity in the supplement group, despite the increase, was significantly lower than the control group in male handball players, it is recommended that recived Jadvar supplemental with exercise.

Purpose: The aim of this study was to examine the response of the serum levels of Orexin-A and Apelin to the type and intensity of exercise in active young girls. Methods: eleven young active female students participated in the study, voluntarily. The Subjects performed 4 training interventions (moderate intensity continuous exercise, high intensity interval exercise, moderate intensity resistance exercise, and high intensity resistance exercise) with 3 days apart, using within subjects– counterbalanced crossover-design. Before and immediately after each exercise session, blood samples were collected and used for of Orexin-A and Apelin measurement through ELISA method. Two-way repeated measure ANOVA was used as statistical test at p0. 05). Conclusions: it seems that acute aerobic or resistance exercises with moderate or high intensity have no significant effects on the serum levels of Orexin-A and Apelin in active young girls. These results may be due to energy depletion (high energy cost for all four protocols) in each session of activity.
