Purpose: Creatine is the most important and commonly used supplement in athletes. The purpose of this study was to investigate the simultaneous effect of moderate altitude and short-term Creatine supplementation on musculoskeletal damage indicators in male climbers. Method: 16 male hikers with at least 2 years of hiking experience selected. Subjects (age 30.6±6.3 yrs.), (height 178.3±6/4 cm), (weight 77.6±11.25kg) were randomly divided into experimental (Creatine supplement) and control groups (placebo). The experimental group consumed 20 gr/day of the supplement for 5 days, while the control group received a placebo. The first blood samples were taken before the hiking session at the location of program. Hiking program consisted of ascending to Tochal peak at an altitude of 3961m. The second blood samples were taken after returning from the peak at an altitude of 3750 meters. The results were analyzed by SPSS software using independent t-test and K-S test with a significant coefficient of 0.05. Results: The results showed that there was a significant difference between LDH and AST enzyme levels in post-test compared to pre-test in both AST (P = 0.13) and ALT (P = 0.001) levels Control group. Also, climbing to 4000 m altitude with Creatine supplementation had no significant effect on LDH (P = 0.78) and AST (P = 0.86) levels between groups. Conclusions: The results showed that changes in muscle damage enzymes are independent of Creatine supplementation.

China is consolidating its position in the international system, taking advantage of a variety of channels in the process. The establishment of the Asian Infrastructure Investment Bank (AIIB) is a historical step by China in the international economic order. The AIIB, as an international financial and development institution attempts to engage and participate in the economic infrastructures of the member states. The question addressed in this research is, How could China's approach in establishing the AIIB be analyzed with respect to new economic developments in the last two decades?  The hypothesis is that the AIIB is considered as a network structure for making a centrality in the economic order for China, which facilitates the systemic evolution in international arena. The AIIB is therefore considered as a strategic turning point in the international economic order. This study argues that China is attempting to elevate and consolidate its economic role among the regional countries to institutionalize its centrality. Accordingly, it seems that China aspires to promote changes in the international system through a complementary and distinguished evolution. Therefore, the reliability of the AIIB is vital for this openness phase, and China is keenly going to maintain and strengthen the AIIB for coming games and required strategic plans.

China is actively engaged in Afghanistan, especially with the Neo-Taliban, which indicates significant changes in China's foreign policy. The Chinese government invited the Neo-Taliban delegations several times and tried to expand their role in their country. The present study examines the impact of China's active engagement with the Neo-Taliban, using Ibn Khaldun's Social Theory and Discourse Analysis. Questioning the nature of the active engagement of China with Neo- Taliban, we hypothesized an increase in insecurity overflow from Afghanistan to China, as well as an increase in insecurity complications in Afghanistan against China’s interests. It became clear that the Neo-Taliban's increasing interaction with China was to the detriment of Taliban and ultimately China. The Doha Peace Agreement requested the control and restriction of foreign fighters residing in Afghanistan, which for the foreign fighters, including the Uighurs, were a reminder of the restrictions imposed on them before the fall of the Islamic Emirate. However, Mullah Omar did not openly engage with China. This will delegitimize the Afghan Neo-Taliban and ultimately create a disperse Neo-Taliban with a fragile legitimacy, whose fragility does not seem to collapse, but will not serve China's interests either.
