Abstract
Background: Heat shock proteins (HSP) can act as a cellular protection by facilitating reconstruction of denatured proteins. The aim of this study is evaluation of protective effects of glutamine consumption on HSP70 and cortisol response.
Materials and Methods: In this experimental study, 28 soccer players divided into 4 groups: control (n=7), supplement (n=7), exercise (n=7) and exercise supplement (n=7). Supplements (glutamine) and placebo (Dextrin) to a 0.5 gram per kg of body weight and volume of 5 ml per kg of body weight one hour prior to the exercise protocol was used. exercise protocol include a 3-stage 20-minute run at 80% of maximum heart rate and rest 5 minutes. Blood samples of basal (after 12-14 hour overnight fasting), post exercise, and 90 minutes after exercise were gathered and HSP70 of serum and cortisol were measured with Elisa and RIA respectively. Data were analyzed with multivariate repeated measures (MANOVA) at p&le0.05 level.
Results: There was significant difference in HSP70 amounts between supplement group and exercise supplement group compared to the control group (p&le0.09, p&le0.019) and also supplement group with exercise supplement group (p&le0.032). Also there was significant difference Between post exercise and 90 min after exercise stages compared to basal stage (p&le0.08, p&le0.06) and between post exercise and 90 min after exercise (p&le0.030). In cortisol amounts between basal and 90 min after exercise stages (p&le0.026) there was significant difference.
Conclusion: Glutamine sitimulate of HSP70 induction and combination of supplement with exercise has a great HSP70 response thus athletes who wish to compete or have intense exercise, glutamine consumption is recommended.

Abstract
Background and Aim : Despite progressive improvement in medical therapy and standard care, Exercisebased rehabilitation programs have been shown to to have beneficial cardiovascular effects in patients with myocardial infarction through a multifactorial effect. This review study aimed to evaluate exercise-based cardiac rehabilitation strategies in patients with myocardial infarction with special focus on high intensity interval training, as a growing field of research was conducted.
Material and Methods: This is a systematic review study on articles published, without limitation Year, by searching in reputable databases such as PabMed, Science Direct, Google Scholar, Scopus, Springer. Also in the process of searching for articles on the keywords microRNAs (miRNA) and myocardial infarction "," cardiac rehabilitation and myocardial infarction "," cardiac rehabilitation and high-intensity interval training (HIIT) ", high-intensity interval training (HIIT) and Myocardial infarction was used.
Ethical considerations: All Ethical principles in writing this article have been observed according to the instructions of the National Ethics Committee and the COPE regulations.
Results: High-intensity interval training (HIIT) is a safe and effective exercise strategy to improve cardiac function in MI, and to prevent abnormal changes in mass, size, geometry, and cardiac function after MI, and Applies significant changes in molecular targets and cell pathway.
Conclusion: Therefore, HIIT targets myocardial necroptosis due to oxidative stress, protects the heart against adverse left ventricular regeneration after MI, and can be considered an integral part of post-MI cardiac rehabilitation programs.
