Background: Efficient exercises for enhancing lipolysis could be implemented in the measures taken regarding obesity reduction and the related risk factors. The present study was conducted to compare the response of lipolysis inhibitory and excitatory hormones, including insulin, epinephrine, and glycerol, as index of lipolysis to high-intensity interval resistance exercise (HIIRE) and traditional resistance exercise (TRE) protocols in overweight girls. Methods: This was a kind of acute and semi experimental study, which was performed during the winter of 2019. Eleven overweight young girls with a mean weight of 68.54±4.3 kg participated in this study objectively and voluntarily. The participants took part in HIIRE and TRE programs separately with at least a one-week interval. Blood samples were taken before and immediately after an exercise session in order to measure the levels of epinephrine, insulin, and glycerol. For analysis of the data, we utilized statistical method of paired t-test. Results: Statistical analysis of the data revealed a reduction in the level of insulin (P=0.009) and an increase in that of glycerol (P=0.04) after HIIRE. There were no significant changes in epinephrine following HIIRE (P=0.75) and TRE (P=0.15). Moreover, there were no significant differences concerning the changes of epinephrine (P=0.93), insulin (P=0.15), and glycerol (P=0.13) between HIIRE and TRE protocols (P>0.05). Conclusions: Regarding the decrease in lipolysis inhibitor (insulin) and the increase in glycerol, as an index of adipose lipolysis following HIIRE, it could be recommended as an effective exercise for reducing adiposity.

Background: Ramadan fasting is a religious practice and an exceptional ritual compared to all other religious conventions. The aim of fasting in Ramadan is to establish a proper religious model of self-control and healthy lifestyle.
Objectives: The purpose of this study was to compare the biochemical neurohormones between women with polycystic ovary syndrome (PCOS) with and without fasting.
Materials and Methods: This study was conducted during July 2011 at the Infertility Center of Royan Institute, and comprised 40 patients diagnosed with PCOS, aged from 20-40 years without any special disease. The study group included 20 women with PCOS and fasting during Ramadan. The control group consisted of 20 non-fasting women with PCOS. The study on the effects of fasting on patients with polycystic ovary syndrome involved demographic data and biochemical stress hormones including cortisol, adrenaline, noradrenaline, beta-endorphin and insulin.
Results: In patients with PCOS, mean of cortisol in subjects with and without fasting were 8.2 ± 4.4 and 11.2 ± 4.7, respectively (P = 0.049). Also the respective median of nor-adrenaline in fasting and non-fasting patients were 1273.5 and 1503.5 (P = 0.047). However, no significant differences were found in adrenalin (P = 0.151), beta-endorphin (P = 0.543) and insulin (P = 0.818) between PCOS two groups.
Conclusions: This study showed that Ramadan fasting is a well known practice to reduce stress hormones in women with PCOS. So, Ramadan, beside its spiritual benefit is a blessing from God for improving human lifestyle.
