Background: Suspension training induce acute physiological and vascular stress. This study aimed to evaluate the effectiveness of eight weeks of low-intensity TRX training with BFR (LITRX+BFR) versus high-intensity TRX training (HITRX) in terms of sex hormones, power, muscle hypertrophy, and balance in young women.Methods: This study was carried out in 2018 using a semi-experimental pretest-posttest design. Thirty-six active female students were selected and then assigned to LITRX+BFR, HITRX, and control groups through random number generation. Training groups exercised three weekly sessions for eight weeks. Each session consisted of 7 low/high intensity suspension training. The control group only engaged in routine physical activity. After blood sampling, testosterone, cortisol, and estradiol hormones were measured by ELISA method. Muscular hypertrophy evaluated by anatomical method, power with jumping performance, and balance were measured via tecnobody-pk212. SPSS version 26 was used to analyze data using ANCOVA with Bonferroni post-hoc test.Results: The findings indicated that LITRX+BFR and HITRX had a significant increase in testosterone (P=0.000 and P=0.001), testosterone to cortisol ratio (P=0.001 and P=0.001), and estradiol (P=0.000 and P=0.003) while no significant change in cortisol levels (P=0.227). Moreover, muscular hypertrophy (P=0.001 and P=0.001), power (P=0.001 and P=0.000), static (P=0.011 and P=0.005) and dynamic balance (P=0.001 and P=0.001) significantly higher in both LITRX+BFR and HITRX compared with the control group. No significant differences found between suspension training with/without BFR in all variables.Conclusion: It seems LITRX+BFR had improvement in sex hormones levels, muscular hypertrophy, power, and balance as like HITRX. Therefore, LITRX+BFR can be a good alternative to HITRX in young females.

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.
