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: Breast cancer as the most common cancer and deadliest malignancy among women is one of the most important health concerns in the world. Therefore, the present study was conducted in response to the question of whether the Pilates training method affects the memory, attention, and balance of women with lymphedema after modified mastectomy.Methods: In this quasi-experimental clinical trial, we studied 20 women with an average and standard division in (age, 43.03±5.61year), height (163.85±4.63 cm) and weight (67±3.95 kg). Our subjects referred to Shahid Motahari clinic, Shiraz, Iran in 2019 with lymphedema after modified mastectomy. They were randomly divided into two groups: Pilates and control. The experimental group performed Pilate’s exercises for 2 weeks, 3 days a week with 60 minutes long each session. Memory, attention, and balance before and after the training program were assessed using one-way analysis of covariance and paired t-test at a significance level of 0.05.Results: Statistical analysis of age, height, and weight showed no differences between the two groups. Statistical analysis of paired t-test indicated a significant difference in pre-test and post-test scores of the training group, yet this difference was not significant in the control group. Moreover, one-way analysis of covariance revealed a significant difference between the two groups in pre to post- tests in the tests of Stroop test [exercise (pre): 449.70±45, (post): 421.30±58.13; Control (pre): 461.30±23.17, (post): 457.10±22.20, P=0.014), n-back [Exercise (pre): 69.50±19.69; (post): 88.00±13.23; Control (pre): 79.40±17.48, (post): 82.00±10.74 P=0.016), and Flamingo [Exercise(pre): 18.49 ±18.92; (post): 51.57±43.02; Control (pre): 10.85±4.36, (post): 10.83±3.91, P=0.001]. Attention: (431.30±33.59), (461±11.12), memory: (72.50±17.34), (90±8.27), and static balance: (9.96±4.23), (29.39±7.00). In control group, the mean and standard deviation of the scores were as follows: attention: (465.90±10.56), (462.60±6.99), memory: (79.40±17.48), (85.90±4.45), and static balance: (10.85±4.36), (10.83±3.91).Conclusion: According to our findings, it could be concluded that women with breast cancer can use the benefits of Pilates along with other treatments.
