Resistance training with blood flow restriction increases the recruitment of fast-twitch fibers in hypoxia conditions. It also boosts the synthesis of muscle protein with anabolic hormone indices. Therefore, the purpose of the present study was to investigate the effect of low-intensity TRX suspension training with blood flow restriction on vascular endothelial growth factor (VEGF), hypoxia-inducible factor-1 (HIF-1), and body composition in active female students.

The present semi-experimental study was conducted on 36 female physical education students. The samples were selected purposefully and then randomly divided into three groups, namely high-intensity TRX suspension training, low-intensity TRX suspension training with blood flow restriction, and control. The training groups performed three sessions of TRX exercises with and without blood flow restriction for eight weeks. Analysis of covariance (ANCOVA) and Bonferroni post hoc test were used to compare the results between groups.

The findings showed that eight-week low-intensity TRX training with blood flow restriction caused a significant increase in VEGF (P=0.001), HIF-1 (P=0.001), and total body muscle mass (P=0.008) compared to the control group. The high-intensity TRX training group also increased VEGF (P=0.018) and HIF-1 (P=0.002) compared to the control group. However, the low-intensity TRX training group with blood flow restriction led to a significant increase in HIF-1 concentration compared to the high-intensity TRX training group (P=0.031). TRX suspension training with and without blood flow restriction had no significant impact on body mass index, body fat percentage, and total body water (P<0.05).

Overall, the results of this research showed that performing eight-week low-intensity TRX training with blood flow restriction improved the levels of VEGF, HIF-1, and muscle mass in active females. Therefore, these exercises can be a suitable training method to improve angiogenesis factors and body composition in females.

Athletes with a history of anterior cruciate ligament reconstruction need to return to sports after completing their medical rehabilitation, but they usually refuse to do so due to several months of absence from sports and fear of re-injury. Therefore, for these people, an ideal training protocol with appropriate intensity should be considered, so that they can prepare to return to sports, mentally and physically. The purpose of this research is to investigate the effect of suspension exercises using TRX (total body resistance exercise) on the fear of re-injury and return to sport criteria in athletes with a history of anterior cruciate ligament reconstruction.

The sample of the present study included 26 male athletes (football and futsal) aged 18 to 30 years with a history of anterior cruciate ligament reconstruction, who were randomly divided into two experimental groups of 13 people (Age 24.54±3.45 years, Height 179.15±4.27 cm, Weight 82.31±6.67 kg, BMI 25.58±1.04) and control (Age 24.62±3.79 years, Height 179.00±3.91 cm, Weight 82.62±10.57 kg, BMI 25.77±2.83). To check the level of fear of re-injury, the Tempa 11 questionnaire was used, and to evaluate the criteria for returning to sports, side jump, 8 jump, and single leg triple jump tests were used. After the pre-test, the athletes did exercises for 6 weeks and at the end, the post-test was performed. The comparison of the mean variables between the two groups in the pre-test and post-test was done using the analysis of covariance test at a significance level of 0.05.

The results showed that 6 weeks of suspension training using TRX led to a significant decrease in the scores of fear of re-injury tests of Tempa 11 (p=0.001), single leg side jump (p=0.001) and single leg 8 jump (p=0.001) and there was a significant increase in the single leg triple jump test score (p=0.001) in the experimental group compared to the control group.

Among the features of TRX trainings are the ease of doing these exercises, affordable cost, and the ability to perform them at any time and place. Also, considering that the results of this research showed that performing TRX trainings can improve the athletes' performance and reduce the fear of re-injury in Tempa 11 tests, side jumps, 8 jumps and single leg triple jumps, so to all trainers Sports and therapists are suggested to use the exercises used in this research to improve the performance and reduce the fear of athletes with a history of anterior cruciate ligament reconstruction.

Low back pain is one of the most common causes of disability in adults. There are many non-invasive interventions to improve low back pain; exercise therapy is one of the main approaches. But there is conflicting evidence regarding the effectiveness of different types of training methods. The purpose of this study was to investigate the effect of 8 weeks of suspension training on pain, core muscle endurance, and quality of life in patients with chronic non-specific low back pain.

30 women were selected to participate in this study 15 in the intervention group and 15 in the control group. The degree of pain was measured by the VAS index and the core muscle endurance was investigated by the McGill test and quality of life was measured with the SF-36 questionnaire in pretest and post-test. The experimental group then performed suspension exercises for 24 sections. Analysis of covariance (ANCOVA) was used between-group differences and paired T-test was used for inter groups differences.

The results of the T-test showed that there was a significant difference between the pre-test and post-test only in the suspensions training group in all of the variables. Also, the ANCOVA’s results showed that there is a significant difference between the experimental and control groups in the post-test.

The results of this study showed that the suspension exercises significantly improve pain and core muscle endurance and quality of life in patients with chronic non-specific low back pain.
