Abstract:
Introduction and purpose: Back pain is one of the most common musculoskeletal disorders. Since it is difficult for people with back pain to bear weight, a treatment that can strengthen the muscles of the lumbar region while bearing weight without pain is of great interest. Therefore, the purpose of this research was to compare the effect of eight weeks of traditional resistance training and TRX on the performance of people with non-specific chronic back pain.
Research method: 45 football players aged 20 to 30 years with chronic back pain were purposefully selected and placed in 3 groups, TRX exercises, traditional exercises and a control group of 15 people each. Before and after the training period, performance variable was evaluated by square test, and trunk endurance was evaluated by Magill tests. Further, the subjects of the experimental groups performed their respective exercises for 8 weeks and 3 sessions of 45 minutes each week, while the control group went through the research process without specialized back pain exercises. For the inferential analysis of the data, the statistical method of variance analysis of repeated measures was used.
Findings: In the intra-group comparison, a significant effect on performance was observed in both traditional and TRX training groups, but no significant difference was observed in the control group. The findings showed that, in the intergroup comparison between the intervention groups compared to the control and between the two intervention groups, a significant difference was observed in the performance and endurance variables of the trunk muscles, so that the TRX training group had a greater effect and effect size than the traditional training. .
Conclusion: In general, the results of this research showed that the TRX training program has a significant effect on improving performance compared to traditional resistance training.

Abstract
Background: GDNF protein that is effective in neurocognitive plasticity and sarcopenia, increases with resistance training. The aim of the research is the effect of six weeks of TRX training on the GDNF protein level in the serum of elderly women.
Materials and methods: The purpose of the research is applied with a semi-experimental method including pre-test-post-test with control group.28 elderly women from retirement center of Teacher Training University,Shahid Rajaei, were randomly assigned to the experimental group (n=15) with an average age of 60.86±5.60,BMI 27.65±4.22 ,control group (n=13) with an average age of 64.38±4.03,BMI 28.33 ± 2.18. In the first and last weeks, upper and lower body strength tests and GDNF protein levels were measured by ELISA kit .Shapiro-Wilk test for normality of data distribution,Levin test for homogeneity of variances,one-way analysis of covariance test (P<0.05) were performed to test hypotheses with spss24 software.
Results: Covariance analysis of upper and lower body strength were significantly different between groups (P<0.05).In adjusted averages,the GDNF protein level in the experimental group (443.102±15.751) is significantly higher than the control group (209.756±17.029)(P<0.05).
Conclusion: Six weeks of TRX training had a significant effect on the amount of GDNF protein, upper and lower body strength of elderly women, and can probably be effective in reducing or delaying sarcopenia.
