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
The researchers conducted the present study with the aim of investigating the pain and muscle disorders of patients with covid-19 with people who have experienced it. The research was applied and comparative. Samples were calculated using G-power of 303 people, and sports teachers were excluded from the research. The Nordic questionnaire was provided to Ardabil education and training employees after the investigation, the number of people with one year of identification and the number of 113 people with the age range of 30 to 45 years reported no reduction. Then, musculoskeletal disorders of 9 body areas in both groups were evaluated using descriptive statistics and chi-square test at a significance level of 0.01. The muscle pain of the affected group was significantly (P<0.01) higher than that of the healthy group, and also based on the chi-square test, the amount of back and neck pain was 52% and 45%, respectively, in affected people compared to other organs. It was more meaningful. (P<0.01) noticed that there was no significant difference between the pain and discomfort of different organs in the non-observed group. Corona patients may experience pain, and the cause of it in the Nordic questionnaire, in addition to physical abnormalities and excessive muscle disease, can be from Corona disease; Therefore, the Nordic questionnaire should be used.
