Objective :

Movement pattern correction exercises using TRX are a novel approach that has recently attracted the attention of researchers. Therefore, the purpose of this research is to investigate the effect of movement pattern correction exercises using TRX on the landing biomechanics and balance of female volleyball players prone to knee injuries.

Methods :

Twenty female volleyball players prone to knee injuries were selected based on specific criteria and split into two groups: one practiced TRX-based movement correcti:on exercises, while the other served as the control. Initial assessments included anthropometric measurements, static/dynamic balance, and landing biomechanics using various tests. The training group underwent exercises three times a week for six weeks, while the control refrained from impactful sports activities. All participants continued their volleyball routines. Post-training, the same assessments were conducted, and statistical analyses were performed using paired t-tests and analysis of covariance to evaluate the results.

Results :

The paired t-test results showed that the static and dynamic balance and landing mechanics of the subjects in the experimental group improved significantly in the post-test stage compared to the pre-test (p < 0.05), while there was no significant difference in the investigated variables in the control group (p ≤ 0.05). Additionally, the results of the analysis of covariance showed a significant difference in the scores of the balance and landing error variables between the two groups in the post-test phase (p < 0.05)..

Conclusion:

 Improving balance and increasing a person's ability to control the movements of the trunk and knee joint during landing can probably occur due to the improvement in the performance of the core stabilizer muscles of the body. Therefore, the use of movement pattern correction exercises using TRX can be considered an effective approach to prevent knee injuries in susceptible female volleyball players.

Introduction and One of the common signs of old age is a 2-4 times increase in the levels of pro-inflammatory cytokines. The aim of this study was to investigate the effect of a course of TRX exercises on cardiovascular parameters PTX3, CRP, IL-18 in overweight elderly men. In this semi-experimental study, 30 overweight elderly men participated and were randomly divided into two TRX training groups (15 people) and control (15 people). The experimental group performed exercises for 12 weeks and 3 sessions each week for 60 minutes (10 minutes of warm-up, 40 minutes of training and 10 minutes of cooling down). Blood samples were collected in two pre-test stages and 48 hours after the last training session to measure the serum levels of PTX3, CRP and IL-18. The data were analyzed using covariance and paired t test at a significant level of P≤0.05. TRX exercises caused a significant decrease in serum levels of PTX3, CRP, IL-18 in the post-test of the experimental group (P≤0.05).Discussion and It seems that this type of exercise can reduce inflammatory markers CRP and IL-18 in elderly people. These exercises are suggested as an effective factor in improving cardiovascular risk factors related to aging.

The aim of this study was to investigate the effect of selected TRX exercises on functional stability,proprioception and strength of shoulder joint muscles in athletes with scapular dyskinesis.The present study is a semi-experimental study with pre-test and post-test design.For this purpose,30 male athletes of overhead athletes with scapular dyskinesis were randomly divided into training and control 15 person in each group.Athletes with scapular dyskinesis were identified using a lateral scapular slide test.In the pre-test, the strength of internal and external rotator cuff muscles,functional stability and accuracy of shoulder joint proprioception were evaluated by manual dynamometer tests,upper body functional balance test and imaging method, respectively.The subjects in the training group then performed the selected TRX exercises for 8 weeks and 3 sessions per week.At the end of 8 weeks,all measurements of the pre-test were performed again in the post-test stage.A Two-way analysis of variance was used to statistically analyze the research findings at a significance level of P≤0.05.The results of two-way analysis of variance showed that in the post-test stage, rotational muscle strength(P=0.001),functional stability(P=0.001) and accuracy of shoulder joint proprioception(P=0.001) of the experimental group significantly improved compared to the control group.According to the results of the study, it is According to the improvement in rotational muscle strength, functional stability and accuracy of shoulder joint proprioception in TRX group,it is suggested that the TRX exercises used in the present study can use to improve the disorders caused by scapular dyskinesia in overhead athletes and to prevent possible injuries to the shoulder joint.
