The Effect Of Eight Weeks Circuit Resistance Training On Serum Levels BDNF And TNF-α In Sedentary Postmenopausal Women
Elham Shakoor, Sadegh Amani, Ahmad Ghasemian, Ahmad Mehrez,
Volume 23, Issue 30 (1-2026)
Abstract
Aim: Resistance exercises are suggested as a non-drug treatment to improve the complications of menopause (cognitive-nervous and inflammatory problems). The purpose of this study was to investigate the effect of eight weeks of Circuit resistance training on the serum levels of BDNF and TNF-α in sedentary postmenopausal women.
methods: In this semi-experimental research, 30 postmenopausal women (age 54±3 years, body mass index 27.6±1.97 kg/m2) living in Tehran were randomly selected and assigned to two groups, Circuit resistance training groups (n=15) and control groups (n=15). Circuit Resistance training was performed for eight weeks, three sessions per week including 12 stations for the whole body with an intensity of 40-75%, one maximum repetition in three sets with repetitions between 8-12. 24 hours before and after the intervention, fasting blood was taken to measure BDNF and TNF-a were performed. Repeated measures ANOVA statistical method was used to analyze the data.
Results: In the resistance training group, compared to the control group, there was a significant increase in the levels of BDNF (%13.99) and a significant decrease in the levels of TNF-a (%32.92) (P<0.05).
Conclusion: According to the present study, it seems that low-to-moderate Circuit resistance training with increased BDNF and decreased TNF-a was able to improve cognitive-neural and inflammatory factors in postmenopausal women.

The Effect Of 8 Weeks Of Yumi Ho Massage On The Forward Head Angle And Kyphosis Of 13-17-Year-Old Male Students

Volume 23, Issue 30 (1-2026)
Abstract
Aim: Upper cross syndrome leads to widespread changes such as head forward, increased cervical lordosis, back kyphosis, round shoulder. Correcting musculoskeletal abnormalities and providing appropriate activities and movements to eliminate such disabilities and inefficiencies is of particular importance. Therefore, the purpose of this research is to investigate the effect of massage therapy on upper cruciate syndrome in male students.
Methods: In this research, 30 students with upper cruciate syndrome were divided into 2 groups (massage group (15 people) - control group (15 people)). The amount of head forward was evaluated with a camera and back kyphosis was evaluated with a flexible ruler method, and then for 8 weeks of Yomi Ho therapy massage, SPSS version 24 software was used to analyze the data of this research.
Results: The results of multivariate and univariate covariance analysis showed that there is a significant difference between the two massage therapy groups and the control group in forward head (P<0.001) and kyphosis variables (P<0.001).
Conclusion: The results of the present study showed that Yumi Ho therapy massage is an effective method in improving upper cruciate syndrome and especially on forward head and kyphosis abnormalities.

 
The Effect Of Feedback Interventions On Lower Limb Mechanics And Performance In people With Motor Control Deficits In Jump-Landing Movements: a Systematic Review
Mohadeseh Ashrafizadeh, Ali Asghar Norasteh,
Volume 23, Issue 30 (1-2026)
Abstract
Introduction & Aim: Motor control deficits such as dynamic knee valgus and quadriceps dominance are recognized as key modifiable risk factors for lower-limb injuries. Feedback-based training has been proposed as an effective strategy to correct high-risk biomechanics. This systematic review aimed to investigate the effects of feedback interventions on lower-limb mechanics and performance during jump-landing movements
Methods: A comprehensive search was conducted in international databases (PubMed, Scopus, Science Direct, Google Scholar) and national databases (Magiran, Irandoc) from 2000 to 2023. Studies were included if they examined the effects of any form of feedback on healthy individuals with lower-limb motor control deficits. From an initial 540 retrieved articles, 20 studies met the inclusion criteria after screening and full-text review.
Results: Most studies reported that feedback, particularly external or real-time feedback, led to increased flexion angles of the hip and knee in the sagittal plane during jump-landing. The findings regarding frontal plane mechanics were inconsistent: some studies showed a reduction in knee valgus angle, while others reported no significant change. A majority confirmed a reduction in peak vertical ground reaction force following feedback. However, limited studies assessed performance outcomes such as jump height or reactive strength index, and their findings were contradictory.
Conclusion: Feedback interventions appear effective in improving biomechanical risk factors related to lower-limb injury during jump-landing tasks; however, their impact on functional performance remains unclear. Further research is required to determine long-term retention and performance outcomes.
