Read More Manipulating resistance training program variables is a commonly used tool for optimizing maximum muscle strength in rehabilitation and/or exercise training programs. The current study purposed to compare the effects of 12 weeks of concentric and eccentric resistance training on neuromuscular adaptation of quadriceps muscle. Methods Twenty-six male subjects (age, mean ± SD, 22.1 ± 2.4 yr; body mass, 72.3 ± 9.9 kg; height, 1.75 ± 0.08 m) were recruited for this controlled laboratory study. Subjects were randomly divided into two groups: the eccentric training group (No = 13) and the concentric training group (No = 13). The maximal isometric voluntary contraction (MVIC) of quadriceps muscles, vertical jumping, and surface electromyography (EMG) signals were recorded before and after 12 weeks of resistance concentric and eccentric training. Repeated-measures Analysis of Variance (ANOVA) was used to test differences between means before and after resistance training. Results The maximal isometric voluntary contraction of the quadriceps muscle and vertical jumping were significantly increased after eccentric and concentric training (p <0.05). Eccentric exercise resulted in a greater increase in maximal isometric voluntary contraction of the quadriceps muscle and vertical jumping compared to concentric training (p <0.05). The amplitude of surface EMG signals was also significantly increased after eccentric and concentric training (p <0.05), with a greater increase observed in the eccentric than the concentric training group (p <0.05). Conclusion The results of this study showed higher increases in muscle force output and EMG activity after eccentric training. This may indicate that stretch combined with overloading is the most effective stimulus for enhancing neuromuscular activity during dynamic resistance exercise. The knowledge gained from this study may be relevant for designing exercise and/or rehabilitation training to improve muscle output.

Read More Background: Coronary Artery Bypass Grafting is an effective treatment for reducing symptoms and mortality in coronary artery patients.Although patients experience post sternotomy complications such as musculoskeletal disorders. So, the aim of this study was to compare the head, neck and upper trunk postures between patients who underwent coronary artery bypass grafting and healthy individuals. Methods: In this cross-sectional case-control study, twenty-one men (56.38 ± 8.64 years) were randomly selected from among patients who had been referred to Al-Zahra Cardiac Rehabilitation Center in Shiraz and undergone coronary artery bypass grafting (CABG), and the angles of forward head, thoracic kyphosis, and rounded shoulder were measured. Twenty healthy men (51.70 ± 10.40 years) were also evaluated and compared in terms of the above variables. This study was designed and conducted as a pilot. The angles of the forward head and rounded shoulder were assessed by placing reflective markers on the body and processing the images by Digimizer MedCalc software, version 4.6.1. Thoracic kyphosis angle was measured by a flexible ruler. The Persian version of the SF36 questionnaire was used to assess the quality of life, and the Kolmogorov-Smirnov test to verify the normal distribution of data. Independent sample t-test and Mann-Whitney test were used for between-group comparison for data with normal and non-normal distribution, respectively. Results: The comparison of the forward head, rounded shoulder, and thoracic kyphosis angles showed no significant difference between post-surgical and healthy subjects (P> 0.05). Patients' quality of life was significantly different from that of the control group in all aspects, except for general and mental-emotional health (p <0.05). Conclusion: There was no significant difference between the case and control groups in the angles of forward head, thoracic kyphosis, and rounded shoulder. Patients who underwent CABG, however, experienced a significant reduction in their quality of life compared to the control group. Therefore, it seems necessary to pay attention to patients and find solutions to manage and improve various aspects of life, such as physical and mental health.

Read More Background: Forward head posture is a major postural deformity in the head and neck area. Considering the importance and secondary consequences of this deformity, current study aims at investigating this deformity among boys and girls of different educational levels of Tehran universities. Methods: This is a cross-sectional descriptive and field study (causal-comparative). A total of 1017 students, 511 girls (age: 23.74±3.91, height: 162.42±7.14, weight: 57.33±8.87) and 506 boys (age: 23.82±3.57, height: 174.70±7.97, weight: 69.19±12.18) were selected. Their forward head angle was measured 3 times by a specific goniometer and the subjects' final angle was considered as the average of three measurements. Data were analyzed using SPSS V.22 software and the two-way ANOVA, Tukey and one-way ANOVA tests. Results: The results of one-way ANOVA analysis showed a significant difference in the head angle of the students at different educational levels (p <0.05). The results of Tukey post-hoc test showed a significant difference between post-graduate and undergraduate female students and doctoral female students (p <0.05). Also, there was a significant difference only between male undergraduate students and male doctoral students (p <0.05). The results of two-way ANOVA showed that gender and educational level factors had a significant effect on head angle (p <0.05), but neither factor had an interaction effect on head angle (P>0.05). Conclusion: According to the results of this study, educational level and gender were the major factors in the development of forward head posture, so considering these two variables could be effective in prevention, control, and correction of related deformities. Background: Forward head posture is a major postural deformity in the head and neck area. Considering the importance and secondary consequences of this deformity, current study aims at investigating this deformity among boys and girls of different educational levels of Tehran universities.
