بررسی نرخ شیوع و نواحی آناتومیکی آسیب های ورزشی در مردان والیبالیست حرفه ای شاغل در لیگ برتر ایران

Background and Objectives: Volleyball is a popular sport in society and despite its player’s low physical contact, the incidence of injury is very high. So in this study, researchers examined the incidence, severity and anatomical areas of sports injuries in men’s premier volleyball league of Iran. Materials and Methods: The study was performed on volleyball players of Iran’s premier league. Its population consisted the players of 12 teams in season 2019-20, and 120 athletes of them were selected as the subjects. The questionnaire of Australian Sports Medicine Pathology was used to record the subjects’ information. This study was a descriptive- field one; and its data was collected about the levels of incidence rate, severity and anatomical areas of injury. Results: The highest incidence rates of injury were related to ankle (26.5%) and shoulder (25.7%); and the highest injury type were related to inflammation and swelling (43.4%), spasm and muscle cramps (9.6%) and chronic tendon injury (8.1%). The intensity of injury was also highest in severe (49.3%), moderate (42.6%) and mild (8.1%), respectively. Conclusion: According to the results of this study, the incidence rate of severe injuries was very high and the ankle area had the highest incidence rate. These results are useful for accurate perception of injury process and preventive strategies for coaches and medical staff of professional volleyball teams.

The effects of six weeks of Core stabilization exercise on pain, Functional disability and Isometric strength of the trunk and lower extremities Muscle in women with patellofemoral pain syndrome

AbstractBackground and Aim:The knee joint is most common of region for injury and musculoskeletal disorders in lower extremity. Patellofemoral pain syndrome is as a common cause of knee pain in subjects. The purpose of present study was to assess the effect of core stabilization exercises on pain, functional disability andstrength of muscles of thelower Extremity and trunk in females with patellofemoral pain syndrome.Materials and Methods:Subjects in this study were 20 female with patellofemoral pain syndrome participated. The subjects were randomly divided into two groups. 10 Subjects in the experimental group (age 32.13±1.95 yr, height 169.00±7.59 cm, weight 65.50±6.80 kg) and 10 Subjects in the control group (age 31.25±1.58 yr, height 170.00±7.46 cm, weight 67.50±14.39 kg) participated in this study. Then experimental group performed exercises for 6 weeks. The Visual Analogue Scale (VAS) and Western Ontario and McMaster Universities (WOMAC) questioners were used to measure rate of functional disability and pain pre and post six weeks in both groups. also was used the dynamometer for measure isometric strength pre and post six weeks. Data using descriptive and inferential statistics (independent t test to compare scores at pre-test and post hoc t test to compare pre- and post-test scores) were analyzed.Results:The results showed that Core stabilization exercises has a significant effect on pain reduction in experimental compared with control group (p= 0.003). The mean score of disability test also showed significant improvement in experimental compared with control group (p= 0.001). Also, the results showed that Isometric strenghtening trunk flexor (p= 0.005) and extensor (p= 0.036), hip flexor (p= 0.001) and extensor (p= 0.001), hip abductor (p= 0.001) external rotator (p= 0.019), knee flexor (p= 0.001) and extensor muscles (p= 0.001) improved significantly compared with control group.Conclusion:According to results of this study, core stabilization exercises can reduce pain and improved disability and muscles isometric strength in subjects with patellofemoral pain syndrome. 

The Effectiveness of Schroth vs SEAS Exercise Methods for Correcting Idiopathic Scoliosis in Adolescents: A Systematic Review

Purpose: Adolescent Idiopathic Scoliosis (AIS) is the most common type of scoliosis and the most complex deformity of the spine. The promising results of Schroth and Scientific Exercise Approach to Scoliosis (SEAS), among other methods of exercise therapy, have attracted the attention of many researchers and therapists. However, there is still vague evidence of their effectiveness and their superiority. Therefore, this review aimed to evaluate and compare the effects of Schroth and SEAS exercises on correcting AIS. Methods: Searching was conducted in databases, including Cochrane, MEDLINE, PubMed, Scopus, and Google Scholar from 2005 to December 2021 using keywords related to AIS. Inclusion criteria were the papers using Schroth and SEAS exercises as an intervention. The PEDro scale was used for evaluating the quality of the papers. Results: Ten papers with an average PEDro score of 6.2 were licensed to enter the study. Five Randomized Controlled Trials (RCT) and one Clinical Controlled Trial (CCT) reported a significant reduction in Cobb Angle (CA) (greater than 5°) using the Schroth method (moderate). Moreover, two CCTs and one RCT indicated a significant reduction in CA (greater than 5°) using the SEAS method (limited). However, no paper was found for choosing superiority between Schroth and SEAS (no evidence). Conclusion: Although there is limited to moderate evidence in the studies, it seems that both Schroth and SEAS exercises were effective in improving AIS, which was more prominent in the study of the Schroth method. Nevertheless, accessing high-quality papers is necessary for achieving more accurate results in the future

The effect of the '11+ Kids' program on the isokinetic strength of young football players

Purpose: The "11+ Kids" injury-prevention program has been shown to reduce injuries and related costs in youth football players less than 14 y of age. A major argument to convince coaches to use this exercise-based injury-prevention program is a potential performance enhancement of the players. Therefore, this study investigated the effects of the "11+ Kids" program on isokinetic strength. Methods: Two teams were randomly assigned to the intervention and control groups. The intervention group replaced their warm-up by the "11+ Kids" and the control group warmed up as usual. Two days before and after the 10-wk intervention, isokinetic strength of the hip adductors and abductors, knee flexors and extensors, and ankle invertors and evertors was tested. Results: Thirty-one players (mean age 11.5 [0.8] y) completed the study. The intervention group showed large improvements in all isokinetic strength measures (P < .001 for all measures; Cohen d = 0.8-1.4), whereas the control group only showed negligible to medium positive effects (P values ranging from .006 to .718; Cohen d = -0.1 to 0.7). The intervention was beneficial compared with the control group regarding isokinetic strength of the hip adductors (P < .001), knee flexors (P = .002), and ankle evertors (P < .001) and invertors (P = .005). Conclusions: Given the relatively short intervention period of 10 wk, the observed improvements relate to a practically meaningful effect of the intervention. The gain in strength may improve players' performance and may contribute to a reduction of injury risk in the long-term application
