Patellofemoral pain syndrome (PFPS) is a very common disorder of the knee. Due to multiple forces influencing the patellofemoral joint, clinical management of this ailment is particularly intricate. Patellofemoral pain syndrome has a multifactorial nature and multiple parameters have been proposed as potential risk factors, classified as intrinsic or extrinsic. Some of the intrinsic risk factors are modifiable and may be approached in treatment. A number of modifiable risk factors have been suggested, including quadriceps weakness, tightness of hamstring, iliopsoas and gastrosoleus muscles, hip muscles dysfunction, foot overpronation, tightness of iliotibial band, generalised joint laxity, limb length discrepancy, patellar malalignment and hypermobility. In general, the routine approach of physicians to this problem does not include assessment and modification of these risk factors and therefore, it may negatively affect the management outcomes. Changing this approach necessitates an easy and practical protocol for assessment of modifiable risk factors and effective and feasible measures to address them. In this review, we aimed to introduce assessment and intervention packages appropriate for this purpose.

This population-based, cross-sectional study aimed to determine the frequency of neck pain, low back pain (LBP) and also the LBP related functional disability in five sport categories including football, volleyball, basketball, wrestling, and other sports in one of the Iranian sport Olympiads. The prevalence of neck pain and LBP in different time points was evaluated with the use of an interview questionnaire. A visual analogue scale was used to evaluate the athlete’s current pain. Furthermore, the functional disability related to LBP was assessed by the Athletes Disability Index Questionnaire (ADI). A total of 452 male athletes aging between 12 and 20 were screened. Three hundred seventy-seven participants responded to the questionnaires in which their mean age (standard deviation) was 15.95 (1.25). Collectively, the life-time prevalence of neck pain and LBP in all the athletes was 38.8% and 42.0%, respectively. The highest risk of neck pain at all-time points was observed among basketball players compared to other sport groups (P<0.05). The risk of LBP in most time points was the least among wrestlers (P<0.05). The ADI score was significantly higher among basketball players (13.89%) compared to volleyball players and wrestlers (P<0.05). Our study revealed a high prevalence of neck pain and LBP among Iranian young male athletes. A higher risk of neck pain and LBP among basketball players predisposes this sport at high risk of developing spine injuries which needs further consideration.

Background: Soccer is the world's most popular sport, with most players being younger than 18 years. "FIFA 11+ Kids" has been recently introduced to prevent soccer injuries in adolescent players. This program would be more accepted and followed by coaches and players if it were to also promote performance and physical fitness in players. The purpose of this study was to assess the effect of a ten-week FIFA 11+ for kids Injury prevention program on performance and physical fitness in adolescent soccer players.

Purpose: Despite the acknowledged impact of imagery on performance, ecologically sound studies investigating imagery and its effects on performance subcomponents in real games are surprisingly limited. The aim of this study was to investigate the effects of imagery training on passing improvement in elite soccer players.Methods: Sixty nine soccer players taking part in the national championship leagues in four age categories including U16, U19, U21 and over 21 were randomly assigned to the imagery and control groups. Interventional group participants completed an 8 week video-aided, cognitive imagery program on how to make a perfect soccer pass.Results: Performance analysis through close video analysis showed that successful pass rate increased significantly in the intervention group compared to control (OR=1.19, P=0.002, 95% CI=1.06-1.33). Further analysis revealed that the results are statistically significant in U16 and U21 but not other categories. Conclusions:We concluded that successful soccer passing through real competitions as a multidimensional and critical open skill could be enhanced by an ecologically sound method of mental imagery.

Sudden cardiac death (SCD) in a young athlete is rare, but catastrophic. Exercise acts as a risk factor for SCD in people with cardiovascular disease. A diversity of cardiovascular disorders including hypertrophic cardiomyopathy, congenital coronary anomalies, arrhythmogenic right ventricular dysplasia, dilated cardiomyopathy, aortic rupture due to Marfan syndrome, myocarditis, valvular disease and electrical disorders (Wolff-Parkinson-White syndrome, long QT syndrome, Brugada syndrome), as well as commotio cordis represent the common causes of SCD in young athletes.As the outcome of lethal cardiovascular disorders is not reversible except in few cases, effective measures should be addressed to reduce the burden of sudden cardiac death in young athletes. Currently, two types of recommendations are proposed by American and European countries.It seems that there are some special considerations in Asia, entirely different from North America or Europe, which warrant more comprehensive research on epidemiology and etiology of SCD in young Asian athletes by country and evaluation of current national preventive strategies and their achievements in decreasing the risk. Using these data and considering regional restrictions, an expert group will be able to plan a practical and feasible preventive strategy.
