Case presentation: We report two cases of dog attacks in off-road cycling and discuss the basic principles in prevention and management of such incidents. The cyclists received all 5-dose regimen of the rabies vaccine and returned to sport after 6 weeks. During 6-month follow-up period, no complications were observed. Conclusions: To reduce the probability of dog attacks and its complications, the off-road cyclists should be familiar with some basic principles. They should also be educated about initial on-site management of the related injuries, which may have a great impact on decreasing further complications.

The purpose of study was to examine the effect of knee isokinetic extension in maximum lateral tibia rotation on VMO and VL amplitudes in PFPS patients. Materials & Methods Thirty-six women with PFPS participated voluntarily in this study and were randomly placed in one of three groups included the VMO selective isokinetic strengthening exercise, quadriceps general strengthening and control groups. Each exercise was performed for 8 weeks. Muscle RMS of VMO and VL and VMO/VL RMS ratio were recorded and calculated before and after training using of an 8-channels electromyography system. Data analysis was made by analyses of variance with repeated measures. Results In baseline, VMO amplitude was less than VL in all groups (P≤0.05), but after interventions, it was more than VL in selective group (P=0.01) and less than VL in general (P=0.001) and control (P=0.036) groups. Before interventions, there was no difference between groups in muscles amplitude (P>0.05). Yet, after interventions, VMO amplitude and VMO/VL amplitude ratio were more in selective group than in general and control groups (P≤0.001), and VL amplitude was more in general group than in selective and control groups (P≤0.01). Conclusion According to the study results, isokinetic extension training with maximum lateral tibia rotation and in close to knee full extension can be recommended as an appropriate training for improving VMO/VL electrical activity ratio and decreasing imbalance between lateral and medial vastus muscles amplitudes in patients with PFPS.

Ultramarathons have a wide spectrum of race characteristics from the variety of distances to environmental factors. Ultramarathons continue to attract a relatively small number of participants who on average are more experienced than marathon runners. There are limited epidemiologic studies on common ultramarathon injuries and illnesses. Musculoskeletal and dermatologic problems are very common among ultramarathoners. Each ultramarathon is unique, and medical directors should try to establish an injury surveillance system in order to be better prepared for possible medical conditions. The focus of this article is on the evaluation and management of common medical conditions encountered during ultramarathons.

Methods: From January to June 2009, 30 patients with basic diabetes education were followed for a period of 90 days. To provide assessment of glycemic control and frequency of dysglycemia, patients, underwent 3 consecutive days of seven-point SMBG during each month for 3 consecutive months, using the ACCU-CHEK 360° View tool. Glucose profiles of the first and third month were used for comparison. Results: Hemoglobin A1c (HbA1c) improved significantly during the 90-day period in all patients [confidence interval (CI) 95%, 0.32–1.64%, p < .05] and those with poor metabolic control (group B; CI 95%, 0.86–2.64%, p < .05). Mean blood glucose (MBG) values decreased significantly in group B (CI 95%, 0.56–24.78 mg/dl, p < .05) and all cases (CI 95%, 1.61–19....

Mountain Biking Injuries

Almost two thirds of acute injuries involve the upper extremities, and a similar proportion of overuse injuries affect the lower extremities. Mountain biking appears to be a high-risk sport for severe spine injuries. New trends of injury patterns are observed with popularity of mountain bike trail parks and freeride cycling. Using protective gear, improving technical proficiency, and physical fitness may somewhat decrease the risk of injuries. Simple modifications in bicycle-rider interface areas and with the bicycle (bike fit) also may decrease some overuse injuries. Bike fit provides the clinician with postural correction during the sport. In this review, we also discuss the importance of race-day management strategies and monitoring the injury trends.

In Iranian women with type II diabetes, we compared the effects of supervised group exercise therapy with the effects of home-based exercise therapy on health-related quality of life (HRQOL), anthropometric parameters, glycaemic control and lipid profile. One hundred and two diabetic women were randomised to supervised and home-based groups. Over 12 weeks, participants received supervised group-exercise therapy or a home-based exercise-therapy program. During the intervention, they were assessed three times: at baseline, and at weeks 6 and 12. Generalized Estimating Equation models were used to examine the associations between the type of exercise-therapy program and changes over time in anthropometric and biochemical outcomes, and in HRQOL scales of SF36 questionnaire. Relative to home-based group, supervised group improved significantly regarding role-physical, general health, mean body weight and body mass index from baseline to week 12 (p=0.01). Their reduction in mean body-fat mass from baseline to week 6 (p=0.04) was greater. Similarly, their role-physical, general health and role-emotional improved significantly during the intervention (p&amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.05). From baseline to the twelfth week, the HbA1c level fell significantly (p&amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.05) in both groups. Supervised group-exercise therapy was more effective than home-based exercise therapy in improving HRQOL and body composition in diabetic women. However, home-based exercise therapy also produced significant improvements in glycaemic control, body composition and lipid profile. Whether in a supervised or home-based setting, the exercise intervention can therefore be effective in improving health outcomes in diabetic patients.

We also aimed to compare the maximum isometric back strength and endurance, as well as flexibility of lower back in cyclists with LBP and in the controls.METHODS: The thickness of Transversus Abdominis (TrA), Internal Oblique (IO) and External Oblique (EO) along with the CSA of LM muscles of 14 professional competitive off-road cyclists with LBP and 24 controls were measured by ultrasound (US) in hook-lying position on the examination table, and mounted on the bicycle. In addition, the back strength and endurance of the subjects and the flexibility of the participants were measured.RESULTS: Data showed a significantly lower thickness of Transversus Abdominis (TrA) and CSA of LM muscles in cyclists with LBP comparing to controls in all positions. No significant result regarding the flexibil...

Ultrasonography is increasingly utilized to measure the thickness of these muscles. Prandial state has recently been proposed as a confounding factor in such measurements. We aimed to compare the reversal time of the postprandial thickness of these muscles with preprandial values. The measurement errors of ultrasonographic values were also assessed in both immediate preprandial and postprandial states. Interventional cross-sectional study. The ultrasonographic thickness of lateral abdominal muscles was measured at rest and during abdominal drawing-in maneuver in 20 healthy participants before and after consumption of a specific meal. Postprandial ultrasound measurements continued every 15 min until their thickness reached 95% of their preprandial values. There was a statistically significant reduction in postprandial thickness of these muscles (all p-values &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.001 on both sides). The reversal times were 1.5, 1.3 and 1.2 h for Transversus Abdominis, Internal Oblique, and External Oblique muscles, respectively. Standard Error of Measurement and Smallest Detectable Change were in the range of 0.007-0.013 mm and 0.020-0.035 mm, respectively. To limit the effects of prandial state on the sonographic thickness of lateral abdominal muscles, we recommend measuring these values at least 1.5-2 h after food consumption. For the future studies, controlling the participants according to their prandial state is recommended.
