IntroductionAthletics is a sport with varied modalities, which are based on patterns and activities that are natural to human beings. As a sport, it has several benefits, such as improved physical condition and interpersonal interactions, but it is not free from risks, especially injuries related to competitions or training.ObjectivesCharacterize injuries presented by the university athletics group of the medical course and identify possible risk factors.MethodsParticipants, enrolled in the athletics group of the medicine course, of both sexes, had anthropometric measurements evaluated and answered an injury screening questionnaire modified from the “Injury Surveillance System”.Results31 participants responded to the questionnaire where 65% of them had at least one injury. A total of 23 injuries were reported, 20 of which were serious, with no significant difference between both sexes. The total practice time was almost 2 times longer in injured practitioners than in non-injured ones.ConclusionThe practice of university athletics is associated with a high occurrence of serious injuries.SUMMARY BOXCollege athletics appears to have a high incidence of injury.There is an unusually high number of serious injuries in college athletic athletes participating in the study.Most college athletic sports injuries do not appear to be diagnosed or properly treated.Most injuries are concentrated in the lower body.
Introduction: Many treatment modalities are used for muscle tissue recovery. Photobiomodulation is a modality that can be employed to improve the quality of tissue repair. The use of fractal dimension (FD) is an innovative methodology in the quantitative evaluation of treatment efficacy. Objective: Use FD as a quantitative analysis method to evaluate the effect of photobiomodulation of 904 nanometers (nm) in the initial phase of the muscle regeneration process. Method: Thirty male Wistar rats were divided into three groups: Control Group (CG), Injured and Untreated Group (IUT), and Injured and Treated Group (IT). Muscle injury was induced by cryoinjury in the central region of the anterior tibial (AT) belly of the left posterior limb. This was performed by an iron rod that was previously immersed in liquid nitrogen. Applications started 24 hours after the injury and occurred daily for five days. They were performed at two points in the lesion area. The rats were euthanized on the seventh day. The AT muscles were removed and frozen in liquid nitrogen. Then, the histological sections were stained using the Hematoxylin-Eosin (HE) technique and submitted to FD analysis performed by the box-counting method using ImageJ software. The Kolmogorov-Smirnov test was used for data normality, and the Kruskall-Wallis test and Dunn's post-test were used for group comparison (p<0.05%). Results: Differences between IT and IUT groups were statistically significant, and it was possible to observe the reduction of fractability with p=0.0034. Conclusion: FD is a useful tool for the analysis of skeletal muscle disorganization in the initial phase of regeneration and confirms the potentially beneficial effects of photobiomodulation to this process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
