The aim of this study was to determine the prevalence, magnitude, and methods of rapid weight loss (RWL) in visually impaired (VI) judo athletes, and compare these aspects between males and females. Thirty VI judo athletes (20 men and 10 women) completed a validated questionnaire to assess information about the magnitude and methods of RWL. Simple frequency was used to describe the influence and methods in all athletes and according to sex. Moreover, the t test was used to compare the variables between the sexes with the significance level set at p < .05. The main results showed that most VI judo athletes (67%) lost weight to compete. Most methods included gradual dieting (40%) and increased exercise volume (33%). The judo coach/ sensei was the person who most influenced the athletes in RWL (45%). There were no significant differences between the sexes regarding the RWL magnitude and methods used. As concluded, most VI judo athletes lost weight to compete, but the interval to reduce weight seemed slightly longer than it usually occurs in RWL. Gradual dieting and increased exercise volume were the most frequently used methods to lose weight, without any differences between males and females.

American football is a high-impact collision sport, which may lead to high injury rates in the players. thus, knowing the aetiology and incidence of injuries may be useful not only for the treatment, but especially to help sports professionals to develop strategies or mechanisms of prevention while aiming to maintain the physical integrity of the athletes. Purpose. the aim of the study was to verify the prevalence of injury among American football players from the Santa Catarina state of Brazil. Methods. the total of 140 athletes were evaluated in the study with the use of an online questionnaire. Descriptive logistic regression and t-test analysis were applied (p < 0.05). Results. A high injury prevalence (74%) in the evaluated athletes was observed. Most of these injuries occurred during training (56%) and by direct contact between players (64%). Shoulders, knees, and hand/fingers were the most commonly injured body parts (14%, 13%, 12%, respectively). the most frequent types of injuries were those related to joints (46%) and muscles (39%), and very few concussions were reported. We found a significant positive association showing that the athletes that performed a conditioning program presented higher injury prevalence (p = 0.01). Conclusions. American football players of the Santa Catarina state are affected by high injury prevalence. the training characteristics, in general, do not seem to be associated with injury prevalence. thus, aiming to reduce the exposure to injuries, we recommend for coaches and trainers to monitor the total volume of training and participation in matches.
