title: PROFILE OF INJURIES IN PARAGLIDING PILOTS IN BRAZIL AND THEIR RISK FACTORS

description: ABSTRACT Introduction: Paragliding is a free-flight activity that uses a flexible ultralight glider for takeoff, flight and landing. Despite the increasing number of practitioners of this sport in Brazil, no epidemiological data on paragliding injuries were found in the country. Objective: This study aimed to analyze the incidence, type, anatomical area affected, severity, and to verify if there is any pattern in the lesions in paraglider pilots in Brazil. Methods: A Quantitative, descriptive, analytical, cross-sectional, retrospective study was carried out using an adapted questionnaire from the Accident Notification Form of the German agency LBA - Federal Office of Civil Aeronautics to obtain information relevant to the research objectives. The application of the questionnaire was conducted online, through Google Forms Results: There were 575 valid participations, of which 92.7% were male, and 30.4% were between 41 and 50 years old. Among them, 68.6% reported having already had an injury in this sport. The anatomical region with the highest injury incidence was the lower limbs (44.09%), the landing being the flight phase in which most of the lesions occurred (68.01%). A logistic regression identified that “age” and “type of homologation” were the two factors associated with the occurrence of injury in the studied sample. Conclusion: Based on this research, it is possible to develop a functional training program for the practitioners of this modality, aiming at a better performance, measures of prevention of injuries associated to the sport, as well as to provide adequate rehabilitation to paragliding pilots.

title: SIX-MINUTE WALK TEST: PERFORMANCE OF OVERWEIGHT CHILDREN

description: ABSTRACT Introduction: The six-minute walk test (6MWT) has been used to evaluate exercise functional capacity in children. Objective: To compare the performance in six-minute walk test in schoolchildren aged 8 to 10 years, according to nutritional classification based on two different criteria. Methods: The sample of 226 children aged 8 to 10 years was divided into three groups (eutrophic, overweight, and obese), according to the criteria of nutritional classification proposed by the World Health Organization (WHO) and by the International Obesity Task Force (IOTF) and assessed by the six-minute walk test. Results: The prevalence of overweight and obesity in the sample was 42.48% according to the WHO criteria and 38.94% according to the IOTF criteria. There were no statistically significant differences between the groups eutrophic, overweight, and obese, when the results of the 6MWT were compared, both in the distance covered and in the percentage predicted for children, according to the reference values, and according to the two criteria of nutritional classification. The final heart rate of the test was statistically higher in the overweight or obese groups, both by the WHO criteria (p=0.0015) and by the IOTF criteria (p=0.0160) . Conclusions: In the studied sample, there was no difference in the performance of the 6MWT among eutrophic, overweight, and obese children. However, the final heart rate test was significantly higher among overweight children. The results emphasize that prevention, monitoring and treatment measures are necessary, promoting healthy habits.

title: EFFECTS OF PHYSICAL TRAINING ON THE MYOCARDIUM OF FEMALE LDL KNOCKOUT OVARIECTOMIZED MICE

description: ABSTRACT Introduction: The emergence of coronary heart disease increases with menopause, physical inactivity and with dyslipidemia. It is known that physical training promotes the improvement of cardiovascular functions. Objective: The purpose of this study was to investigate the effects of aerobic physical training on the left ventricle in female LDL knockout ovariectomized mice. Methods: Thirty animals were divided into 6 groups (n=5), namely, sedentary non-ovariectomized control; sedentary ovariectomized control; trained ovariectomized control; sedentary non-ovariectomized; sedentary ovariectomized; and trained ovariectomized. We analyzed the mean nuclear volume parameters, the cross sectional area of the myocytes, the apparent density of the capillaries, interstitium, myocytes and collagen fibers. Results: The results show that for the density of the number of nuclei, the physical activity decreased to values close to the ovariectomized control group. Regarding the mean nuclear volume and the average area of myocytes, training and ovariectomy promoted the elevation of these values but hypercholesterolemia was lower. the volume density of myocytes, hypercholesterolemia showed an increase of these values as well as the training. There was no change in the volumetric density of the capillaries and the density of collagen fibers. The training caused the decrease in the density of the interstitial volume, and the hypercholesterolemia changed to a smaller one than the control group. Conclusion: We concluded that the moderate aerobic activity or the training time used in our study were not sufficient to generate significant alterations in the hypercholesterolemic group.

title: A DYNAMIC RESISTANCE EXERCISE SESSION DOES NOT INDUCE POST-EXERCISE HYPOTENSION IN FEMALE SHR RATS

description: ABSTRACT Introduction: Dynamic resistance exercise has been recommended as an aerobic complement in hypertensive individuals. However, few studies evaluated the effects of resistance exercise in this population, especially in women. Objective: To evaluate the effects of a session of dynamic resistance exercise on blood pressure, heart rate and the double product in SHR female rats with spontaneous hypertension. Methods: We used 8 female SHR rats in the non-ovulatory phases of estrous cycle. Two days after the carotid artery cannulation, blood pressure was recorded for 20 minutes at baseline and for 60 minutes (5 min.; 15-30 min.; 30-45 min. and 45-60min.) after one session of dynamic resistance exercise in a ladder (20-40% of maximum load). Results: There were no changes in systolic blood pressure (baseline: 191±6.1 vs. recovery 45-60min., 191±7.8 mmHg), diastolic (baseline: 157±2.6 vs. recovery 45-60min., 156±3.7 mmHg) and mean blood pressure (baseline: 174±2.5 vs. recovery 45-60min., 173±4.9 mmHg) during the 60 minutes post-exercise. However, there was a reduction in heart rate (45-60min. 330±10 vs. 379±15 bpm) and normalization of the double product (64390±3529 mmHg.bpm) in the recovery period compared to the baseline. Conclusion: The results of the present study demonstrated that moderate-intensity dynamic resistance exercise induces reduced heart rate associated with normalization of the double product in female SHR rats, despite the absence of post-exercise hypotension. These results suggest good control of cardiovascular risk after a dynamic resistance exercise of moderate intensity in hypertensive patients.

title: EFFECT OF “FIFA 11+” ON THE PATTERN OF FUNDAMENTAL MOVEMENTS IN UNDER-14 SOCCER PLAYERS

description: ABSTRACT Introduction: Increasing youth participation in soccer has several benefits, but it also brings risks of injury. The use of neuromuscular techniques is effective in preventing injuries, especially in periods of growth as occurs in puberty, which coincides with the development of fundamental basic movements. Therefore, it is important to implement and evaluate prevention programs that focus on neuromuscular control during this stage. Objective: To determine the effect of the FIFA 11+ over a six-week training period in order to quickly improve fundamental movement patterns in under-14 soccer players. Method: A quasi-experimental study that evaluated the fundamental movement patterns through the Functional Movement Screen (FMS) in 22 athletes who were divided into a control group (CG; N=11) and an experimental group (EG; N=11), submitted to the program FIFA 11+ for six weeks. The SPSS 20.0 program was used to analyze the data. Results: Statistically significant improvements were found in the in-line lunge (IL) and in the post-intervention FMS total scores in EG, as well as intergroup improvements when testing the deep squat (DS) in the EG, but not in both groups. Conclusions: The six week FIFA 11+ program did not produce significant improvements in players’ fundamental movements.

title: THE DIFFERENT PHASES OF THE MENSTRUAL CYCLE DO NOT INFLUENCE THE PERFORMANCE OF SYNCHRONIZED SWIMMING ATHLETES

description: ABSTRACT Introduction: Knowledge regarding the influence of the phases of the menstrual cycle on the performance is still inconclusive. Objective: To analyze the physical and technical performance of synchronized swimmers in three different phases of the menstrual cycle. Methods: Six athletes of national level (age: 17.6±6.15) with normal menstrual cycle were evaluated considering the following phases of the menstrual cycle, namely, follicular (F), ovulatory (O) and luteal (L). Anthropometric, and neuromotor parameters, vertical displacement, eggbeater kick and performance in the technical routine were evaluated. Results: No changes were found in the anthropometric parameters, strength of the upper limbs (F; O; L); abdominal (F; O; L) and flexibility (F; O; L). In the specific tests, vertical displacement, eggbeater kick (F; O; L), and technical performance (F: 77±4; O: 80±5; L: 77±4 points) did not change throughout the menstrual cycle. Conclusion: The data of the present study indicate that the phases of the menstrual cycle do not directly influence the performance of synchronized swimming athletes.

title: ASSOCIATION OF ACTN3 R577X AND ACE I/D POLYMORPHISMS IN BRAZILIANS WRESTLERS

description: ABSTRACT Introduction: By associating genetics and sport, it is possible to identify subjects with greater capacity to adapt to training, and lower chances of injury. Objective: The investigation evaluated the genotypic and allelic distribution of ACTN3 R577X and ACE I/D polymorphisms in Brazilian high-performance athletes in wrestling and percussion combat sports. Methods: The study included 37 male athletes ranked from first to third place in world scenarios, divided into two groups: wrestling (23 wrestlers, being 11 of Judo, 4 of Greco-Roman style, 8 of Brazilian Jiu Jitsu, with mean age of 27.3 ± 6.9 years) and percussion combat sports (14 athletes with a mean age of 25.7±4.4 years, being 6 of Karate, 3 of Muay Thai, 4 of Taekwondo, 1 Boxing). Genotyping of ACTN3 and ACE I/D polymorphisms was performed by polymerase chain reaction (PCR) from the genomic DNA. Genotypic and allelic distributions were compared with control populations and athletes by Chi-square test and Fisher’s exact test; all analyzes considered p ≤ 0.05. Results: The genotypic distributions and allelic frequencies of ACTN3 RR=46%, RX=38% and XX=16%; R=65% and X=35%, and ACE I/D DD=47.7%, ID=34.3% and II=20%; D=62.9% and I=37.1% did not differ from the control population; however, when compared with wrestling athletes a significant difference was observed. Conclusion: These results suggest an association of ACTN3 R577X and ACE I/D genes with Brazilian high-performance wrestling athletes.

title: TAEKWONDO ATHLETES HAVE BETTER POSTURAL CONTROL THAN HANDBALL AND AMERICAN FOOTBALL ATHLETES

description: ABSTRACT Introduction: Postural control is an important prerequisite for an athlete’s performance in sport. In addition, the postural control system contributes to injury prevention. Deficits in this system can lead to body instability and overload of musculoskeletal structures generating dysfunction and pain. Objectives: The purpose of this study was to evaluate postural control in three different sports modalities: taekwondo, handball, and American football. Methods: All athletes performed a one-legged stance/balance test on a force platform in the right and left lower limbs. Three tests of thirty seconds each were performed with eyes open. The mean of the three tests was used to measure the parameters of postural control, pressure center and velocity of anteroposterior and mediolateral displacements. Results: Significant differences were observed among the three groups in all analyzed parameters (P=&lt;0.04). Post-hoc analysis revealed that taekwondo athletes had better postural control (P=&lt;0.035) of lower limbs compared to the other two modalities. There were no significant differences between handball and American football. Conclusion: Taekwondo athletes have better postural control during the one-legged stance/balance test than handball and American football athletes.
