title: CONCURRENT VALIDITY OF INSTRUMENTS FOR MEASURING SPEED OF MOVEMENT IN LEG PRESS EXERCISES

description: ABSTRACT Introduction Adequate measurement of movement velocity in strength exercises can assist in the prescription and evaluation of training effects. Objective The objectives of the present study were to analyze the reliability (test-retest) and concurrent validity of the movement velocity measured by means of the electrogoniometer and accelerometer during horizontal leg press exercise at different intensities (40, 60, 80% of a maximum repetition - 1RM). Methods Eighteen young women attended the laboratory on five occasions. After determining the maximum dynamic force, two visits (separated by 48-72 hours) were used to verify the reliability (test-retest) for different speed variables in the three intensities. Results The mean propulsive velocity obtained by the goniometer showed higher Intraclass correlation coefficients (ICC) and lower coefficients of variation compared to the accelerometer. The same behavior was observed for both the mean velocity and the peak velocity. The propulsive time was more reproducible and with less variation for the accelerometer and bad CCI for both sensors were observed at 60% of 1RM. When the sensors are compared, the mean and average propulsive velocities presented moderate ratios with a large to very large standardized medium bias. Conclusion The potentiometer of the electrogoniometer can be used to estimate the velocity in the horizontal leg press exercise, especially for loads of 60 and 80%. The performance of the accelerometer was inferior to that of the potentiometer. Level of evidence II; Diagnostic studies.

title: SPORTS PARTICIPATION ASSOCIATED WITH HEALTH RISK BEHAVIORS IN ADOLESCENT ATHLETES

description: ABSTRACT Introduction Participation in structured sports activities is essential for the health of adolescents, since adolescence is a period in which several physical, psychological, cognitive and social changes occur, where the sense of autonomy in decision-making may prompt them to adhere to certain health risk behaviors. Objective To verify the association of sports participation with health risk behaviors in adolescent athletes. Methods A cross-sectional study with 367 athletes (15.68 ± 0.78 years) from Curitiba/PR (state of Paraná). Associated factors and health risk behaviors (HRB) were assessed using questionnaires. Poisson regression with robust variance was used to analyze factors associated with HRB, adopting p &lt;0.05. Results Team sport was positively associated with longer TV viewing time (PR: 3.11; 95% CI: 1.13-8.58). Years of participation were positively associated with longer TV viewing (PR: 1.14, 95% CI: 1.01-1.29) and video game playing time (PR: 1.12, 95% CI: 1.01-1.25). Negative associations were found for weekly training volume in longer video game playing time (OR: 0.92, 95% CI: 0.86-0.99), low vegetable consumption (PR: 0.98, 95% CI: 0.96-0.99), and in light (PR: 0.95, 95%CI: 0.92-0.99) and excessive (PR: 0.94, 95%CI: 0.89-0.99) alcoholic consumption. Conclusion The weekly training volume favors a reduction in video game playing time, lower alcohol consumption, and increased vegetable consumption in adolescent athletes.

title: THE EFFECT OF COLD WATER IMMERSION ON PAIN, MUSCLE RECRUITMENT AND POSTURAL CONTROL IN ATHLETES

description: ABSTRACT Introduction Numerous recovery strategies have been used to minimize performance loss related to delayed onset muscle soreness in athletes, and are part of prevention programs and training of most high-level sports. Objective To analyze the effects of cold-water immersion on delayed-onset muscle soreness, muscle recruitment, and postural control in soccer players. Objective The maximum load of the quadriceps femoris muscle strength was determined. After three days, the pain scale was used to measure the subject’s pain intensity. The recruitment of the quadriceps muscle was determined at the moment of the kick, and was associated with postural control. Methods Randomized, blinded clinical trial study. Two repeated series of maximum load sets at 60% MVC, performed in a knee extension chair, were used to induce quadriceps fatigue in the athletes. Participants Twenty-eight soccer players were allocated to four intervention groups: cold water immersion (CWIG, n = 7), thermoneutral water immersion (TWIG, n = 7), active recovery (ARG, n = 7), and rest (RG, n = 7), with each intervention being carried out for ten minutes. Revaluations were carried out after 24, 48, and 72 hours of the fatigue protocol. Results Pain intensity in the CWIG returned to baseline after 72 hours, while the TWIG, ARG, and RG continued to feel greater pain. For the other outcomes, no differences were found between the groups. Conclusion With regard to muscle recruitment and postural control at the time of the kick, no significant differences were found for the time periods or intervention established. Level of evidence I; High-quality randomized clinical trial with or without statistically significant difference, but with narrow confidence intervals.

title: THE USE OF PROPRIOCEPTIVE NEUROMUSCULAR FACILITATION FOR INCREASING THROWING PERFORMANCE

description: ABSTRACT Introduction Throwing is considered the most important technical skill in Handball. However, it requires the athlete to perform this movement with maximum speed and accuracy, as it can define the final score of the game. Objective The aim of this study was to evaluate the effect of Proprioceptive Neuromuscular Facilitation, known as the Kabat method, on the throwing performance of handball athletes. Methods An experimental study of 18 male handball athletes with a mean age of 14 ± 1.13 years. The athletes were divided into two groups: control group (CG) and Kabat method group (KG). The athletes performed 16 training sessions, with analyses at the beginning and end of each session. Range of motion (ROM) of internal and external shoulder rotation, strength, muscle imbalance, throwing speed and accuracy were measured. The results were compared by the Student t-test of repeated measures. Results KG significantly increased external shoulder rotation and muscle strength in all the analyzed shoulder complex muscles. CG also increased strength, but not in all muscles. KG significantly increased the speed and accuracy of the pitch. Conclusion The Kabat method, through proprioceptive neuromuscular facilitation, significantly increased throwing performance, speed and accuracy in handball athletes when compared to the control group. Level of evidence III; Randomized Experimental Study.

title: SEATED VOLLEYBALL: THE INFLUENCE OF MOTOR DEFICIENCY TYPE ON PLAYERS’ TACTICAL ROLES

description: ABSTRACT Introduction Sitting volleyball is an adapted sport played by players in the seated position, due to impaired mobility or amputations. Court dimensions are adjusted to the players’ average height, and during the games, the actions performed are similar to those of traditional volleyball. Objective To analyze the tactical performance of lower limb amputees and physically disabled athletes during seated volleyball games. Methods Data were collected from video footage, by a single observer, of twelve games of the Brazilian north-northeast championship 2017. The analysis investigated: i) average length of rallies; ii) frequency of attack actions; iii) game actions by amputation type; iv) outcomes of the actions by amputation type; v) direction and frequency of movements by disability. Results The average duration was 70 rallies per game, with the minimum disabled athletes performing the highest number of attack actions (43). Transfemoral amputees performed the highest number of blocking actions per game (10.5, in average). Conclusion Sitting volleyball has characteristics that are determined mainly by the type of disability. Players with minimal disabilities perform more attack actions and have higher performance per action, while amputees perform actions closer to the net, such as blocking and blocking points. The results also suggest that the type of amputation influences the direction of movement. Level of evidence II; Study Prospective.

title: BRADYCARDIA IN ATHLETES: DOES THE TYPE OF SPORT MAKE ANY DIFFERENCE? – A SYSTEMATIC REVIEW

description: ABSTRACT Bradycardia in athletes can range from moderate to severe, and the factors that contribute to slow heart rate are complex. Studies investigating the mechanisms associated with this condition are controversial, and may be linked to the form of exercise practiced. A systematic literature review was conducted to discuss bradycardia mechanisms in athletes who practice different forms of sport. The databases consulted were Pubmed (MEDLINE), Clinical Trials, Cochrane, Scopus, Web of Science, SciELO, Sport Discus and PEDro. The search included English language articles published up to January 2019, that evaluated athletes who practiced different forms of sport. One hundred and ninety-three articles were found, ten of which met the inclusion criteria, with 1549 male and female athletes who practiced diverse forms of sport. Resting heart rate and cardiac structure were studied in association with the form of sport practiced, through heart rate variability, electrocardiogram, echocardiogram and pharmacological blockade. The studies suggest that a slow resting heart rate cannot be explained by increased vagal modulation alone, but also includes changes in cardiac structure. According to the studies, different sports seem to produce different cardiac responses, and the bradycardia found in athletes can be explained by non-autonomic and autonomic mechanisms, depending on the type of effort or the form of sport practiced. However, the mechanism underlying the slow heart rate in each form of sport is still unclear. Level of evidence II; Prognostic studies - Investigating the effect of a patient characteristic on the outcome of disease.

title: ANTHROPOMETRIC FACTORS AND BODY COMPOSITION AND THEIR RELATIONSHIP WITH DYNAMIC BALANCE TESTS

description: ABSTRACT Introduction: The limit of stability is characterized by the maximum angle of inclination that an individual can reach and greater variability in extreme conditions; it is a bold and/or dangerous motor control strategy. Objective: Assess whether anthropometric measurements and body composition interfere with limits of stability and weight-bearing at different speeds in adults. Methods: Eighty-seven subjects of both sexes aged between 20 and 40 years were analyzed using anthropometric assessment and body composition. A force platform, limits of stability (LoS) and rhythmic weight shift (RWS) tests were used for the balance assessments. Results: In the LoS test, being female was negatively correlated with foot size and reaction time, and positively correlated with maximum excursion. In the RWS test, the female group had a negative correlation with height and upper limb length (ULL), with mediolateral directional control. The male group had a negative correlation with ULL and laterolateral directional control. Conclusion: Body composition variables do not interfere in the LoS and RWS tests in subjects with normal body mass index (BMI) values, except for bone densitometry (BMD) in women. As regards anthropometric parameters, height, ULL and foot size in the female and male groups were as follows: ULL and foot size exert little influence on postural balance control.

title: NEW RECREATIONAL CATEGORY ASSOCIATED WITH COMMON WART TRANSMISSION

description: ABSTRACT Introduction “Altinha”, a variant of beach soccer that is very popular on the beaches of Rio de Janeiro, is a recreational activity that adapts the basics of beach soccer to a game with a circular formation, with the participation of several players who mainly use the following parts of their bodies: feet, legs, head, knees and trunk. Since it is a Brazilian pursuit, the relationship between “altinha” and skin infections is poorly described. The authors report six cases of patients diagnosed with common warts, seeking to correlate the development of these lesions with participation in “altinha”. Clinical Case Six patients, young adults from Rio de Janeiro who play “altinha” on Rio’s beaches, with complaints of painless verrucous lesions, were assessed. Physical examination revealed cracked normochromic keratotic papules mainly affecting feet and legs of the dominant limb. In light of the medical history and physical examination, the diagnosis was of vulgar warts. The patients were treated with cryosurgery, obtaining satisfactory results. Discussion The sport and its outdoor environmental conditions favor transmission of the human papillomavirus due to exposure to factors such as humidity, sweating and trauma, besides direct contact with the infected skin of other players and with colonized surfaces. “Altinha” is played barefoot, and the equipment of choice is the soccer ball, which is constantly shared between players, leading to trauma caused not only by the ball, but also by the sand. Moreover, the activity demands physical exertion from participants, resulting in sweating and potential physical contact. Conclusion With the increasing popularity of “altinha” among beachgoers, dermatologists must be aware of the sun protection habits of these individuals. They must also be mindful of the need to examine their skin for related dermatosis and to warn them of the risk of infection by the human papillomavirus in this new sport.
