RESUMO

INTRODUCTION: Combat readiness assessments through simulated tasks (STs) have been developed for the Brazilian Air Force (BAF) to establish physical employment standards. Previous research has established BAF critical combat tasks with STs developed based on the physical demands of these tasks. Before implementing these STs, the standards required of BAF personnel must be established. The aim of this study was to determine the cut-off scores for five previously established STs. METHODS: Eighty-eight cadets attended three different testing batteries in order to complete the five STs, being: Battery 1 (foot march), Battery 2 (plane crash on water and water survival skills) and Battery 3 (plane crash on land, obstacle course) with their times recorded. Cut-off scores were set at the 85th percentile of the data distribution with these values and then analysed by four subject matter experts (SMEs) using subjective criteria through criterion analysis. RESULTS: All 88 cadets were submitted to the five assessments. After analysing the performance results on the STs, the SMEs discussed and agreed on the following cut-off scores: obstacle course (3:21 min:s), foot march (31:00 min:s), plane crash on land (1:25 min:s), plane crash on water (1:12 min:s) and water survival skills (4:03 min:s). CONCLUSION: The outcomes of this research allow for the five STs to be implemented in BAF cadets and qualified BAF personnel with the established cut-off scores used to monitor the operational capability of these personnel (be it for cadet training outcomes or unit preparedness assessments) and to guide conditioning practices if personnel are below standards.

RESUMO

Abstract Objective To investigate the epidemiology of injury types among jiu-jitsu practitioners, as well as the incidence regarding different skill and experience levels, through the question: "What are the characteristics and prevalence of musculoskeletal injuries in Jiu-Jitsu practitioners?". Methods Since the beginning of the study, in August 2020, we conducted a search on the MEDLINE, LILACS, and SciELO electronic databases. We included cross-sectional studies published between 2018 and 2023 on the epidemiology of the types of injuries among jiu-jitsu practitioners that compared their incidence regarding different levels of ability and experience. Two independent researchers performed the data extraction and assessed the risk of bias. Results Seven studies were included. The common outcomes involved 2,847 jiu-jitsu practitioners. A high prevalence in the knee joint and chest and rib areas was reported. Considering the difference in experience level among the practitioners, we could observe that most of the individuals included were beginners. Among the age groups observed, male practitioners older than 30 years of age were the ones who presented the highest rate of musculoskeletal injury, especially during training sessions. Conclusion There is a high prevalence of musculoskeletal injuries among jiu-jitsu practitioners. The most affected anatomical segments are the knee joint, the chest, and the rib region, followed by the shoulder joint. The related factors change according to certain variables, being more common during training in male individuals over 30 years of age and beginners in the sport.

Resumo Objetivo Investigar a epidemiologia dos tipos de lesões entre praticantes de jiu-jitsu e sua incidência em diferentes níveis de habilidade e experiência por meio da questão: "Quais as características e a prevalência das lesões musculoesqueléticas em praticantes de jiu-jitsu?" Métodos Desde o início do estudo, em agosto de 2020, foram pesquisados os bancos de dados MEDLINE, LILACS e SciELO. Foram incluídos estudos transversais, publicados entre 2018 e 2023, que investigaram a epidemiologia dos tipos de lesões ocorridas entre praticantes de jiu-jitsu e compararam sua incidência em diferentes níveis de habilidade e experiência. Para tanto, dois pesquisadores independentes realizaram a extração dos dados e avaliaram o risco de viés. Resultados Sete estudos foram incluídos. Os resultados comuns envolveram 2.847 praticantes de jiu-jitsu. Houve uma alta prevalência de lesão na articulação do joelho e nas áreas do tórax e das costelas. Considerando a diferença de nível de experiência entre os praticantes, pôde-se observar que a maioria dos indivíduos incluídos eram iniciantes. Entre as faixas etárias observadas, homens acima de 30 anos de idade foram os que mais apresentaram lesões musculoesqueléticas, principalmente durante os treinos. Conclusão Houve uma alta prevalência de lesões musculoesqueléticas entre os praticantes de jiu-jitsu. Os segmentos anatômicos mais acometidos foram a articulação do joelho, o tórax e a região das costelas, seguidos da articulação do ombro. Os fatores relacionados mudaram de acordo com algumas variáveis, sendo mais comuns durante o treinamento em indivíduos do sexo masculino com mais de 30 anos e iniciantes na modalidade.

RESUMO

Abstract Objective To analyze the epidemiological data of orthopedic injuries in beach tennis players. Methods We conducted a cross-sectional study, through a questionnaire, with 185 beach tennis players during tournaments and training sessions in two cities. The questionnaire comprised anthropometric data, as well as data on length of time practicing the sport and reported orthopedic injuries. Results We excluded 25 of the 185 interviewees. Of the 160 players studied, 51.9% were male and 48.1%, female. The average age was of 40.4 years, the average height was of 1.73 m, the average weight was of 75.6 kg, and the average body mass index (BMI) was of 25.2 kg/m2. Orthopedic injuries were reported by 48.8% of the participants, 30.0% in the lower limbs, 11.3% in the spine, and 25.0% in the upper limbs, with an incidence of 0.82 per one thousand hours of practice. Correlating the incidence of injuries with age, weight, height, and BMI, we only found relevance between the higher average age in patients with lower- and upper-limb injuries. Players who had no previous experience with other racket sports had fewer injuries. Other parameters, such as gender, use of the two-handed backhand, dominant side, participation in competitions, and practice of other sports did not show statistically significant differences. Conclusion Orthopedic injuries were found in almost half of the beach tennis players, primarily in the lower limbs. Age, experience with other racket sports, category, hours of training per week, and length of time playing the sport influenced the incidence of orthopedic injuries.

Resumo Objetivo Analisar os dados epidemiolügicos das lesões ortopédicas nos praticantes de beach tennis. Métodos Foi realizado um estudo transversal, por meio de questionário, em 185 praticantes de beach tennis, durante torneios e treinos, em duas cidades. O questionário consistiu na coleta de dados antropométricos, além de dados relativos ao tempo de prática do esporte e às lesões ortopédicas referidas. Resultados Excluímos 25 dos 185 entrevistados. Dos 160 praticantes estudados, 51,9% eram do sexo masculino, e 48,1%, do feminino. A média de idade foi de 40,4 anos, a média da estatura foi de 1,73 m, a média do peso, de 75,6 kg, e a média do índice de massa corporal (IMC), de 25,2 kg/m2. A presença de lesões ortopédicas foi relatada por 48,8% dos praticantes, sendo 30,0% nos membros inferiores (MMII), 11,3% na coluna, e 25,0% nos membros superiores (MMSS), com incidência de 0,82 a cada mil horas de prática. Correlacionando a incidência de lesões com idade, peso, altura e IMC, encontramos relevância apenas entre a média de idade maior nos pacientes com lesão nos MMII e MMSS. Os jogadores que não tinham experiência prévia com outros esportes com raquete tiveram menos lesões. Demais parâmetros, como sexo, uso do backhand com duas mãos, lado dominante, participação em competições e prática de outros esportes não obtiveram diferenças estatisticamente significantes. Conclusão Lesões ortopédicas foram encontradas em quase a metade dos praticantes de beach tennis, preferencialmente nos MMII. Idade, experiência com outros esportes de raquete, categoria, horas de treino por semana e tempo de prática do esporte influenciaram na incidência de lesões ortopédicas.

RESUMO

Traumatic muscle injuries (TMIs) and muscle pain (MP) negatively impact athletes' performance and quality of life. Both conditions have a complex pathophysiology involving the interplay between genetic and environmental factors. Yet, the existing data are scarce and controversial. To provide more insights, this study aimed to investigate the association of single-nucleotide polymorphisms (SNPs) previously linked to athletic status with TMI and MP after exercise among Brazilian high-performance athletes from different sports modalities (N = 345). The impact of important environmental determinants was also assessed. From the six evaluated SNPs (ACTN3 rs1815739, FAAH rs324420, PPARGC1A rs8192678, ADRB2 rs1042713, NOS3 rs1799983, and VDR rs731236), none was significantly associated with TMI. Regarding MP after exercise, ACTN3 rs1815739 (CC/CT vs. TT; adjusted odds ratio (aOR) = 1.90; 95% confidence interval (95%Cl), 1.01-3.57) and FAAH rs324420 (AA vs. AC/CC; aOR = 2.30; 95%Cl, 1.08-4.91) were independent predictors according to multivariate binomial analyses adjusted for age (≥23 vs. <23 years), sex (male vs. female), and tobacco consumption (yes vs. no). External validation is warranted to assess the predictive value of ACTN3 rs1815739 and FAAH rs324420. This could have implications for prophylactic interventions to improve athletes' quality of life.

RESUMO

OBJECTIVES: The relationship between sport-related injuries and Para athlete impairment type has not yet been comprehensively studied. This study aimed to describe injury incidence according to athlete impairment type during the London 2012 and Rio 2016 Summer Paralympic Games, by sex, age, Games period, chronicity and anatomical area. METHODS: A combined analysis of 7222 athletes was conducted comprising 101 108 athlete days, using pooled data. Internet sources were used to identify impairments of registered athletes. Impairment types: brain disorders (BD), limb deficiency, neuromuscular disorders (NMD), spinal cord-related disorders, visual impairment (VI) and 'all others' (OTH: impaired passive range of movement, intellectual impairment, leg length difference, short stature and unknown impairments). Results by impairment type are reported as univariate unadjusted incidences (injuries/1000 athlete days; 95% CIs). Statistical significance between impairment types was determined when 95% CIs did not overlap. RESULTS: The overall crude unadjusted incidence of injury was 11.1 (95% CI 10.4 to 11.9), significantly higher in VI (13.7 (95% CI 11.0 to 15.7)) and NMD (13.3 (95% CI 11.1 to 16.1)) compared with BD (9.1 (95% CI 7.7 to 10.8)). Acute (sudden onset) (8.6 (95% CI 7.3 to 10.1)) and lower limb (6.6 (95% CI 5.4 to 8.1)) injuries were higher among athletes with VI, while athletes with NMD had a higher incidence of repetitive (gradual onset) (5.9 (95% CI 4.3 to 8.0)) and upper limb (6.9 (95% CI 5.2 to 9.0)) injuries compared with other impairments. CONCLUSIONS: Incidence and type of injuries differed between athlete impairment types. Athletes with VI or NMD sustained the highest incidence of injury, and athletes with BD had the lowest. Findings of this study can inform the management of competition-related injuries in Para athletes.

RESUMO

Soccer is the most popular sport worldwide, and it is associated with high injury rates, with most of these injuries occurring in the lower extremities. Particularly, in youth soccer players with immature skeleton, the physeal plate is two to five times weaker than the surrounding fibrous structures, and therefore more vulnerable to injury. The physeal plate consists of epiphyses and apophyses, with the former serving as tendon attachment sites and being subject to traction forces. There are two types of apophyseal injury: (i) apophyseal avulsion, which consists of an acute separation across the physeal plate; and (ii) apophysitis, an injury caused by chronic and repetitive contraction of musculotendon unit, leading to inflammation of the growth plate cartilage. Apophyses of the hip and pelvis are the most commonly injured in youth soccer players, due to vigorous contractions during sports activities and the fact that they tend to fuse later compared to other epiphyseal centers, making them more susceptible to injury. In this review, we will discuss the anatomy of lower limb apophyses and clinical and imaging findings of apophyseal injuries in youth soccer players, as well as briefly review treatment options and complications.

RESUMO

PURPOSE: To examine the association of the single nucleotide polymorphism A1470T in the SLC16A1 gene with blood lactate accumulation during a graded exercise test and its associated metaboreflex. METHODS: Forty-six Latin-American men (Age: 27 ± 6 years; Body fat: 17.5 ± 4.7%) performed a graded exercise test on a treadmill for the assessment of maximal oxygen uptake (VO2max), lactate threshold (LT), ventilatory threshold (VT) and the exercise intensity corresponding to maximal fat oxidation rate (FATmax), via capillary blood samples and indirect calorimetry. Genomic DNA was extracted from a peripheral blood sample. Genotyping assay was carried out by real-time polymerase chain reaction to identify the A1470T polymorphism (rs1049434). RESULTS: Genotypes distribution were in Hardy-Weinberg equilibrium (X2 = 5.6, p > 0.05), observing allele frequencies of 0.47 and 0.53 for the A and T alleles, respectively. No difference in VO2max, body composition nor FATmax were observed across genotypes, whereas carriers of the TT genotype showed a higher LT (24.5 ± 2.2 vs. 15.6 ± 1.7 mL kg-1 min-1, p < 0.01) and VT in comparison to carriers of the AA + AT genotypes (32.5 ± 3.3 vs. 21.7 ± 1.5 mL kg-1 min-1, p < 0.01). Both, VO2max and the A1470T polymorphism were positively associated to the LT (R2 = 0.50, p < 0.01) and VT (R2 = 0.55, p < 0.01). Only VO2max was associated to FATmax (R2 = 0.39, p < 0.01). CONCLUSION: Independently of cardiorespiratory fitness, the A1470T polymorphism is associated to blood lactate accumulation and its associated ventilatory response during submaximal intensity exercise. However, the A1470 polymorphism does not influence fat oxidation capacity during exercise in young men.

RESUMO

OBJECTIVE: Evaluate injury trends in Brazilian Jiu Jitsu (BJJ) participation by presenting to U.S. emergency departments over a 10-year period and formulate an injury profile. METHODS: The U.S. Consumer Product Safety Commission's (CPSC) National Electronic Injury Surveillance System (NEISS) database was queried for martial arts related injuries from 1 January 2012 to 31 December 2021. Codes and narratives were examined to compile data for patients sustaining BJJ-related injuries. RESULTS: From 1 January 2012 to 31 December 2021 there were 7,722 (NE = 282,315) ED-diagnosed martial arts related injuries with 911 (NE = 36,023) BJJ-related injuries identified. Regression analysis demonstrated an increasing trend in the annual incidence of Brazilian Jiu Jitsu injuries presenting to the ED (R2 = 0.934; SE = 2.069: p < .0001). Average age was 25.68 years of age (range 4-83). The most common injury diagnoses were sprains/strains and other/not listed at 27.68% and 26.39%. The most commonly injured body parts were the upper trunk, and the shoulder comprising 13.66% and 12.14% of injured body parts, respectively. The most commonly fractured region was toes, at 14.15% of all fractures. The most common dislocations occurred at the shoulder and knee, at 32.49% and 28.45% of dislocations, respectively. The most common mechanisms of injury specifically identified were indeterminate contact between players, fall onto ground, or fall onto another player comprising 18.62% and 17.17%, of injuries, respectively. CONCLUSION: There was an increasing trend of BJJ-related injuries presenting to U.S. Emergency Departments. The most common diagnoses and body parts injured were sprains/strains and upper trunk and shoulder, respectively. The most commonly fractured and dislocated regions were toes and shoulder, respectively. The most common mechanisms of injury were indeterminate contact or falling. This study provides novel information concerning trends in injury and injury profiles for Brazilian Jiu Jitsu related injuries.

RESUMO

Resumo Fundamento: As disparidades nos resultados de saúde entre grupos raciais merecem investigação, mesmo em atletas de elite. Portanto, compreender o impacto da raça na sobrevida pós-medalha em atletas olímpicos brasileiros torna-se essencial. Objetivo: Comparar a sobrevida pós-medalha entre medalhistas olímpicos brasileiros brancos e não brancos de 1920 a 1992. Métodos: Utilizamos dados disponíveis publicamente para um estudo de coorte retrospectivo de todos os medalhistas olímpicos brasileiros de 1920 a 1992 (somente homens). Os atletas foram classificados nos grupos brancos e não brancos usando determinação estruturada de etnia. As análises de Kaplan-Meier calcularam o tempo médio de sobrevida restrito (TMSR) para cada grupo étnico. Uma análise de riscos proporcionais de Cox avaliou as diferenças de sobrevida baseadas na etnia, ajustando para a idade da conquista da medalha e ano de nascimento (p<0,05). Resultados: Entre 123 atletas (73,9% brancos), a idade média da conquista de medalhas foi de 25,03 ± 4,8 anos. Durante o estudo, 18,7% dos atletas brancos e 37,5% dos atletas não brancos morreram (p=0,031). Os atletas brancos tiveram média de idade ao óbito de 75,10 ± 18,01 anos, enquanto os atletas não brancos tiveram idade média de 67,13 ± 14,90 anos (p=0,109). O TMSR para atletas brancos foi de 51,59 (IC 95%, 49,79 - 53,39) anos, e para atletas não brancos foi de 45,026 (IC 95%, 41,31 - 48,74) anos, resultando em um ΔTMSR de 6,56 (IC 95%, 2,43 - 10,70; p=0,0018). A análise multivariada mostrou que atletas não brancos apresentavam maior risco de mortalidade do que atletas brancos (RC 5,58; IC 95%, 2,18 - 14,31). Conclusão: Após a primeira medalha, os atletas olímpicos brasileiros brancos normalmente desfrutam de uma expectativa de vida seis anos mais longa do que seus colegas não brancos, ilustrando uma acentuada diferença de mortalidade e disparidades de saúde entre indivíduos saudáveis no Brasil.

Abstract Background: Disparities in health outcomes among racial groups warrant investigation, even among elite athletes. Therefore, understanding the impact of race upon post-medal survival in Brazilian Olympians becomes essential. Objective: To compare post-medal survival between white and non-white Brazilian Olympic medalists from 1920 to 1992. Methods: This study used publicly available data for a retrospective cohort study on all Brazilian Olympic medalists from 1920 to 1992 (males only). Athletes were classified into white and non-white groups using structured ethnicity determination. Kaplan-Meier analyses computed the restricted mean survival time (RMST) for each ethnic group. A Cox proportional hazards analysis assessed ethnicity-based survival differences, adjusting for medal-winning age and birth year (p<0.05) Results: Among 123 athletes (73.9% white), the mean age of medal achievement was 25.03±4.8 years. During the study, 18.7% of white and 37.5% of non-white athletes died (p=0.031). White athletes had a mean age at death of 75.10±18.01 years, while non-white athletes had an age of 67.13±14.90 years (p=0.109). The RMST for white athletes was 51.59 (95% CI 49.79-53.39) years, while for non-white athletes, it was 45.026 (95% CI 41.31-48.74) years, resulting in a ΔRMST of 6.56 (95% CI 2.43-10.70; p=0.0018). Multivariate analysis showed that non-white athletes had a higher mortality risk than did white athletes (HR 5.58; 95% CI, 2.18-14.31). Conclusion: Following their first medal, white Brazilian Olympians typically enjoy a six-year longer lifespan than their non-white counterparts, illustrating a marked mortality gap and health disparities among healthy individuals in Brazil.

RESUMO

ABSTRACT Introduction: Female participation in sports has reached a milestone in 1972 when a constitutional amendment was implemented to ensure equal opportunities for men and women. Since then, the percentage of participants in competitive sports has grown. In this context became necessary to understand menstrual cycle, contraceptive use, and its individual responses. Objective: To investigate menstrual cycle characteristics, physical and mood symptoms related to vaginal bleeding, and contraceptives used by Brazilian Olympic athletes. Also, to assess if these athletes relate that vaginal bleeding influences sportive performance, how they manage it and what can be changed to improve their health care and sportive performance. Additionally, we propose specialized female care by a gynaecologist specialized in sports medicine. Methods: Descriptive observational study was conducted from July to August 2016 and included 118 Brazilian Olympic female athletes, in menacme. The athletes completed a self-administered online questionnaire, adapted from Pre-Participation Gynaecological Examination of female athletes. Results: Participants practiced 28 different sports, mean age 27 ± 4.7 years. For 66% it was their first participation in an Olympic Game. Most used contraceptives (54%), mainly oral (61%). Most (76%) believed that vaginal bleeding influenced sports performance, and 63% preferred to compete after bleeding cessation. Fifty-eight percent would compete at preferred time of their cycle. Anxiety symptoms, bloating, increased appetite, depression, and dysmenorrhea were indicated by 52%. Among these, 49% reported that these symptoms deteriorated their sportive performance. Conclusion: Most in their first Olympic participation, Brazilian athletes used hormone contraceptives, mainly oral ones to manage and adapt their vaginal bleeding to the competition calendar because most of them referred those physical and mood symptoms deteriorated their sportive performance. The presence of a Sportive Gynaecologist as part of the Olympic Medical Staff highlighted the female athletes issues and helped them to improve sportive performance.

RESUMEN Introducción: La participación femenina en deportes alcanzó un hito en 1972, cuando se implementó una reforma constitucional para garantizar igualdad de oportunidades entre hombres y mujeres. Desde entonces, el porcentaje de participantes en deportes competitivos ha crecido. En este contexto, se hizo necesario comprender el ciclo menstrual, el uso de anticonceptivos y sus respuestas individuales. Objetivo: Investigar características del ciclo menstrual, síntomas físicos, estado de ánimo, quejas relacionadas con el sangrado vaginal y los métodos anticonceptivos utilizados por atletas olímpicas brasileñas. Evaluar si estas deportistas perciben influencia del sangrado vaginal en el rendimiento deportivo, cómo lo controlan y qué se puede cambiar para mejorar. Además, ofrecemos atención especializada por una ginecóloga especialista en medicina deportiva. Métodos: Estudio observacional, descriptivo, realizado de julio a agosto de 2016, que incluyó 118 atletas olímpicas brasileñas, en menacme. Las atletas respondieron un cuestionario en línea autoadministrado y adaptado titulado "Examen ginecológico previo a la participación". Resultados: Practicaban 28 deportes diferentes, con edad media = 27 ± 4,7 años. Para 66%, era su primera participación en un juego olímpico. Anticonceptivos usados r54%), principalmente orales (61%).

RESUMO

Chronic exertional compartment syndrome (CECS) is a challenging pathology that causes pain and physical limitations. Fasciotomy is the gold standard and different techniques have been described. Techniques that allow a fast return to sports and low recurrence rates are of great interest for the athletic population. This is a prospective case series presenting a mini open surgical technique and its results regarding the level of return to sports and quality of life in 13 patients. A specific CECS questionnaire was applied and analyzed concerning the distance patients were able to run before and after treatment, Tegner score, Medical Outcomes Short-Form Health Survey (SF-36), and epidemiological measures. The minimum follow-up was 12 months. The mean distance the patients were able to run per week following the surgical treatment improved from 14.1 to 38.1 km (P = .042) and the mean Tegner score improved from 3.92 to 7.08 (P = .01). Notably, 12 out of 13 patients were satisfied or very satisfied with the outcome. In this sample, the mini open technique improved patients' sports performance and quality of life and minimized pain. Chronic exertional compartment syndrome can be safely approached using a mini open technique with a good rate of satisfaction and return to sport.Levels of Evidence: IV.

RESUMO

INTRODUCTION: Worldwide, the prevalence of degenerative diseases such as dementia and mild cognitive impairment (MCI) is increasing with population ageing and increasing life expectancy. Both conditions share modifiable risk factors. Physical inactivity is one of these modifiable risk factors, and research points to the protective effect of physical activity on the incidence of dementia and MCI. However, this association tends to change according to type, intensity, frequency, duration and volume of physical activity. Furthermore, it remains unclear which of these characteristics offers the greatest protective effect. Therefore, this study aims to evaluate the impacts of different types, intensities, frequencies, duration and volume of physical activity on dementia and cognitive decline in older adults. METHODS AND ANALYSIS: The search will be carried out from October 2023, using the following databases: PubMed, Embase, Scopus, CINAHL and Web of Science. Cohort studies with a follow-up time of 1 year or longer that have investigated the incidence of dementia and/or MCI in older adults exposed to physical activity will be included. There will be no limitations on the date of publication of the studies. Studies published in English, Spanish or Portuguese will be analysed. Two researchers will independently screen the articles and extract the data. Any discrepancies will be resolved by a third reviewer. Association measures will be quantified, including OR, HR, relative risk and incidence ratio, with a 95% CI. If the data allow, a meta-analysis will be performed. To assess the methodological quality of the selected studies, the Grading of Recommendations, Assessment, Development and Evaluations instrument, and the Downs and Black instrument to assess the risk of bias, will be used. ETHICS AND DISSEMINATION: Ethical approval is not required. The results will be submitted for publication in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42023400411.

RESUMO

Introducción: La dificultad y la ejecución de los elementos desempeñan un papel importante en las competiciones de la gimnasia artística masculina. Sin embargo, resultan escasos los estudios que evalúen la técnica de los ejercicios en esta modalidad. Objetivo: Diseñar un instrumento para la evaluación de la calidad del desempeño en la técnica de los ejercicios de barras paralelas en gimnasia artística masculina. Método: Participaron 3 gimnastas juveniles masculinos de la Selección Norte de Gimnasia Artística Masculina (edad 15,67 ± 0,58; talla 1,65 ± 0,08 m; masa corporal 55,67 ± 3,40 kg; IMC 20,37 ± 0,69; grasa corporal 5,90 ± 0,61 por ciento; masa muscular 46,50 ± 2,85 por ciento; experiencia 9,75 ± 0,96 años; competiciones nacionales 7,00 ± 0,82; competiciones internacionales 5,50 ± 1,29). El diseño se estructuró a partir de cada elemento de la rutina en barras paralelas y se determinaron indicadores de calidad, dificultad, ejecución, entre otros. Se pronosticó la rutina a ejecutar y se comparó con los resultados en competición real. Resultados: El puntaje pronosticado resultó similar al de la competencia. No hubo diferencias estadísticamente significativas con el valor obtenido en la competición (p> 0,05). Conclusiones: Este diseño constituye una herramienta viable para estructurar rutinas en barras paralelas. Como permite obtener resultados similares a los de competiciones, puede controlar el entrenamiento y las competencias de gimnastas masculinos juveniles(AU)

Introduction: The difficulty and performance of the apparatuses play an important role in men's artistic gymnastics competitions. However, there are few studies evaluating the exercise technique in parallel bars. Objective: To design an instrument for evaluating the quality of performance in the technique of parallel bars exercises in men's artistic gymnastics. Method: Three male young gymnasts, from the North Men's Artistic Gymnastics Team, participated (age 15.67 ± 0.58; height 1.65 ± 0.08 m; body mass 55.67 ± 3.40 kg; BMI 20.37 ± 0.69; body fat 5.90 ± 0.61 percent; muscle mass 46.50 ± 2.85 percent; experience 9.75 ± 0.96 years; national competitions 7.00 ± 0.82; international competitions 5.50 ± 1.29). The design was structured based on each apparatus of the routine in parallel bars and indicators were determined in quality, difficulty, performance, among others. The routine to be performed was predicted and compared with the results in real competition. Results: The predicted score was similar to that of the competition. There were no statistically significant differences with the value obtained in the competition (p > 0.05). Conclusions: This design constitutes a viable tool to structure routines on parallel bars. In addition, it can control the training and competitions of young male gymnasts because it allows obtaining results similar to those of competitions(AU)
