The study analyzed the physical conditioning and the time of recovery of the maximum heart rate of 12 international referees being used the test of 20 meters with beep to evaluate the cardiorespiratory conditioning, with the frequency to control the recovery time of the maximum cardiac post test. The majority of the referees obtained a recovery of heart rate greater than 50% in 3 minutes, were those that reached the levels of good to excellent in the table of maximum Vo2. Even with some factors influencing their physical performance most of the referees were able to complete the aerobic test and obtained a good recovery of the heart rate, the others that failed to reach the test goal had the HR recovery in 3 minutes much lower than expected, thus highlighting the association of the maximum VO2 level between good and excellent with the recovery of the heart frequency.
El objetivo principal de este trabajo fue verificar las propiedades psicométricas del Inventario de Burnout para Árbitros en árbitros de baloncesto brasileños. Fueron evaluados un total de 395 árbitros de baloncesto (edad: 35.11 ± 9.18 años), de ambos sexos (masculino = 319 y femenino = 76), con un tiempo de experiencia promedio de 12.34 ± 7.83 años, quienes respondieron cuestionarios de identificación demográfica, Burnout Inventory for Brazilian Basketball Referees (BIR-AB) y Brunel Mood Scale for Basketball Referees (BRUMS-AB). La validez factorial se estimó mediante el análisis factorial confirmatorio (AFC) con el método de estimación de máxima verosimilitud. Como se rechazó la homocedasticidad, la comparación entre grupos se realizó mediante ANOVA con corrección de Welch seguido del post-test de Games-Howell. La correlación entre las puntuaciones de los factores BIR-AB y las variables edad y duración de la experiencia se evaluó mediante el análisis de correlación de Pearson (r). El nivel de significancia adoptado fue del 5%. Tras la realización del AFC e inserción del modelo jerárquico de segundo orden (MHSO), se propuso un nuevo modelo, denominado BIR-AB (Burnout Inventory for Referees para árbitros brasileños de baloncesto), que contiene dos dimensiones negativas (agotamiento físico y emocional y despersonalización) y una positiva (rendimiento deportivo), con índices de ajuste adecuados, se constató una confiabilidad aceptable e invariante entre el género y en la muestra de prueba / validación y la validez divergente. The main goal of this paper was to verify the psychometric properties of the Burnout Inventory for Referees on Brazilian basketball referees (BIR-AB). A total of 395 basketball referees were evaluated (age: 35.11 ± 9.18 years), of both gender (male = 319 and female = 76), with an average experience time of 12.34 ± 7.83 years, who answered demographic identification questionnaires, Burnout Inventory for Brazilian Basketball Referees (BIR-AB) and Brunel Mood Scale for Basketball Referees (BRUMS-AB). Factor validity was estimated using Confirmatory Factor Analysis (CFA) with the Maximum Likelihood estimation method. As homoscedasticity was rejected, the comparison between groups was performed using ANOVA with Welch's correction followed by the Games-Howell post-test. The correlation between the scores of the BIR-AB factors and the variables age and length of experience was assessed using Pearson's Correlation Analysis (r). The level of significance adopted was 5%. After the performance of the CFA and insertion of the second-order hierarchical model (MHSO), a new model was proposed, called BIR-AB, containing two negative dimensions (physical and emotional exhaustion and depersonalization) and a positive (sport performance), with adequate adjustment indexes, acceptable and invariant reliability between the gender and in the test/validation sample and the divergent validity was attested. O objetivo principal desse estudo foi verificar as propriedades psicométricas do Burnout Inventory for Referees para árbitros brasileiros de basquetebol. Foram avaliados 395 árbitros de basquetebol (idade: 35,11 ± 9,18 anos), de ambos os sexos (masculino=319 e feminino=76), com tempo médio de experiência de 12,34 ± 7,83 anos, que responderam aos questionários de identificação demográfica, Burnout Inventory for Brazilian Basketball Referees (BIR-AB) e Brunel Mood Scale for Basketball Referees (BRUMS-AB). A validade fatorial foi estimada utilizando-se a Análise Fatorial Confirmatória (AFC) com método de estimação da Máxima Verossimilhança. Como a homocedasticidade foi rejeitada, a comparação entre os grupos foi realizada por meio da ANOVA com correção de Welch seguido pelo pós-teste de Games-Howell. A correlação entre os escores dos fatores do BIR-AB e as variáveis idade e tempo de atuação foi avaliada a partir da Análise de Correlação de Pearson (r). O nível de significância adotado foi 5%. Após a realização da AFC e inserção do modelo hierárquico de segunda ordem (MHSO), um novo modelo foi proposto, chamado de BIR-AB (Burnout Inventory for Referees para árbitros brasileiros de basquetebol), contendo duas dimensões negativas (exaustão física e emocional e ) e uma positiva (desempenho esportivo), com índices adequados de ajustamento, confiabilidade aceitável e invariante entre os sexos e na amostra teste/validação e a validade divergente foi atestada.
