ABSTRACT

Introduction:

Soccer referees need excellent conditioning to withstand the physical and psychological demands of games.

Objective:

To compare the hemodynamic variables, speed, cadence, and distance coursed of referees during soccer gamesof series A and B in Rio de Janeiro, Brazil. Material and

method:

The total number of decisions made during the 10 soccer matches evaluated was 1,224 observabledecisions of 10 professional Soccer referees (one per soccer match 5 in series A and 5 in series B). We used a frequency meter(Polar, model V800, PolarFlow software) and video footage of the games (Sony, model PXW-Z150, 4K). The moments considered were the decision, 15 seconds that preceded it, and the period from the beginning of each stage to each decision. Were studied the hemodynamic [average heat rate (mean HR), maximum heart rate (HRmax), and minimum heart rate (HRmin)]and motion variables [average speed (Vmed), maximum speed (Vmax), average cadence (cadencemed), maximum cadence(cadencemax), minimum cadence (cadencemin), and distance covered]. Descriptive measures were used to present the resultsof the variables studied and the Student’s T-Test for independent samples to test the study hypotheses. The significance levelwas set at 95% (P <0.05).

Results:

The matches of series A had a greater number of interventions and greater hemodynamic load at the exact momentof the decision than those of series B. significantly (P <0.05) mean HR, HRmax, HRmin, Vmax, Cadencemed, and Cadencemax in seriesA were higher compared to series B. In the 15 seconds before the decisions mean HR, HRmax, and HRmin in series A were higherthan in series B, and Vmed in series B was higher in relation to series A. At the exact moment of the decisions mean HR in seriesA was higher in relation to series B...(AU)
RESUMEN

Introducción:

Los árbitros de fútbol necesitan un excelente acondicionamiento para soportar las exigencias físicas y psicológicas de los partidos.

Objetivo:

Comparar las variables hemodinámicas [frecuencia cardíaca media (mean HR), frecuencia cardíaca máxima (HRmax)y frecuencia cardíaca mínima (HRmin)] y desplazamiento [velocidad media (Vmed), velocidad máxima (Vmax), cadencia media(cadencemed), cadencia máxima (cadencemax), cadencia mínima (cadencemin) y distancia recorrida] durante intervencionesarbitrales en partidos entre las series A y B en Río de Janeiro, Brasil. Material y

método:

Se analizaron 1.224 decisiones observables de 10 árbitros profesionales de fútbol cada uno en 1 partido(10 partidos del Campeonato Carioca 5 en la serie A y 5 en la B). Se utilizaron frecuencímetros (Polar, modelo V800, softwarePolarFlow) y secuencias de video de los juegos (Sony, modelo PXW-Z150, 4K). Los momentos considerados fueron la decisión,los 15 segundos que la precedieron y el tiempo desde el inicio de cada etapa hasta cada decisión.

Resultados:

Los partidos de la serie A tuvieron mayor número de intervenciones y mayor carga hemodinámica en el momentoexacto de la decisión que los de la serie B. significativamente (p <0,05) mean HR, HRmax, HRmin, Vmax, cadencemed y cadencemaxin la serie A fueron mayores que en la serie B. En los 15 segundos previos a las decisiones mean HR, HRmax y HRmin en la serieA fueron mayores con relación a la serie B, la Vmed en la serie B fue mayor en relación a la serie A.

Conclusión:

Las intervenciones de los árbitros generalmente se realizan bajo presión hemodinámica elevada. Los partidosdisputados en la serie A requieren un número de intervenciones e intensidad hemodinámica superior a los partidos de laserie B...(AU)
