Zusammenfassung:The purpose of this study was to analyze the external and internal load of Costa Rican handball referees according to sex and game periods. Nine referees (6 men and 3 women) were monitored during U19 handball matches, using an ultra-wide band local positioning system (UWB) and WIMUPro™ inertial units (IMU). The results showed a total distance of 4566.54±494.02 m (46.95% at 0-6 km/h, 32.97% at 6-12 km/h, 18.11% at 12-18 km/h and 1.96% >18 km/h). 1298.34±151.42 m/s2 accelerations and 1297.73±152.09 m/s2 decelerations were performed. Maximal speed was 19.63±1.85 km/h and average speed was 4.80±0.34 km/h. Player LoadRT was 50.53±9.39 UA. Maximal and average heart rate was 170.59±18.20 bpm 143.06±16.94 bpm respectively. 60% of the efforts were 18 km/h, average speed, impacts at 3-5g and >5g, Player LoadRT, and energy expenditure decreased. In conclusion, sex does not seem to affect the external or internal load, while the game period influenced on the external load El propósito de este estudio fue analizar la carga externa e interna de árbitros costarricenses de balonmano según sexo y periodos de juego. Nueve árbitros (6 hombres y 3 mujeres) fueron monitoreados durante partidos de balonmano Sub-19, utilizando un sistema de posicionamiento local de banda ultra ancha (UWB) y unidades inerciales WIMUPro™(IMU). Los resultados mostraron una distancia total de 4566.54±494.02 m (46,95% a 0-6 km/h, 32,97% a 6-12 km/, 18,11% a 12-18 km/h y 1,96% a >18 km/h. Se realizaron 1298.34±151.42 m/s2 aceleraciones y 1297.73±152.09 m/s2 desaceleraciones. La velocidad máxima fue 19.63±1.85 km/h y la velocidad promedio fue 4.80±0.34 km/h. Player LoadRT fue 50.53±9.39 UA. La frecuencia cardíaca máxima y promedio fueron 170.59±18.20 lpm y 143.06±16.94 lpm respectivamente. El 60% de los esfuerzos fueron 18 km/h, velocidad media, impactos a 3-5 g y > 5g, Player LoadRT y gasto
