El uso de sistemas válidos, precisos y fiables es decisivo para garantizar una recogida de datos óptima y una interpretación correcta de los datos. Entre otros factores, parece que la frecuencia de muestreo y el número de antenas determinan la precisión de los datos utilizando sistemas de posicionamiento local (LPS). Por lo tanto, el objetivo de este estudio fue evaluar y comparar la precisión de dos configuraciones ultra banda ancha (UWB) (UWB6_18HZ: 6 antenas y 18 Hz de capacidad frente a UWB8_33HZ: 8 antenas y 33 Hz de capacidad) para medir los patrones de movimiento en los deportes. Un jugador de fútbol sano y bien entrenado (edad: 38 años, masa: 76,34 kg, altura 1,85 m) corrió 9 m a lo largo de la línea media de una cancha de voleibol (n = 10 recorridos, muestras = 424). Las configuraciones UWB6_18HZ y UWB8_33HZ han mostrado una alta precision (diferencia media entre las mediciones reales y UWB = 0.014 ± 0.03m frente a UWB6_18HZ y 0.013 ± 0.03m para UWB8_33HZ), aunque UWB8_33HZ presentó mayor precisión (8.99 ± 0.03 m_18HZ_18) que UWB6_18HZ (8,94 ± 0,03). Por lo tanto, los fabricantes deben considerar desarrollos futuros basados frecuencias de muestreo y número de antenas instaladas alrededor de la cancha.
