Resumen
Este estudio tuvo como objetivo comprobar la fiabilidad absoluta y validez concurrente del monitor de frecuencia
cardiaca HRM-Run (Garmin), para medir variables espaciotemporales durante la carrera a diferentes velocidades (9 y
12 km/h), mediante la comparación de datos con otros dispositivos ampliamente utilizados (Stryd y OptoGait). 51
sujetos realizaron una prueba de carrera a velocidad de 9 km/h y 12 km/h en una cinta rodante, durante un minuto. Se
midió la cadencia de carrera (CC), el tiempo de contacto (TC) y la oscilación vertical (OV) utilizando 3 dispositivos
diferentes (banda HRM-Run Garmin, sistemas Stryd y OptoGait). El análisis de correlación de Pearson mostró un alto
nivel de correlación en la variable cadencia entre el Garmin vs. OptoGait, a velocidades de 9 y 12 km/h (r =0,723 y r
= 0,657 respectivamente), así como un alto nivel de fiabilidad en la prueba Alpha de Cronbach en la variable cadencia,
entre el Garmin vs. Stryd y el Garmin vs. OptoGait en las dos velocidades analizadas. En conclusión, el monitor de
frecuencia cardiaca (HRM-Run Garmin) es un dispositivo válido y fiable para medir la CC debido a que existen altos
niveles de validez y fiabilidad entre los dispositivos, mientras que en las otras dos variables muestran unos
bajos/moderados niveles de correlación por lo que no podemos confirmar su validez.
This study aimed to test the absolute reliability and concurrent validity of the HRM-Run heart rate monitor (Garmin), for measuring spatiotemporal variables during running at different speeds (9 and 12 km/h), by comparing data with other widely used devices (Stryd and OptoGait). 51 subjects performed a running test at speeds of 9 km/h and 12 km/h on a treadmill for one minute. Running cadence (CC), contact time (CT) and vertical oscillation (VO) were measured using 3 different devices (Garmin HRM-Run band, Stryd and OptoGait systems). Pearson's correlation analysis showed a high level of correlation in the cadence variable between the Garmin vs. OptoGait, at speeds of 9 and 12 km/h (r =0,723 y r = 0,657 respectively), as well as a high level of reliability in the Cronbach's Alpha test in the cadence variable, between the Garmin vs. Stryd and the Garmin vs. OptoGait at the two speeds analysed. In conclusion, the heart rate monitor (HRM-Run Garmin) is a valid and reliable device for measuring CC due to high levels of validity and reliability between the devices, while the other two variables show low/moderate levels of correlation so we cannot confirm their validity.
