Efectos de los enjuagues con carbohidratos en el rendimiento de triatletas en una prueba de ciclismo de 40 km
Resumen
El objetivo de este estudio fue investigar los efectos del enjuague bucal con carbohidratos en el rendimiento de triatletas en una prueba de ciclismo de 40 km, tras nadar 1,5 km. En un diseño experimental aleatorizado, ciego y cruzado, trece triatletas varones (edad: 29,69 ± 7,8 años; experiencia de entrenamiento: 2,5 ± 1,19 años; VO2máx: 51,33 ± 6,04 ml·kg⁻¹·min⁻¹) realizaron una contrarreloj con velocidad autorregulada en dos condiciones: enjuague bucal placebo (PLA) y enjuague bucal con carbohidratos (CHO). Los resultados no mostraron diferencias significativas en las duraciones medias de la prueba contrarreloj (PLA: 72 min 13 s ± 3 min 30 s y CHO: 72 min 55 s ± 3 min 20 s; p = 0,789; d = 0,08), la potencia relativa (PLA: 2,74 ± 0,23 W/kg; CHO: 2,74 ± 0,25 W/kg; p = 0,945; d = 0,02), la velocidad media (PLA: 33,04 ± 1,28 km/h; CHO: 32,98 ± 1,21 km/h; p = 0,785; d = 0,09), la frecuencia cardíaca media (PLA: 148,00 ± 11,51 lpm; CHO: 149,00 ± 10,78 lpm) y la frecuencia cardíaca de Esfuerzo Percibido (PLA: 5,41 ± 0,99; CHO: 5,50 ± 1,22; p = 0,704; d = 0,08). En conclusión, el enjuague bucal con carbohidratos podría no ser efectivo para mejorar el rendimiento en triatletas.
