Resumen
El objetivo del estudio fue examinar los efectos de un período de entrenamiento de 6 meses de CrossFit sobre el rendimiento físico, eficiencia metabólica, composición corporal y parámetros bioquímicos. Diez practicantes habituales de CrossFit fueron evaluados antes y después de 6 meses de entrenamiento. Medidas antropométricas, sanguíneas y parámetros de rendimientos fueron medidos a través de test funcionales y un test incremental. Tras seis meses de CrossFit, el ratio de oxidación y porcentaje de energía de grasa obtenido se incrementó significativamente (+221.43%; p=.043 and +222.39%; p=.043 respectivamente) en detrimento de los valores de hidratos de carbono en valores máximos (-47.35%; p=.043 and -34.41%; p=.043 respectivamente). En la zona de máxima oxidación de grasa, el volumen de oxígeno máximo incrementó (+20.3%; p=.043). El ratio de oxidación de grasa aumentó significativamente en detrimento del ratio de carbohidratos (+62.75% vs -27.67%; p=.043). Los valores de lactato deshidrogrenasa incrementaron significativamente (+27.13%; p= .043). En conclusión, seis meses de CrossFit mejora la eficiencia metabólica en cuanto al ratio de oxidación de grasa, sin conllevar daños musculares.
