Effect of WP containing supplements in RT individuals

Naclerio & Larumbe-Zababala, Sport Med 2015

Beef is a nutrient-rich, high-quality protein containing all the essential amino acids in proportions similar to those found in human skeletal Muscle (Chernoff, R. JACN. 2004)

Beef supplements? Hydrolysed meat protein are easily digested and absorbed (Negro et al 2014)

key points

The best protein sources:

Contain higher amount of EAA (>40%)   At rest, slower AA absorption & less oxidation

rate (Soeters et al 2001)   After exercise or long fasting period, a

relatively higher AA absorption and less oxidation rate (Soeters et al 2001)

FSR of the vastus lateralis in young adults (n=19) during the post-exercise recovery period following ingestion of the PB

(50% C; 25% WP & 25%S) or WP 1 h post RE (Reidy et al 2013 JN)

Interesting, FSR increased equivalently in both groups during the early period but remained elevated only in the PB group during the late period (P < 0.05)

Possible effective protocol during peri-workout time

Naclerio et al JSMDS, 2013

Puntos clave

  La ingesta de entre 100 a 400 mg/kg de proteinas de alta calidad, cada 3 a 4 hr, parecen determinar un rango de dosis mínimas a óptimas para estimular la SPM y atenuar la disrupción de la membrana muscular durante el reposo o en condiciones de ejercicio.

  Los preparados en donde se combinan proteínas de diferentes fuentes (leche, carne, o soja) serian una alternativa apropiada para optimizar la nutrición y apoyar los procesos de adaptación al entrenamiento.
