New study on cold water immersion (cwi) and it’s effect on myofibrillar protein syntheses (post-workout).

Key Points      

Protein ingestion and cooling are strategies employed by athletes to improve post exercise recovery and, as such, to facilitate muscle conditioning. However, whether cooling affects postprandial protein handling and subsequent muscle protein synthesis rates during recovery from exercise has not been assessed.        

This study investigated the effect of post exercise cooling on the incorporation of dietary protein‐derived amino acids into muscle protein and acute postprandial (hourly) as well as prolonged (daily) myofibrillar protein synthesis rates during recovery from resistance‐type exercise over 2 weeks.  

Cold‐water immersion during recovery from resistance‐type exercise lowers the capacity of the muscle to take up and/or direct dietary protein‐derived amino acids towards de novo myofibrillar protein accretion. In addition, cold‐water immersion during recovery from resistance‐type exercise lowers myofibrillar protein synthesis rates during prolonged resistance‐type exercise training.        

My man, Jack LaLanne, got it right: Life is a battlefield. You’ve got to dominate it.
