How Protein Affects Performance

April 2017 by Dr Jennifer Stewart, BVSc, BSc, PhD, MRCVS, Dip BEP, AAIM, Jen Equine,

Protein features frequently in discussions on feeding, nutrition and performance. Alternately feared and revered, protein is part of the bigger picture of conditioning and nutritional protocols that result in specific changes in body composition and performance.

The word protein comes from the Greek word ‘protos’, meaning ‘first’, because protein is the primary basic constituent of all living cells. Protein makes up three-quarters of the dry weight of most living cells and is involved in the formation of hormones, enzymes, antibodies and many other functions essential to life.

Protein is a collection of amino acids tied together. Once the protein is consumed and digested, the amino acid chains breakdown into single amino acids.
