The 1975 rat study reports that aging increases the **insoluble collagen fraction** and decreases the **salt-extractable collagen fraction** in red, white, and cardiac muscle. The 2010 human resistance-exercise study reports that intramuscular **collagen fractional synthesis rate (FSR)** is evenly elevated after both light-load and heavy-load knee-extension exercise and is **not affected by feeding**, while **myofibrillar FSR** responds only to heavy load and is further increased by feeding."]}
