Quad comparison at 20 days post-injury. It’s amazing how quickly my right quad has disappeared in such a short time. Studies show that after an injury, muscle can atrophy up to 0.5% each day. EACH. DAY. 😩
After an injury, a muscle atrophies at a significantly higher rate than if you were to just not hit the gym for a few weeks. While disuse of a muscle would be a common factor between injury and laziness, there are other hormonal and signaling factors involved with an injury that contribute to increased muscle loss. For instance, after an injury, myostatin signaling is greatly increased, which inhibits muscle cell growth and differentiation, and TGF-β1 is greatly increased, which promotes cell death. These are two important factors- and they aren’t even half of this very complex equation.
Due to such a large atrophy rate, I would argue that serious injuries more seriously affect and set back a strength-based athletes as opposed to a skill-based athletes. This probably also affects perceived recovery time on the part of the athlete. In conclusion, injuries suck and my quad is small. 🧐 #rambling #powerlifter #strongman #aclreconstruction #aclrecovery
