yes - But also consider the following. (which im sure you’re aware of - just putting it out there)
In addition to general skeletal muscle loss, the following changes occur as you age:
Muscles take longer to respond to brain signals in your 50s than they did in your 20s. As a normal course of aging, you begin to lose the muscle fibers that are responsible for making you move quickly. The speed of transmission of impulses from the brain to the muscles also slows down, so it takes longer to get the signal, “Hey! Move it!” Your muscles also can’t repair themselves as quickly as they used to, due to a decrease in enzyme activities and protein turnover.
The water content of tendons (the cord-like tissues that attach muscles to bones) decreases as you age. This change makes the tissues stiffer and less able to tolerate stress.
Your heart muscle becomes less able to propel large quantities of blood quickly through your body. As a result, you tire more quickly and take longer to recover.
