Muscle function is reduced in older adults as a result of aging and inactivity. The largest reduction is seen in the lower limbs and trunk extensors (lower back, etc.). In addition, there is more loss of our type II fibers which are mainly responsible for power and strength (aiding in our anaerobic activity).
While one’s strength to mass ratio also decreases, one’s ability to adapt to a resistance training program is not affected by aging. For instance, if a 20 year old and a 60 year old man were to start the same strength training program they would both have roughly the same percentage of strength gains, the only difference being that the younger man would start off as having a higher muscle mass to begin with.

That is why it is so important for older adults to continue doing strength training as there are lots of rewards. Benefits include increased muscle fiber size (hypertrophy), reduced body fat percentage, increased muscle contractile strength, improved physical functioning as you age, and much more.
