Muscle bulk
It is important that older people (i.e age 70+) maintain muscle bulk for falls prevention and joint stability.
As people age, it is even more important to remain physically active.
For many, ‘retirement’ at 65 can mean retiring from a former active lifestyle into a sedentary existence.
Being sedentary and not participating in exercise has a number of significant and adverse health effects.
Decline in cardiac fitness = decrease in capacities like doing simple things such as showering and dressing.
Becoming sedentary can be a self-fulfilling prophecy. Once diseases develop that are related to this lifestyle, such as arthritis, physical activity may become more challenging making the whole problem worse.
