Ageing and Bones, Muscles and Joints
May the force be with you. No really lifting weights really helps.
People’s posture changes as they age. Bone density can be lost and spinal vertebrae can be compressed, making the upper body look shorter or curved. Joints are generally stiffer and less flexible.
Muscles usually becomes less dense, making the arms and legs look thinner. Muscle tissue may also become less flexible and muscles can lose tone (become flabby).
How does exercise help?
Exercise helps to slow or prevent bone and muscle loss, and good nutrition, including calcium, can help seniors maintain strength and good health.
Ageing and Organs, Tissue and Cells
Cells are the basic building blocks of tissue and with ageing, cells grow larger and less able to reproduce. This can cause connective tissue (bones, blood, and lymph, for example), to become more stiff, which makes blood vessels and organs more rigid. Our skin loses fat, and can become thinner and more susceptible to injury. Muscle tissue can lose density, becoming less strong.
As cells and tissues become more rigid, this affects internal organs, especially the heart, lungs and kidneys. Most important, organs can lose their reserve, or ability to increase function at higher levels. Heart failure is an example of an organ’s failure to increase its level of functioning during a time of increased stress or activity.
While the effects of aging on cells, tissues and organs are a normal part of aging, the good news is that these changes usually appear over a long period of time, and exercise and good nutrition can play an important part in keeping the body healthy longer.
Ageing and Hormones
Hormones are natural chemicals produced in the organs of the endocrine system. They are secreted into the bloodstream to be used by other organs and systems in the body. Ageing changes the way hormones are used in the body; some hormone levels decrease, and some are metabolized more slowly.
