Active Aging – The Benefits of Exercise to Keep the Body Systems Functioning Properly

Part 1 – Exercise and the Endocrine System

As we age, it is even more important to exercise consistently and include higher intensity workouts more frequently. Exercise is vital to the body’s ability to function efficiently and repair itself. The benefits of consistent exercise to one’s health are almost countless. The 12 main systems of the body depend on movement as a major component of homeostasis (The state of maintaining healthy biochemical and physiological processes within the body). For instance, regular physical activity is necessary for the proper function of the endocrine system.

The endocrine system is comprised of a number of glands that are responsible for the production and secretion of hormones into the blood stream in order to be transported to organs and tissue. These hormones perform a number of intrinsic functions such as regulating body temperature, blood pressure, energy production, maintaining proper hydration, immune function, cell repair and production (which include muscle, bone and tissue production), blood sugar levels, digestion, sleep quality, alertness levels, reproductive health and sexual function.

Stimulation of hormone production with regular challenging exercise increases insulin sensitivity levels which regulates blood sugar. Increased hormone production also boosts heart health, and the body’s ability to fight illness and stress related maladies by widening blood vessels in order to circulate increased blood concentrations of oxygen, immune cells and endorphins, throughout the body more quickly. Resistance training and short bursts of high intensity exercise which create mechanical and metabolic stress stimulate testosterone, estrogen and growth hormones which promote muscle, bone and tissue cell development, increases metabolism, concentration, memory and motivation.

The appropriate exercise programs as one ages, will keep the systems of the body working efficiently which is essential in order to keep minimizing the risk of chronic disease and injury, maintain energy levels and optimal biomechanical function. These are key elements in achieving and preserving a healthy quality of life throughout later years.
