Complete Fitness & Plasticity of Aging Research
The term "plasticity" refers to the ability to mold or change the shape of something. Aging is all about change, some of it positive, some of it negative, and some of it neutral. There are some declines that are inevitable with age, such as arterial wall rigidity, kidney reserve, and impaired chemical regulations.
Early work in this program was designed to look at the nature of change within the respiratory system of older adults. It is clear that the diaphragm loses its capacity to work at maximum power and the lungs lose their elasticity. This impacts performance even in those who may run marathons all their life.
Nevertheless, the majority of older adults have major reductions (up to 50%) in their endurance capacity in part from aging, but equally from sedentary living. Our society at all ages is faced with an "inactivity epidemic" which is translating into obesity, Type 2 diabetes, and coronary heart disease at much earlier ages. This is where the term "plasticity" comes in. For most people, it is never too late to improve the risk profile. Specifically, it is possible to recapture strength, aerobic capacity and mobility. Older adults should not expect to become an Olympic athletes - instead, their goal should be to remain functionally independent for as long as possible. There is considerable research evidence demonstrating that the body is still "plastic" into the 90s and that this plasticity can result in changes to functional abilities.
The literature is also clear in revealing that the secret of maintaining functional independence is to maintain or improve fitness level. Light, modest physical activity may not be sufficient to delay or forestall the loss of function in various body systems. On the other hand, brisk walking, balance-mobility practice, and strength training are very good investments to enhance functional fitness in older adults. The kinesiologists employed at the Schlegel Villages are well-positioned and well-trained to assist residents in fulfilling this worthwhile objective.
