Exercise is supposed to be the answer for myriad health concerns – from cardio-respiratory fitness and blood pressure maintenance to weight control – but there are those of us who may feel that, no matter how much we exercise, we don’t see much in the way of results. Turns out, it may not be in our heads.
Fitness experts estimate that anywhere from 20 to 45 percent of those who undertake a form of regular exercise experience no measurable physiological change as a result – and they even have a name for us: non-responders.
“Although it would appear to be intuitive that all previously untrained and sedentary individuals undertaking exercise can expect positive changes to their physiological function and overall health, the scientific literature is quite clear that for a segment of the population this is indeed not the case,” says Lance Dalleck, associate professor of exercise and sport science and director of the Center for Wellness and Human Performance at Western State Colorado University, who has done research on non-responders.
One unfortunate effect of the phenomenon is that non-responders can become frustrated with their lack of progress and decide it’s not worth it to stick with their exercise program – or, really, any exercise program.
But recent research has indicated non-responders to one form of exercise may yet respond to another, and so it may be just a matter of finding the right exercise program for you. That study, which was conducted Queen’s University in Kingston, Ontario, and the University of Ottawa, determined that non-responders could benefit by swapping out one form of exercise for another.
