In a variety of laboratory and field studies in my lab here at Santa Clara University, we have found that you can manipulate the psychological experiences of exercise by altering environmental factors unrelated to the actual physical exercise someone is doing. In a nutshell, we have conducted a series of experiments where we randomly assign research participants to different exercise situations such as exercising next to someone who is a friend or a stranger, someone perceived as being highly attractive and fit or unattractive and unfit, or exercising while viewing a highly fit professional athlete versus a non-athlete exercising. In all of these and other conditions we have instructed subjects to exercise at the same pace, intensity, and time (e.g., 20 minutes at 70 percent of maximum heart rate). Results indicate that you achieve very different mood and psychological benefits depending on your exercise environment
while keeping the actual physical exertion and time of the experience constant. For example, people feel more relaxed and calm when exercising alone rather than with others. They often enjoy exercise more outdoors rather than indoors. They tend to feel more stressed exercising near someone who is attractive.
Remarkably, we have found that perceived
fitness (or your belief about your fitness) is a better predictor of the psychological benefits of exercise than an important measure of actual
fitness (as measured by standard fitness assessment or what is called VO2 Max) as well as actual exercise behavior when measured by step counters over several weeks. So, you get more powerful psychological benefits if you believe
you are fit compared to some measures of your actual level of aerobic fitness or exercise behavior.
Thus, your beliefs about exercise and fitness are actually more important than you might think when it comes to many of the psychological benefits of exercise.
So, I'm not saying that the benefits of exercise are all based on expectation or placebo effects but that these expectations do infact matter (and perhaps more than we typically think they do). Go ahead and exercise (it is clearly good for your physical and mental health
) but also be sure to at least pay attention to your exercise beliefs and environment to get the very most from your workouts.
So, what do you think?
