Everyone knows exercise is supposed to be
good for your health, but is the belief that exercise will have a
positive effect more important for our well-being than the exercise
itself? The psychologist Hendrik Mothes from the University of
Freiburg's Department of Sport Science and his team have conducted a
study demonstrating that test subjects derive more psychological as well
as neurophysiological benefits from exercise if they already have
positive mindsets about sports. Moreover, the team provided evidence
that test subjects can be positively or negatively influenced in this
regard before engaging in the exercise. The study was published in the Journal of Behavioral Medicine.
The researchers invited 76 men and women aged between 18 and 32 years
to their research laboratory, where they had to exercise for 30 minutes
on a bicycle ergometer. Beforehand, the test subjects were separated
into different groups and shown one of several short films that either
praised the positive effects of cycling on health or not. In addition,
the researchers asked the test subjects whether they had already
believed in the positive effects of physical activity before beginning
the study. The participants filled out questionnaires asking them about
their well-being and their mood before and after the exercise. Moreover,
the researchers measured the participants' brain activity with an
electroencephalogram (EEG).
"The results demonstrate that our belief in how much we will benefit from physical activity has a considerable effect on our well-being in the manner of a self-fulfilling prophecy," sums up Mothes. The results provide evidence for a placebo effect during exercise: Test subjects who already believed the physical activity would have positive effects before participating in the study enjoyed the exercise more, improved their mood more, and reduced their anxiety more than less optimistic test subjects. In addition, the study revealed a neurophysiological difference between the test subjects: According to the measurements of brain activity, the participants with greater expectations before the beginning of the study and those who had seen a film about the health benefits of cycling beforehand were more relaxed on a neuronal level.
The results likely also apply to other endurance sports like jogging, swimming, or cross-country skiing, reports Mothes. "Beliefs and expectations could possibly have long-term consequences, for instance on our motivation to engage in sports. They can be a determining factor on whether we can rouse ourselves to go jogging again next time or decide instead to stay at home on the couch." The psychologist is now working on his next project. He aims to study further effects of mindsets and investigate the question of whether and how they influence the experience of exertion during physical activity.
