Exercise Can Heal Mental Pain, Says Study

A new study shows for the first time that low and high exercise intensities differentially influence brain function and can be used as therapeutic tools for psychological wellbeing.

In the study, 25 male athletes underwent individual assessments using an incremental treadmill test – the behavioral data showed a significant increase in positive mood after exercise.

On separate days they performed low- and high-intensity exercise bouts for 30 minutes, and before and after exercising, Rs-fMRI was used to examine the functional connectivity of different brain regions that are linked to specific behavioral processes.

Participants also completed a questionnaire to measure positive and negative mood before and after the exercise.

Using resting-state functional magnetic resonance imaging (Rs-fMRI), a noninvasive technique that allows for studies on brain connectivity, researchers discovered that low-intensity exercise triggers brain networks involved in cognition control and attention processing, while high-intensity exercise primarily activates networks involved in affective/emotion processing.

Henning Boecker, MD, Functional Neuroimaging Group, Department of Radiology, University Hospital Bonn, Bonn, Germany, said: “We believe that functional neuroimaging will have a major impact for unraveling body-brain interactions.

“These novel methods allow us to ‘look’ directly into the brains of a group of athletes, and, maybe even more importantly, understand the dynamic changes in brain structure and function associated with the transition from a sedentary to a healthy lifestyle.”

The results of the Rs-fMRI tests showed that low-intensity exercise led to increased functional connectivity in networks associated with cognitive processing and attention.

High-intensity exercise, on the other hand, led to increased functional connectivity in networks related to affective, emotional processes. High-intensity exercise also led to a decreased functional connectivity in networks associated with motor function.

Future research in this area will help provide neurobiological evidence about what type of exercise intensity is best suited for certain neurological or behavioral modulations and may pave the way for supportive clinical applications in patients or for enhancing brain functional plasticity.

  1. Unfortunately the very time you need to exercise to improve severe depression is the time you can nit make yourself do it. I certainly feel better with exercise than without but if these people are suggesting exercise is a cure then I believe they are wrong. If on the other hand their investigations lead them onto other ways to permanently improve mood then that will be beneficial. I have all too often seen apparently ground breaking studies which turn out to be a severe disappointment. The pressure to produce papers to succeed in an academic career may be to blame.
