| Abstract | INTRODUCTION: Physical activity activates brain regions and transmitter systems that represent the reward system (i.e., the ventral striatum [VS] and dopamine). To date, the effect of training status and acute exercise on reward processing has not been investigated systematically in humans. To address this issue, we examined highly trained (HT) physically inactive (PIA) men with a monetary incentive delay (MID) paradigm. METHODS: We used functional magnetic resonance imaging (fMRI) to investigate the neural correlates of monetary incentive processing after acute exercise. HT and PIA subjects were randomized into two groups. Subjects in one group ran on a treadmill (T) for 30 min at 60%-70% of their maximal oxygen uptake (VË O2max), whereas subjects in the other group performed placebo exercise (P). Approximately 1 h after exercise, the MID task was conducted. Mood was assessed using the Positive and Negative Affect Schedule before and after the exercise intervention. RESULTS: The psychological assessment showed that exercise significantly increased mood in HT and PIA men. During gain anticipation and gain feedback of the MID task, the VS was significantly stronger activated in the placebo group than in the treadmill group. No effect of training status and no interactions between training status and acute exercise were found. CONCLUSIONS: Acute exercise diminishes sensitivity to monetary rewards in humans. This finding is discussed concerning interactions between tonic and phasic dopamine in the VS. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
