There is strong evidence that physical activity acutely reduces cigarette craving
AIMS To conduct an up date d systematic review and the first meta- analysis of experimental trials investigating the acute effects of short bouts of physical activity ( PA ) on strength of desire ( SoD ) and desire to smoke ( DtS ) using individual participant data ( IPD ) .
Acute exercise modulates cigarette cravings and brain activation in response to smoking-related images: an fMRI study
Rationale Substances of misuse ( such as nicotine ) are associated with increases in activation within the mesocorticolimbic brain system , a system thought to mediate the rewarding effects of drugs of abuse . Pharmacological treatments have been design ed to reduce cigarette cravings during temporary abstinence . Exercise has been found to be an effective tool for controlling cigarette cravings . Objective The objective of this study is to assess the effect of exercise on regional brain activation in response to smoking-related images during temporary nicotine abstinence . Method In a r and omized crossover design , regular smokers ( n = 10 ) undertook an exercise ( 10 min moderate-intensity stationary cycling ) and control ( passive seating for same duration ) session , following 15 h of nicotine abstinence . Following treatments , participants entered a functional Magnetic Resonance Imaging ( fMRI ) scanner . Subjects viewed a r and om series of smoking and neutral images for 3 s , with an average inter-stimulus-interval ( ISI ) of 10 s. Self-reported cravings were assessed at baseline , mid- , and post-treatments . Results A significant interaction effect ( time by group ) was found , with self-reported cravings lower during and following exercise . During control scanning , significant activation was recorded in areas associated with reward ( cau date nucleus ) , motivation ( orbitofrontal cortex ) and visuo-spatial attention ( parietal lobe , parahippocampal , and fusiform gyrus ) . Post-exercise scanning showed hypo-activation in these areas with a concomitant shift of activation towards areas identified in the ‘ brain default mode ’ ( Broadmanns Area 10 ) . Conclusion The study confirms previous evidence that a single session of exercise can reduce cigarette cravings , and for the first time provides evidence of a shift in regional activation in response to smoking cues
