The decision of whether to partake in physical activity (PA) or remain sedentary appears to be partially influenced by motivational and emotional systems. Research suggests left frontal alpha asymmetry is a neural marker of approach motivation. However, studies have not explored whether habitual levels of PA and sedentary behavior relate to this neurophysiological signal. Across two studies, individuals completed measures of habitual PA and sedentary behavior using the International Physical Activity Questionnaire\u2010Short Form. Then, resting electroencephalography activity was recorded. Results of Study 1 (<jats:italic>N<\/jats:italic>\u00a0=\u00a032, 72% women) indicated that more time spent sitting on both weekdays and weekend days were associated with less left frontal asymmetry (<jats:italic>r =<\/jats:italic> \u2212.45, <jats:italic>p<\/jats:italic> = .027, and <jats:italic>r = \u2212<\/jats:italic>.55, <jats:italic>p<\/jats:italic> = .005, respectively). Study 2 recruited a larger sample (<jats:italic>N<\/jats:italic>\u00a0=\u00a096, 31% women) and investigated moderators. Greater levels of moderate (<jats:italic>r =<\/jats:italic> .27) and total (<jats:italic>r =<\/jats:italic> .29) PA were associated with greater left frontal asymmetry (<jats:italic>p<\/jats:italic>s &lt; .05), and the relationship between sedentary behavior and less left frontal asymmetry was moderated by sex (weekday: <jats:italic>\u03b2<\/jats:italic> = .62, <jats:italic>p<\/jats:italic> = .011; weekend day: <jats:italic>\u03b2<\/jats:italic> = .41, <jats:italic>p<\/jats:italic> = .034). Our results suggest that left frontal asymmetry may be a novel neurophysiological marker for PA and sedentary behavior.<\/jats:p>","DOI":"10.1111\/psyp.13633","type":"journal-article","created":{"date-parts":[[2020,7,14]],"date-time":"2020-07-14T15:58:53Z","timestamp":1594742333000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Frontal asymmetry: A novel biomarker for physical activity and sedentary behavior"],"prefix":"10.1111","volume":"57","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3620-5959","authenticated-orcid":false,"given":"A.
