The independent contributions of CRF and PA to metabolic disease risk factors are unknown. We tested the hypothesis that runners who run consistently &gt;50\u2009km\/wk and\/or &gt;2 marathons\/yr for the last 5 years have superior metabolic fitness compared to matched sedentary subjects (CRF, age, gender, and BMI). Case-control recruitment of 31 pairs of runner-sedentary subjects identified 10 matched pairs with similar VO<jats:sub>2max<\/jats:sub>(mL\/min\/kg) (similar-VO<jats:sub>2max<\/jats:sub>). The similar-VO<jats:sub>2max<\/jats:sub>group was compared with a group of age, gender, and BMI matched pairs who had the largest difference in VO<jats:sub>2max<\/jats:sub>(different-VO<jats:sub>2max<\/jats:sub>). Primary outcomes that defined metabolic fitness including insulin response to an oral glucose tolerance test, fasting lipids, and fasting insulin were superior in runners versus sedentary controls despite similar VO<jats:sub>2max<\/jats:sub>. Furthermore, performance (velocity at VO<jats:sub>2max<\/jats:sub>, running economy), improved exercise metabolism (lactate threshold), and skeletal muscle levels of mitochondrial proteins were superior in runners versus sedentary controls with similar VO<jats:sub>2max<\/jats:sub>. In conclusion subjects with a high amount of PA have more positive metabolic health parameters independent of CRF. PA is thus a good marker against metabolic diseases.<\/jats:p>","DOI":"10.1155\/2015\/806418","type":"journal-article","created":{"date-parts":[[2015,3,3]],"date-time":"2015-03-03T16:02:19Z","timestamp":1425398539000},"page":"1-11","source":"Crossref","is-referenced-by-count":18,"title":["Physical Activity Enhances Metabolic Fitness Independently of Cardiorespiratory Fitness in Marathon Runners"],"prefix":"10.1155","volume":"2015","author":[{"given":"M.
