Possible effect of decreased insulin resistance on ferritin levels after Nordic Walking training

Abstract

Birkan Ilhan, Fatih Tufan, Gulistan Bahat, Mehmet Akif Karan Department of Geriatrics, Istanbul School of Medicine, Istanbul University, Istanbul, TurkeyWe read with interest the article by Kortas et al1 entitled “Effect of Nordic Walking training on iron metabolism in elderly women.” In their study, the authors investigated the effect of Nordic Walking (NW) training on serum ferritin, C-reactive protein (CRP), hepcidin, hemojuvelin, and vitamin D, which have been stated as components of the inflammatory system. In this study, while NW training significantly reduced iron stores and increased hemojuvelin and tended to reduce CRP levels, it did not affect hepcidin levels. The authors also observed a significant weight loss after training. The authors concluded NW training has pro-healthy effects manifested by decreased inflammation and a drop in iron stores.View original paper by Kortas et al.
