- Sitting and endothelial dysfunction: the role of shear stressSaurabh S Thosar
Department of Kinesiology, School of Health, Physical Education and Recreation, Indiana University, Bloomington, Indiana, USA
Med Sci Monit 18:RA173-80. 2012..This review furthers the use of sitting as model to study the effects of inactivity, discusses possible physiological mechanisms and suggests future directions...
- The exercise dose affects oxidative stress and brachial artery flow-mediated dilation in trained menBlair D Johnson
Department of Kinesiology, Indiana University, Bloomington, IN 47405, USA
Eur J Appl Physiol 112:33-42. 2012..4 vs. 7.6 ± 2.7%). These data suggest that acute exercise-induced TBARS are exercise intensity-dependent whereas FMD appears to improve following energy expenditure equivalent to 30 min 50% VO(2peak), regardless of intensity or duration...
