Circulating angiogenic cells (CACs) are a diverse group that have been identified as predictors of cardiovascular health and are inversely proportional to cardiovascular disease (CVD) outcomes. Inactivity is a growing concern in industrialized nations and is an independent risk factor for CVD. There is limited evidence regarding the impact of reduced physical activity (rPA) on different CAC populations. The purpose of this study was to evaluate the effect of objectively monitored rPA with maintained energy balance on two CAC populations (CFU and CD34+cells), intracellular nitric oxide (NOi), and genes related to NO production in active, healthy men. Participants (age 25 …

Defining the "dose" of altitude training: how high to live for optimal sea level performance enhancement. J Appl Physiol 116: 595-603, 2014. First published October 24, 2013; doi:10.1152/japplphysiol.00634.2013.-Chronic living at altitudes of 2,500 m causes consistent hematological acclimatization in most, but not all, groups of athletes; however, responses of erythropoietin (EPO) and red cell mass to a given altitude show substantial individual variability. We hypothesized that athletes living at higher altitudes would experience greater improvements in sea level performance, secondary to greater hematological acclimatization, compared with athletes living at lower altitudes. After 4 wk of group sea level training and …
