Abstract

Oxidative stress markers are novel factors shown to be related to cardiovascular (CVD) risk. We examined the effects of long-term exercise, age, and their interaction on plasma oxidized LDL (ox-LDL), nitrotyrosine, and myeloperoxidase (MPO) levels, all biomarkers of oxidative stress, and determined their association with plasma nitric oxide (NOx) levels as an index of NO bioavailability. Older (62±2 yr) active men (n=12) who had exercised for >30 years and young (25±4 yr) active men (n=7) who had exercised for >3 years were age- and BMI-matched to older (n=11) and young (n=8) inactive men. Young subjects had lower plasma nitrotyrosine levels than older subjects (P=0.047). Young inactive subjects had higher ox-LDL levels than either the young active (P=0.042) or the older active (P=0.041) subjects. In addition, plasma oxidative stress levels, particularly ox-LDL, were correlated with various conventional plasma lipoprotein-lipid levels, and in older subjects were associated with Framingham risk score (r=0.49, P=0.015). We found no relationships between plasma oxidative stress markers and NOx levels. The findings suggest that a sedentary lifestyle may be associated with higher ox-LDL levels and that the levels of oxidative stress markers are related to levels of other conventional CVD risk factors and overall CVD risk.

  • Sedentary lifestyles, characterised by inactive skeletal muscle, sarcopenia and adipose tissue accumulation, are associated with moderate-to-high levels of reactive oxygen species, which can deplete antioxidant defences resulting in oxidation of proteins, lipids and DNA.

    “Sedentary lifestyles, characterised by inactive skeletal muscle, sarcopenia and adipose tissue accumulation, are associated with moderate-to-high levels of reactive oxygen species, which can deplete antioxidant defences resulting in oxidation of proteins, lipids and DNA (Bjork et al. 2012; Derbre et al. 2014; Gratas-Delamarche et al. 2014; Le Lay and Simard 2014).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
