Abstract

Physical exercise has cardioprotective functions, which have been partly linked to high-density lipoprotein (HDL), and its functions. We studied the effects of endogenous oxidative stress, induced by acute exhaustive physical exercise, on concentration of oxidized HDL lipids. Twenty-four male national top-level endurance runners, 12 middle-distance runners and 12 marathon runners performed a maximal run on a treadmill until exhaustion. We analyzed concentrations of oxidized HDL (oxHDLlipids) and LDL lipids (oxLDLlipids), serum antioxidant potential (TRAP), paraoxonase activity and malondialdehyde. Venous blood samples were taken before, immediately, 15 and 90 min after exercise. Immediately after the treadmill run the concentration of oxHDLlipids was increased by 24 % (p < 0.01). Simultaneously, the ratio of oxHDLlipids to oxLDLlipids increased by 55 % and the oxLDLlipids levels decreased by 19 % (p < 0.001), while serum malondialdehyde and TRAP increased by 54 % (p < 0.001) and 29 % (p < 0.01), respectively. After the 90 min recovery the concentration of oxHDLlipids was decreased towards the pre-exercise level, but that of oxLDLlipids remained decreased below pre-exercise values (p < 0.001). The change in oxLDLlipids after the run correlated positively with VO2max (r = 0.67, p < 0.001) and negatively with the change in paraoxonase activity (r = -0.47, p < 0.05). We conclude that acute exhaustive physical exercise increased the concentration of oxHDLlipids and decreased that of oxLDLlipids and the ratio of oxLDLlipids to oxHDLlipids, which suggests that during physical exercise HDL has an active role in the removal of lipid peroxides.

Attention Score in Context

This research output has an Altmetric Attention Score of 8. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 09 July 2016.
All research outputs
#1,846,126
of 12,220,965 outputs
Outputs from European Journal of Applied Physiology and Occupational Physiology
#721
of 2,771 outputs
Outputs of similar age
#54,857
of 269,482 outputs
Outputs of similar age from European Journal of Applied Physiology and Occupational Physiology
#25
of 64 outputs
Altmetric has tracked 12,220,965 research outputs across all sources so far. Compared to these this one has done well and is in the 84th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 2,771 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 10.1. This one has gotten more attention than average, scoring higher than 73% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 269,482 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 79% of its contemporaries.
We're also able to compare this research output to 64 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 60% of its contemporaries.
