Acute modification in plasma lipid levels in ultramarathon runners.

We aimed to evaluate the effects of a 24-h ultramarathon, an aerobic test of high physical load, on lipid profile and apolipoproteins B (ApoB) and A1 (ApoA1) levels, minimally modified low-density lipoprotein (LDL), and oxidised LDL. Prospective evaluation of 16 male athletes who participated in an ultramarathon run, where the objective was to run the greatest distance possible in 24 h. Fourteen participants completed the run.

Acute effects of prolonged physical exercise: evaluation after a twenty-four-hour ultramarathon.

Background: The consequences and risks of prolonged physical exercise are not well established.

Objective: To evaluate the effects of prolonged physical exercise on the participants of a 24-hour ultramarathon race.

Methods: Twenty male runners were selected for evaluation a day before and immediately after the race, where the athletes had to cover the most distance in 24 hours.
