Influence of vitamin C supplementation on oxidative and immune changes after an ultramarathon
Open accessAbstract
The purpose of this randomized study was to measure the influence of vitamin C ( n = 15 runners) compared with placebo ( n = 13 runners) supplementation on oxidative and immune changes in runners competing in an ultramarathon race. During the 7-day period before the race and on race day, subjects ingested in randomized, double-blind fashion 1,500 mg/day vitamin C or placebo. On race day, blood samples were collected 1 h before race, after 32 km of running, and then again immediately after race. Subjects in both groups maintained an intensity of ∼75% maximal heart rate throughout the ultramarathon race and ran a mean of 69 km (range: 48–80 km) in 9.8 h (range: 5–12 h). Plasma ascorbic acid was markedly higher in the vitamin C compared with placebo group prerace and rose more strongly in the vitamin C group during the race (postrace: 3.21 ± 0.29 and 1.28 ± 0.12 μg/100 μl, respectively, P < 0.001). No significant group or interaction effects were measured for lipid hydroperoxide, F 2-isoprostane, immune cell counts, plasma interleukin (IL)-6, IL-10, IL-1-receptor antagonist, or IL-8 concentrations, or mitogen-stimulated lymphocyte proliferation and IL-2 and IFN-γ production. These data indicate that vitamin C supplementation in carbohydrate-fed runners does not serve as a countermeasure to oxidative and immune changes during or after a competitive ultramarathon race.

In the citing paper
“For example, a relatively high dose of vitamin C (1500 mg·d− 1) for 7 days prior to a 50 mile (80 km) single-stage race (The Umstead race; NC, USA) failed to induce any group differences in oxidative or immune responses, including lipid hyrdroperoxide and plasma interleukin (IL)-6 [171].”

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.
