Ibuprofen does not affect serum electrolyte concentrations after an ultradistance run.

Objective: To determine the effects of ibuprofen on serum electrolyte concentrations after a 160 km running race.

Methods: Twenty nine subjects (mean (SD) age 47.9 (7.

Ibuprofen use, endotoxemia, inflammation, and plasma cytokines during ultramarathon competition.

The primary purpose of this study was to measure the influence of ibuprofen use during the 160-km Western States Endurance Run on endotoxemia, inflammation, and plasma cytokines. Subjects included 29 ultramarathoners who consumed 600 and 1200 mg ibuprofen the day before and on race day, respectively, and 25 controls that competed in the race but avoided ibuprofen and all other medications. Blood and urine samples were collected the morning prior to and immediately following the race, and subjects recorded muscle soreness during the week following the race using a 10-point Likert scale (DOMS).

Indirect calorimetry during ultradistance running: a case report.

The purpose was to determine the energy expenditure during ultradistance trail running. A portable metabolic unit was carried by a male subject for the first 64.5 km portion of the Western States 100 running race.

Muscle damage is linked to cytokine changes following a 160-km race.

Muscle damage and perceived soreness following the 160-km Western States Endurance Run were related to changes in plasma cytokines and use of nonsteroidal anti-inflammatory drugs (NSAIDS). Subjects included 60 ultramarathoners (mean+/-SE, age 45.3 +/- 1.
