Abstract

Although considerable research concerning the efficacy of analgesics in sport exists, there is a paucity of data concerning effects of acute acetaminophen (ACT) ingestion on sprint interval running exercise. This investigation concerned the effect of acute ACT ingestion on eight 30 s maximal treadmill sprints on a non-motorized treadmill, interspersed with two-minute rests in males (N=8, age 26±3 years, body height 174±7 cm, body mass 71±8 kg) in a placebo-controlled, randomized crossover design. A time x condition repeated measures analysis of variance (ANOVA) determined ACT ingestion did not influence mean power output, peak power output, peak vertical ground reaction force, peak oxygen uptake, or total distance completed (p>.05). Perceived pain was reduced by 8-15% during the final three sprints following ACT ingestion (p<.05). Data presented here suggest ACT may reduce exercise-induced pain during the latter stages of sprint interval treadmill running, without influencing performance.
