Acetaminophen and Impaired Musculoskeletal Adaptations to Exercise Training
연구 개요
상세 설명
The commonly used pain relievers acetaminophen and ibuprofen may impair musculoskeletal adaptations to progressive resistance exercise training by inhibiting exercise-induced muscle protein synthesis.
To test the hypothesis that acetaminophen and ibuprofen would diminish training-induced increases in fat-free mass, untrained men (n=26) aged ≥ 50 years participated in 16 weeks of high-intensity progressive resistance exercise training and bone-loading exercises and were randomly assigned to take ACET (1000 mg), ibuprofen (400 mg) or placebo 2 hours before each exercise session.
The primary outcome was the change in total body fat-free mass measured by dual-energy X-ray absorptiometry (DXA) at baseline and week 16. Our primary interest was in the comparison of the acetaminophen and placebo groups.
