Répercussions d'une prise chronique de salbutamol au cours d'un exercice supramaximal

Abstract: Introduction. – The aim of the study is to assess the effects of chronic therapeutical β2-agonist intake on performance during supramaximal dynamic exercise. Synthesis. – We studied, according to a double-blind, randomized cross-over protocol, the effects of chronic salbutamol intake (Sal) during a supramaximal anaerobic Wingate test in 15 healthy male volunteers. Body composition and performance were monitored in this study. Sal increases significantly maximal anaerobic power whereas no change is found in body composition. Conclusion. – These results rule out any implication of an anabolic effect of β2-agonist in this improvement in performance with salbutamol during supramaximal exercise. [Copyright &y& Elsevier]
