Effects of acute inhalation of the bronchodilator, albuterol, on power output

Effects of Acute Inhalation of Albuterol on Submaximal and Maximal V̇O2and Blood Lactate

“…2). This is not supported by previous studies administering 180 jig of albuterol (1, 6,10). This is probably due to the larger dose of albuterol (360 jig) used in the present study.…”

“…Resting heart rate, maximal heart rate and VO2max in non-asthmatic individuals have been reported to be not significantly affected by chronic administration of 18O.tg albuterol 4 times per day for a 1 week period (6). Change in heart rate during a power orientated cycle ergometry test has also been reported to be not significantly affected by acute administration of 180 jig albuterol (10).…”

High-dose inhaled terbutaline increases muscle strength and enhances maximal sprint performance in trained men

“…In future studies, it would therefore be interesting to examine whether lower doses of inhaled terbutaline or salbutamol could increase supramaximal performance. Indeed, Signorile et al (1992) found that inhaled albuterol (360 µg) enhanced power output during four 15-s maximal sprints in healthy males and females.…”

“…While several studies have investigated effects of clinical therapeutic inhalation of beta 2 -agonists (2-4 puffs) on submaximal, supramaximal, and time-trial performance (Sporer et al 2008;van Baak et al 2004;McKenzie et al 1983;Carlsen et al 1997;Signorile et al 1992), effects of supratherapeutic high-dose inhalation of beta 2 -agonists are inadequately explored. To our knowledge, only one study by Elers et al (2012b), has investigated the effects of high-dose inhalation of salbutamol (40 × 200 µg) on incremental exercise performance, whereas no studies exist investigating the effects of high-dose inhaled beta 2 -agonist on muscle strength and supramaximal exercise performance.…”

Salbutamol effects on systemic potassium dynamics during and following intense continuous and intermittent exercise

“…Performance during a 30 s cycle sprint was enhanced by oral salbutamol (4-8 mg) (Le Panse et al 2007;Collomp et al 2005;Hostrup et al 2014a), with the post-exercise antecubital (Hostrup et al 2014a (Kalsen et al 2014). Inhalation of the β 2 -agonist albuterol (180 µg) increased peak power during a 15 s cycle sprint (Signorile et al 1992), whilst terbutaline inhalation (450 µg) enhanced 30 s cycle sprint power and reduced post-exercise venous (Hostrup et al 2014b). Investigation of the effects of inhaled salbutamol at a higher dose within WADA approved limits, on arterial [K + ] during and in recovery from intense exercise is warranted.…”
