Taking eight puffs of terbutaline every day results in a kilo of extra muscle mass 4 weeks later
If you use a bit more of the asthma drug terbutaline than patients usually need, you build over a kilo of muscle mass in a month. This happens when you work out with weights, but also when you just have a lifestyle with sufficient physical activity. Sport scientists from the University of Copenhagen come to this conclusion in a human study, which will soon appear in the Scandinavian Journal of Medicine & Science in Sports.
Many beta-2 agonists also have an anti-catabolic effect, allowing users to build up extra muscle mass. Pharmacological athletes often use beta-2 agonists to make a fat loss diet more effective.
If athletes have asthma, they are allowed use terbutaline. As far as we known, medical doses of terbutaline have no effect on muscle mass. But, the Danes asked themselves, what happens if athletes use more terbutaline than is usually necessary to alleviate asthma?
The men in the first group did not change their exercise patterns [Habitual].
The men in the second group started endurance training. For 4 weeks, 3 times a week, the men did an interval training, which consisted of 3 sessions of 10 minutes of cycling with an intensity of 85 percent of the maximum oxygen uptake. Each session ended with a final sprint of 30 seconds. After the training, the men drank a shake with 30 grams of whey.
The men in the third group started resistance training, 3 times a week. Each training consisted of a full body workout, in which the men trained their main muscle groups with basic exercises such as leg-press, bench-press, extensions, military-press, lunges, lat-pulldowns, leg-curl and low-row. The men made sets of 12 reps, and rested for 2 minutes between sets. After each workout they drank a shake with 30 grams of whey.
In each group, half of the men used terbutaline. The drug was administered drug was administered by inhalation. The men used Bricanyl Turbohaler from AstraZeneca, if you want to know exactly. Every day the men took 8 puffs of 0.5 milligrams of terbutaline. That is 4 milligrams a day.
Terbutaline had no effect on fat mass.
"This is a challenging anti-doping issue, and establishing a urine threshold for terbutaline should be a priority for WADA, in order to avoid excessive misuse for hypertrophic gains by athletes who have acquired terbutaline."
"Nevertheless, data from the present study should be a point of caution for clinicians who are treating elite athletes as terbutaline inhalation in doses of 4 mg, and presumably above, may potentiate training adaptations to resistance training."
