Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Normal conditions
Urine samples collected after various performance tests in normal conditions
Normal conditions
Participants are administered salmeterol, after which they perform various performance tests in normal conditions. Following the administration of salmeterol, urine samples are collected over the next 24 hours at intervals of 0.5, 1, 2, 4, 8, and 24 hours after administration.
Heated conditions
Urine samples collected after various performance tests in heated conditions
Heated conditions
Participants are administered salmeterol, after which they perform various performance tests in heated conditions. Following the administration of salmeterol, urine samples are collected over the next 24 hours at intervals of 0.5, 1, 2, 4, 8, and 24 hours after administration.
Salmeterol inhalation and urine samples
Participants are administered daily salmeterol inhalation from an MDI device and are required to collect spot urine samples at home.
Salmeterol inhalation and urine samples
After the experimental day under normal conditions, all participants are administered 200 µg of salmeterol daily (8 puffs from the MDI device) during a 6-day intervention period. Two hours after inhalation, the participants collect spot urine samples at home
