Brief Summary
This study seeks to determine whether a simple, single intervention of Cetirizine / Zyrtec® use can improve exercise performance of active individuals when acutely exposed to altitude. For this project, healthy subjects will perform steady state and progressive work rate exercise, endurance performance time trials, and repeated sprint performance time trials in the laboratory at a simulated altitude of 3000m (9900ft) after dosing with 10 mg of Cetirizine or a placebo in a repeated measures design.

Study Arms (3)
Cetirizine/Hypoxia
EXPERIMENTALSubjects orally ingested 10 mg of Cetirizine 60 min before exercising in a normobaric hypoxic environment (14.3% oxygen simulating an altitude of 3,000m/9,000ft).
Placebo/Normoxia
PLACEBO COMPARATORSubjects orally ingested a 10 mg gelatin Placebo 60 min before exercising in a normoxic (room-air) environment (20.9% oxygen).
Placebo/Hypoxia
PLACEBO COMPARATORSubjects orally ingested a 10 mg Placebo 60 min before exercising in a normobaric hypoxic environment (14.3% oxygen simulating an altitude of 3,000m/9,000ft).
Interventions
Exposure to a 14.3% oxygen environment simulating an altitude of 3,000m/9,000ft
Eligibility Criteria
You may qualify if:
- Physically active a minimum of 120 minutes a week, as determined by questionnaire
- years of age
- Classified as low risk, based on the modified PAR-Q questionnaire, BMI, and non-smoking status
- No history of pulmonary disease and pulmonary function classified as normal, as defined by the following measurements being 80% of predicted values: forced vital capacity (FVC), forced expired volume in one second (FEV1) and FEV1/FVC, according to the American Thoracic Society standards.
You may not qualify if:
- Current smoker
- Women who are pregnant or could possibly be pregnant
- BMI \> 25 kg/m2
- A 'yes' answer to any of the 14 questions on the PAR-Q pre-participation questionnaire
- History of pulmonary disease or \<80% of predicted FCV, FEV1 and/or FEV1/FVC.
- A history of renal or liver disease, due to possible interaction effect with Cetirizine
- Currently taking any prescription or over the counter medications for the treatment of allergies, or taking any of the below listed drugs known to have a moderate or higher interaction effect with Cetirizine:
- isocarboxazid tranylcypromine bosutinib clobazam crizotinib daclatasvir eliglustat hyaluronidase lomitapide lurasidone ombitasvir/paritaprevir/ritonavir phenelzine ponatinib ritonavir vemurafenib
