Response - NO
Brief Summary   Exposure at high altitude (HA) induced hypobaric hypoxia is known to deteriorate health and decrease performance. The aim of the study is to develop of Rapid Acclimatization Schedule for High Altitude in Western sector using different modalities. 400 volunteers within the age range of 20-40 years will be recruited. The volunteers will be randomized into 4 different groups - Control, Drug treated (Acetazolamide), Stay at Moderate Altitude (Short duration) and Intermittent Hypoxia Exposure (IHE). After recording their baseline parameters at Sea Level area they will be inducted to Stage - I HA by air followed by Stage - II HA by road. In all stages different physiological, physical and biochemical parameters would be assessed.
