Introduction: Low availability of oxygen at tissue level has great impact on systemic physiology. In last few years different altitude training methods have been adopted to enhance performances of various endurance as these methods are legal, safe and easy to implement. Many of the hypoxic training protocols were existed; namely 9live high - train high9 (LHTH), 9live high - train low9(LHTH) and 9live low - train high9 (LLTH). In spite of the availability of these various training modalities, there is a widespread interest to find out which method is more suitable for endurance players in Indian continent. Aims and objectives: The main aim of the current study was to find out whether LHTL hypoxic training has any beneficial effect to the long distance runners. Methods: Eighteen male elite long distance runners were selected from Sports Authority of India, NRC, Sonepat. They were subjected for 2500m normobaric altitude using LOSA LOW, GmbH, Germany for 4 hrs per day, consecutively for 3 weeks with increment of 500m in every week. Complete hemogram and VO2max were carried out before and after the hypoxic training. Results: Our result clearly indicates that LHTL has significantly increased red blood cell count, hematocrit and hemoglobin concentration were respectively 5.8±1.1 to 6.2±1.4 (p Conclusion: Current study strongly implicates that LHTL hypoxic training has substantial beneficial effect. It clearly indicate that erythrocyte mass has increased which might be due to hypoxia induced erythropoietin mediated polycythemia. |
