        Purpose & Background: This study aimed to evaluate the effects of hypoxia training on lung volumes, capacity and record of swimming crawl in adolescent elite swimmersMethodology: 22 of elite swimmers with the average age of 15±1.90 were selected non-randomly and purposefully. The experimental group for 8 weeks and 3 sessions per week (24 sessions) were swimming by hypoxia training. The control group also were swimming in the 8 weeks of regular exercise. Spirometry test record of 48 hours before and 48 hours after exercise were taken from both groupsResults: The variables statistic results showed a significant increase in forced vital capacity FVC, forced expiratory volume in one second FEV1, forced expiratory volume in the first second of the of forced vital pressure FEV1 / FVC, vital capacity inspiratory pressure FIVC, the inspiratory pressure in the first seconds FIV1, ratio of inspiratory pressure in the first seconds of the vital capacity inspiratory pressure FIV1 / FIVC and record of swimming chest crawl, in hypoxia group.Conclusion: These results suggest that the practice of hypoxia training is likely to affect the volume of lung and respiratory muscles, in addition it can improve swimming performance in adolescent elite swimmers.
