Healthy Active Athletes Clinical Trial
Official title:
Intermittent Hypoxic Training (IHT) Versus Hyperbaric Oxygen Therapy (HBOT) for Aerobic Performance - Prospective Randomized Study
Comparing the effect of HBOT and IHT on aerobic performance of athletes.
Enhanced physical performance is the goal of all professional and non-professional athletes. There are many intervention methods aim to enhance physical performance from 2 intervention related to change in the environment partial oxygen pressure have been demonstrated to have beneficial effect: IHT and HBOT. This study offers one of the two interventions to athletes with a pre and post intervention objective evaluation of the physiological performance - Maximal exercise test for evaluating VO2MAX and ventilatory thresholds, time to exhaustion, 30 seconds Wingate test, agility test, muscle biopsy, blood tests, brain MRI, cognitive tests and exercise cognitive test. After signing an informed consent form, eligible subjects will be randomized to one of the study groups at a ratio of 1:1. The IHT group will receive three hypoxic guided training sessions per week, according an individualized training protocol, 24 sessions in total. The HBOT group will receive 40 daily hyperbaric sessions, five days per week. Each session will include 90 minutes exposure to 100% oxygen at 2ATA with a five-minute air break every 20 minutes. Three times per week, as the IHT group, the HBOT group will have a guided training session, according an individualized training protocol. Both groups, IHT and HBOT, will have the same relative intensity guided training protocols for 8 weeks, to stimulate the same exercise load. The IHT group will train for 60 minutes, 3 times a week in a normobaric hypoxia environment, at O2 concentration of 15.2% that stimulates a 2500-2600m height. The HBOT group will train for 60 minutes after the HBOT sessions, 3 times per week, in a normobaric normoxic environment Physical performance evaluations will be conducted on 3 different times post interventions - a day last intervention, 3 weeks after and 2 months after - in order to analyze the long term effect of each intervention. ;
