Title: Hyperbaric environment and it's impact on physical performance Objectives: To investigate possible impact of of hyperbaric environment on individual's performance compared to normobaric environment with constant physical load. To outline the hyperbaric environment from physical side of view. To determine the usability of these effects for Training and regeneration purposes for athletes. Methods: The five respondents completed two sessions of Kinderman-Schnabell test. There was a seven days gap between hyperbaric and normobaric sessions to exclude the influence of fatique. Each session consisted of 40 seconds of sub-maximal load and a maximal load after 40 minutes rest. The squats were used as anaerobic type of load. The responders were taken a blood samples from finger and earlobe to state the level of lactate. Other measured indicators were blood pressure, heart and respirátory rate. The respondents also stated the subjective level of fatique using visual scale Results: The hyperbaric environment of 3 ATA had a significant effect on heart rate reduction. The sub-max load average was 86 bpm (resp. 99 bpm at normobaric environment) and the max-load average was 101 bpm (resp. 120 bpm normobaric). No significant effect was measured on blood pressure level averages. The sub-max load indicated...
