Abstract:Objective: To use portable hyperbaric hyperbaric oxygen chamber as recovery equipment to compare the changes of soft hyperbaric oxygen chamber recovery and routine natural recovery indexes after high-intensity intermittent exercise. Analyze the effect of soft hyperbaric oxygen chamber recovery for future athletes' participation and training. Quick recovery provides new methods and basis. Methods: Female students of sports training majors in a physical education college were selected and divided into 15 groups (21.15±2 yrs; height 165.75±4.27 cm; body weight 57.4±4.3 kg) in the traditional recovery group and 15 people in the recovery group of soft hyperbaric oxygen chamber (age 20.85±1.02 yrs; height 166.25±3.56 cm; body weight 58.5±6.30 kg) as the subject, secondary athlete. The two groups of subjects completed the traditional recovery and soft hyperbaric oxygen chamber recovery for 60 minutes after completing three 30 s full-force high-strength intermittent training. Immediately before, immediately after exercise, immediately before and immediately after recovery, HR and BLA indicators were collected. RPE and response indicators were collected immediately before, immediately after exercise, and immediately after recovery. Blood pressure, CK, and blood pressure were collected on the morning and the next morning of the day of recovery. Blood physiological and biochemical indicators such as BUN, T and C were tested on the recovery day and the next day. Using statistical data of SPSS 21.0 statistical software, the variance test of test indicators at different time points uses the analysis of variance of repeated measurements. Results: Compared with the traditional recovery, the recovery of BLA, RPE, reaction time and sports performance indicators after soft hyperbaric oxygen chamber recovery was significantly different (P<0.05); HR, BUN, CK, T and C after soft hyperbaric oxygen chamber recovery There was no significant difference between the indexes of Hb, blood pressure and traditional recovery (P>0.05). Conclusion: The soft hyperbaric oxygen chamber recovery can speed up the body's blood lactic acid clearance, promote nervous system fatigue recovery, and has a good placebo effect in the psychological, which is beneficial for athletes to adjust the exercise state and achieve excellent athletic performance; soft hyperbaric oxygen chamber can be used as a This kind of safe and effective exercise fatigue recovery equipment is especially suitable for the rapid recovery period between competitions and worthy of further promotion.
