Purpose: this study was to investigate effects of artificial hypoxic chamber training on acclimatization and aerobic performance of distance runner. Method: Eighteen volunteered college distance runners were randomized into three groups; simulated hypoxia training plus altitude training (SHT + AT), sea level training plus altitude training (CON + AT) and sea level training (CON + CON), respectively. All participants recruited under eight weeks programs with identical training intensity and quantity within three groups, the first four weeks was sea level training program (CON + AT and CON + CON) and hypoxia chamber (SHT + AT), then the second four weeks follow up altitude training at China for SHT + AT and CON + AT groups, also the CON + CON group was still under sea level training. During this study, anaerobic threshold, □O2max, 12 minutes field running tests performance and oxygen saturation (SPO2) were evaluated for three times and the data were statistics via two-way ANOVA. Results: SHT+AT was better than CON + AT at first trial (4.47 ± 0.45, 3.92 ± 0.13 L/min, p < .05); in second and third trail, SHT+AT was still better than CON + AT and CON + CON significantly (4.83 ± 0.52, 4.28 ± 0.44, 4.19 ± 0.37; 5.13 ± 0.24, 4.41 ± 0.73, 4.14 ± 0.40 L/min, p < .05) in □O2max test. Conclusions: hypoxia chamber training could enhance physical acclimatization and shorten adapting duration. Athletes could early reach higher quality and quantity of training efficiency.
