In this study, hypoxic exposure and training with regard to the current progress during the various models 'live and/or sleep high: train high' by way of 4 weeks in elite level tennis players. The experimental group which SITH(SIT with hypoxic) a 2,500m-4,000m to the graded elevation every 500m increased by the week five times a day, two times four weeks treated to a SIT (sprint interval training) and three hours of exposure in hypoxic chamber(simulated normobaric hypoxic). The CON(control) was conducted same period and methods without exposure to hypoxia that a SIT at sea level. As a results, the haematological variables were Hb and Hct compared Pre with the treatment at the end of 4,000 m(at 4 weeks) has been shown to significantly increased in both groups respectively(p<.05, p<.01; vs. Pre). Aerobic exercise capacity related variables that Time was SITH has been shown to significantly increased at 4,000 m(p<.05; vs. Pre). Also, VO2max was SITH has been showed increased in the same period a tendency(p=.072). Anaerobic exercise capacity related variables that PP(W) was both groups increased significantly at 4,000 m(p<.05; vs. Pre), and PP(W/kg) was CON group has been showed increased in the same altitude a tendency, whereas SITH group has been showed increased at 3,500m and 4,000m respectively(p<.05; vs. Pre). Therefore, this study was unlike previous studies with similar positive results as a follow-up study will be contribute to the attainment of a higher value.
