BACKGROUND: The purpose of this research was to evaluate the new concept’s highland training effect called “living high-training low (LHTL) along with the Sprint Interval Training (SIT)”.
METHODS: The training was executed in an altitude of around 600m-1,200m. Moreover, the training was conducted for a total of six weeks (4 weeks’ training and 2 weeks’ recovery) by elite level college wrestling athletes in the altitude of 2500-4000 m with the living high - train low figure. The experimental group (LHTL) executed SIT along with the hypoxic training, and the control group (CON) only executed SIT. The hypoxic training was executed 5 times a week for 8 hours a day. SIT was executed 3 times a week and both groups executed SIT twice a day.
RESULTS: Time, VO2max, and VEmax showed significant increase in the aerobic exercise skill variable (time, VEmax: Pre vs. 3000, 3500, 4000 m; VO2max: Pre vs. 3500, 4000 m). Also, in the anaerobic exercise, skill variable due to WAnT, LHTL group especially showed significant increase in PP (W, W/kg) (W: Pre vs. 3500, 4000 m; W/kg: Pre vs. 3000, 3500, 4000 m), and CON group showed significant increase in peak power (W) in the results (Pre vs. 4000 m, Rec.1, Rec.2).
CONCLUSIONS: CON group showed the tendency to show effect due to SIT in the anaerobic variable and LHTL showed that comprehensive effect of hypoxic training as well as SIT took effect.
