説明
Objective: This study aimed to examine the effects of sprint interval training (SIT) exercise under 13.6%O2 hypoxic conditions on muscle tissue oxygenation responses in male college students. Methods: Thirteen active male students participated in the study. SIT exercises consisted of 4 sets of 30-sec cycling exercises with three 4.5-min active recoveries. Participants were instructed to cycle as fast as possible in the 1st and 4th sets; the targeted cycling speed (rpm) in the 2nd and 3rd set of exercises was set at 80% of the peak cycling speed in the 1st set. Near-infrared spectroscopy was attached to the right vastus lateralis muscle, and oxygenation hemoglobin (OxyHb) responses were measured. Results: The mean power output in the hypoxic condition was lower than that in the normoxic condition. OxyHb decreased from the 1st to 3rd SIT exercises in both conditions. OxyHb slightly increased from the 3rd to the 4th SIT exercises in the normoxic condition but not in the hypoxic condition. Conclusion: These results showed that SIT exercises under hypoxic conditions caused greater oxygen deficiency in active skeletal muscles, suggesting that hypoxic SIT could lead to metabolic adaptation in skeletal muscles. However, because of the lower power output of the hypoxic SIT, these results should be interpreted with caution.
