The author divided 30 young male basketball players randomly into an experiment group (EG, n=15) and a control group (CG, n=15), let the players in group CG have normal training and let the players in group EG have 2 times of print interval training a week on the basis of normal training for 4 weeks, and respectively before and after the experiment, measured their aerobic exercise capacity by means of progressively increased load experiment, measured their anaerobic exercise capacity by means of 30s Wingate experiment, monitored the chang-ing of vastus lateralis muscle oxygen content during high intensity interval exercise experiment (repeated 5 times of 30s Wingate experiment, interval 4min) by means of near-infrared spectroscopy (NIRS), and revealed the following findings: after the experiment, as compared with those measured before the experiment, the maximum oxygen up-take and maximum aerobic power of the testees in group EG increased (P<0.05) during progressively increased load experiment, their peak power and mean power increased (P<0.05) during 1 time Wingate experiment, during in-terval exercise experiment, the absolute values of change in oxyhaemoglobin+oxymyoglobin (HbO2+MbO2), de-oxyhaemoglobin+deoxymyoglobin (HHb+HMb) and tissue oxygenation index (TSI) increased significantly (P<0.05), while total haemoglobin (tHb) had no significant change (P>0.05); all the indexes of the testees in group CG had no significant change (P>0.05). The said findings indicated that short-term print interval training improved the aerobic and anaerobic exercise capacities of young male basketball players as well as their peripheral skeletal muscle’s oxygen uptake capacity during interval exercise.
