Short-term Effects of Preoperative Exercise in Moderate-to-high Perioperative Risk Lung Cancer Patients

Participants in MICT group will need to additional complete a total of 12 supervised training sessions in 2-3 weeks.After a warm-up of 5 minutes at 50% at peak WR, the patient start exercising at 60%-70% peak WR for 30-40 minutes (four 5-8 minutes sets, with a 2-min rest in between), and then the patients cooled down for 5 minutes at 50% peak WR. Moderate-intensity exercise training intensity control at 55-74% HRmax or 40-69% VO2peak or PRE12-13 as recommended by guidelines.

Participants in HIIT group will need to additional complete a total of 12 supervised training sessions in 2-3 weeks.After a 5-minute warm-up at 50% at peak WR, the patients complete 20 series of vigorous-intensity sprint (80%-100% peak WR for 30-60s) separated by a low-intensity recovery (30% peak WR or completely rest for 15s), and then the patients cooled down for 5 minutes at 50% peak WR. Participants will begin training at a relatively moderate intensity (60%-65% peak WR) for the first 3 sessions and gradually increase to the target intensity beginning on the 4th session. Intensity control of high-intensity exercise training at 75-90% HRmax or 70-85% VO2peak or PRE14-16 as recommended by guidelines.
